Referring to fig. 1, fig. 2 and fig. 3, an adjusting mechanism 4 is arranged between the bearing seat 1 and the sliding bearing bush 2, the adjusting mechanism 4 comprises a fixed structure 41 and an adjusting component 42, the fixed structure 41 is connected with the bearing seat 1, it should be noted that the fixed structure 41 and the bearing seat 1 can be fixedly connected or detachably connected, one side of the fixed structure 41 away from the bearing seat 1 is provided with an inclined plane 410, i.e. the lower end of the fixed structure 41 is provided with an inclined plane 410; the adjusting assembly 42 includes a driving structure 421, and the driving structure 421 may be fixedly connected with the bearing seat 1 or detachably connected with the bearing seat 1, for example, by a bolt. The adjusting assembly 42 further includes an adjusting member 420, and an adjusting member inclined surface 410a matched with the inclined surface 410 on the fixing structure 41 is provided at the upper end of the adjusting member 420, and the two inclined surfaces are mutually abutted and can slide relatively.

The adjusting piece 420 is connected with the corresponding sliding bearing bush 2, and as shown in fig. 3, the lower end of the adjusting piece 420 is abutted with the upper end of the sliding bearing bush 2 and can slide relatively; the adjusting member 420 is connected with the driving structure 421, and when the driving structure 421 drives the adjusting member 420 to slide along the inclined plane 410, the fixing structure 41 pushes the adjusting member 420 to move downwards through the inclined plane 410, so that the adjusting member 420 pushes the sliding bearing bush 2 to move downwards, and the distance between the sliding bearing bush 2 and the rotating shaft 3 is reduced.

By arranging the adjusting mechanism 4 between the bearing seat 1 and the sliding bearing bush 2, the clearance between the sliding bearing bush 2 and the rotating shaft 3 can be adjusted, so that the clearance between the sliding bearing bush 2 and the rotating shaft 3 is in a proper range, and the normal operation of the bearing device is ensured.

In some embodiments of the present application, the driving structure 421 includes an adjustment screw 4210 and a connection 4211. As shown in fig. 3, the connecting member 4211 is connected to the bearing housing 1, and the connecting member 4211 may be fixedly connected to the bearing housing 1 or may be connected by a bolt. The right end of the connecting piece 4211 is provided with a screw hole, the adjusting screw 4210 is sleeved in the screw hole, and the length direction of the adjusting screw 4210 is consistent with the sliding direction of the adjusting piece 420; one end of the adjusting screw 4210 is rotatably connected with the adjusting member 420, that is, the left end of the adjusting screw 4210 is connected with the right end of the adjusting member 420 in the figure, and the adjusting screw 4210 and the adjusting member 420 can rotate relatively but cannot be separated.

When the adjusting screw 4210 is screwed to rotate, the adjusting screw 4210 moves in a horizontal direction, and when the adjusting screw 4210 is rotated clockwise, the adjusting screw 4210 may move horizontally leftwards or horizontally rightwards, and the rotation direction of the adjusting screw 4210 and the horizontal movement direction corresponding to the rotation direction may be determined according to the actual situation, and the present invention is not limited thereto. When the adjusting screw 4210 moves leftwards, the adjusting member 420 is driven to slide leftwards along the inclined surface 410, and the adjusting member 420 moves downwards under the action of the inclined surface 410 so as to push the sliding bearing bush 2 to move downwards, so that the distance between the sliding bearing bush 2 and the rotating shaft 3 is reduced.

Through setting up connecting piece 4211 and adjusting screw 4210, rotatory adjusting screw 4210 can conveniently realize the regulation of the distance between slide bearing tile 2 and the pivot 3, and the less space that the structure of adjusting screw 4210 took can not cause the influence to other structures in the bearing device, and it is also comparatively convenient during the installation.

It should be noted that, referring to fig. 1, 2 and 3, the adjusting end of the adjusting screw 4210 faces into the gap 33, so that a worker can conveniently rotate the adjusting screw 4210 to adjust the adjusting member 420 when entering into the gap 33.

In some embodiments of the present application, a connecting portion 4201 is disposed on a side of the adjusting member 420 near the adjusting screw 4210, the connecting portion 4201 has an abutment surface 4202 opposite to the end surface 12 of one end of the adjusting screw 4210, an abutment portion 4210a is disposed on one end of the adjusting screw 4210, and the abutment portion 4210a abuts against the abutment surface 4202; the regulating member 420 is connected with a limiting member 423, and the limiting member 423 is located at a side of the abutting portion 4210a facing away from the abutting surface 4202.

As shown in fig. 3, the right end of the adjusting member 420 is provided with a connecting portion 4201, the right end surface of the connecting portion 4201 is an abutment surface 4202, the left end of the adjusting screw 4210 is provided with an abutment portion 4210a, and the abutment portion 4210a abuts against the abutment surface 4202; the right end of the connecting portion 4201 on the adjusting member 420 is provided with a limiting member 423, the limiting member 423 is located at the right end of the abutting portion 4210a on the adjusting screw 4210, and the limiting member 423 and the connecting portion 4201 may be fixedly connected or detachably connected.

When the adjusting screw 4210 moves horizontally leftwards, the abutting portion 4210a on the adjusting screw 4210 abuts against the abutting surface 4202 on the connecting portion 4201, the adjusting member 420 is pushed to move leftwards, the adjusting member 420 moves downwards under the action of the inclined surface 410, so that the sliding bearing bush 2 is pushed to move downwards, and the distance between the sliding bearing bush 2 and the rotating shaft 3 is reduced; when the adjusting screw 4210 moves horizontally rightward, the limiting member 423 prevents the adjusting screw 4210 and the adjusting member 420 from being separated, that is, the adjusting screw 4210 can also drive the adjusting member 420 to move horizontally rightward, so that the adjusting structure can perform bidirectional adjustment.

In some embodiments of the present application, the abutment surface 4202 is provided with a recess at a position corresponding to the abutment portion 4210a, the abutment portion 4210a being received in the recess, the recess having a space for the abutment portion 4210a to move in a direction from the corresponding slide bearing shoe 2 to the bearing housing 1.

As shown in fig. 3, the right end of the connection portion 4201 and the abutting surface 4202 are provided with grooves 4202a, the abutting portion 4210a is located in the groove, a vertical gap is formed between the abutting portion 4210a and the connection portion 4201, that is, a vertical gap is formed between the adjusting member 420 and the adjusting screw 4210, and the adjusting member 420 and the adjusting screw 4210 can move relatively in the vertical direction.

After the recess 4202a is formed on the adjusting member 420, when the adjusting screw 4210 is connected to the adjusting member 420, the adjusting screw 4210 may be positioned in the recess 4202a, and then the limiting member 423 is mounted on the adjusting member 420, so that the assembly between the adjusting screw 4210 and the adjusting member 420 is easier.

Because the adjusting piece 420 is matched with the fixed structure 41 through an inclined plane, after the adjusting screw 4210 drives the adjusting piece 420 to move horizontally and rightwards, a gap in the vertical direction is generated between the adjusting piece 420 and the fixed structure 41; because there is also a gap in the vertical direction between the adjustment member 420 and the adjustment screw 4210, the adjustment member 420 can move upward relative to the adjustment screw 4210, creating a gap between the adjustment member 420 and the sliding bearing bush 2, leaving room for upward movement of the sliding bearing bush 2; when the rotating shaft 3 moves upwards due to the load, the rotating shaft 3 can push the sliding bearing bush 2 to move upwards, so that abrasion caused by interference fit between the sliding bearing bush 2 and the rotating shaft 3 is avoided. It will be appreciated that the size of the gap may be adjusted according to the actual situation, and is not limited herein.

In addition, since a gap is provided between the connection portion 4201 of the adjusting member 420 and the abutting portion 4210a of the adjusting screw 4210, the adjusting member 420 has a space for moving downward, and when the adjusting screw 4210 drives the adjusting member 420 to slide leftwards, the fixing structure 41 can push the adjusting member 420 to move downward through the inclined surface 410, so that the locking of the adjusting mechanism 4 is avoided.

In some embodiments of the present application, the limiting member 423 is connected to the adjusting member 420 and covers the recess, the limiting member 423 is provided with a limiting member through hole 423a, the screw rod passes through the limiting member through hole 423a, and the limiting member through hole 423a has a space for the abutting portion 4210a to move in a direction from the corresponding sliding bearing bush 2 to the bearing housing 1.

As shown in fig. 3, the limiting member is connected to the adjusting member 420, and the limiting member covers the recess, i.e., the limiting member is disposed at both upper and lower portions of the adjusting screw 4210, so that the adjusting screw 4210 and the adjusting member 420 can be better connected. The limiting member 423 is provided with a limiting member through hole 423a through which the adjusting screw 4210 passes, and a gap is formed between the adjusting screw 4210 and the limiting member through hole 423a, so that the adjusting member 420 and the limiting member 423 can move upwards relative to the adjusting screw 4210; after the adjusting screw 4210 drives the adjusting member 420 to move horizontally to the right, the adjusting member 420 can move upwards relative to the adjusting screw 4210, so that a gap is formed between the adjusting member 420 and the sliding bearing bush 2, and an upward movement space is reserved for the sliding bearing bush 2; when the rotating shaft 3 moves upwards due to the load, the rotating shaft 3 can push the sliding bearing bush 2 to move upwards, so that abrasion caused by interference fit between the sliding bearing bush 2 and the rotating shaft 3 is avoided. It will be appreciated that the size of the gap may be adjusted according to the actual situation, and is not limited herein.

It should be noted that, the limiting member 423 may be fixedly connected to the adjusting member 420 or may be detachably connected to the adjusting member 420, and in some embodiments of the present application, the limiting member 423 is a nut and is sleeved with the connecting portion 4201 through a thread, so that the structure is simple, and the limiting member 423 is detachable from the adjusting member 420, so that the adjusting member 420 can be replaced when needed.

In some embodiments of the present application, the connecting member 4211 comprises a fixed portion 4211a connected to the bearing housing 1, and a limiting portion 4211b extending from the fixed portion 4211a toward the adjusting member 420, the adjusting screw 4210 is screwed to the fixed portion 4211a, and the connecting portion 4201 is located between the limiting portion 4211b and the bearing housing 1.

As shown in fig. 3, the fixing portion 4211a is connected to the bearing seat 1 through a bolt, so as to facilitate the installation and replacement of the adjusting assembly 42, however, other connection manners, such as welding, may be adopted between the fixing portion 4211a and the bearing seat 1 according to practical situations, and the present invention is not limited thereto. The adjusting screw 4210 is connected with the fixing portion 4211a through threads, the fixing portion 4211a extends towards the adjusting member 420 to form a limiting portion 4211b, a space is formed between the limiting portion 4211b and the bearing seat 1, and the adjusting member 420 and the adjusting screw 4210 are located in the space.

When the adjusting screw 4210 is rotated to move horizontally leftward, the adjusting screw 4210 abuts against the adjusting member 420 to move horizontally leftward, and the sliding of the inclined surface 410 on the fixing structure 41 abuts against the lower adjusting member 420 to move downward. It will be appreciated that there is a vertical clearance between the limiting portion 4211b and the adjustment member 420, i.e. a space is required for the adjustment member 420 to be able to move downward. Since the adjusting screw 4210 can only move horizontally, when the downward displacement of the adjusting member 420 exceeds the vertical clearance between the adjusting member 420 and the adjusting screw 4210, the adjusting member 420 applies a radial force to the adjusting screw 4210; therefore, when the adjusting member 420 moves downward for a certain distance, the limiting portion 4211b can limit the adjusting member 420 from moving downward, so that the excessive force on the adjusting screw 4210 caused by excessive downward displacement of the adjusting member 420 when the adjusting screw 4210 is rotated continuously is avoided, and the risk of breakage of the adjusting screw 4210 caused by larger radial force is reduced.

In some embodiments of the present application, the fixing structure 41 includes a supporting portion 412 and a positioning portion 411, the inclined surface 410 is disposed on the supporting portion 412, and a side of the supporting portion 412 facing away from the inclined surface 410 abuts against the bearing seat 1;

the positioning portion 411 includes a first sub-positioning portion 411a and a second sub-positioning portion 411b, and the first sub-positioning portion 411a and the second sub-positioning portion 411b are distributed on both sides of the supporting portion 412 along the sliding direction of the adjusting member 420 to limit the sliding of the supporting portion 412 along the sliding direction of the adjusting portion.

As shown in fig. 3, the lower surface of the supporting portion 412 is a slope 410, and the upper surface of the supporting portion 412 abuts against the bearing housing 1. The first sub-positioning part 411a and the second sub-positioning part 411b in the positioning part 411 are distributed on two sides of the supporting part 412, so that the supporting part 412 is limited to move leftwards or rightwards, the supporting part 412 is prevented from being driven to move when the adjusting piece 420 slides horizontally, and the normal adjustment of the adjusting mechanism 4 is ensured. The second sub-positioning part 411b is connected with the bearing seat 1, and the second sub-positioning part 411b can be connected with the bearing seat 1 through bolts, so that the installation and the disassembly are convenient.

Due to sliding friction between the inclined surface 410 of the support portion 412 and the adjustment when the adjustment of the plain bearing bush 2 is performed, the surface of the support portion 412 may be worn out after a long period of use of the adjustment mechanism 4. By providing the support portion 412 to be separable from the bearing housing 1, the support portion 412 can be easily replaced when worn.

In some embodiments of the present application, the first sub-positioning portion 411a is disposed on the limiting portion 4211b, the surface of the second sub-positioning portion 411b opposite to the first sub-positioning portion 411a is provided with a avoiding groove 4110, and one end of the adjusting member 420 away from the adjusting screw 4210 is inserted into the avoiding groove 4110.

As shown in fig. 3, the first sub-positioning portion 411a is connected to the limiting portion 4211b, that is, the first sub-positioning portion 411a is connected to the connecting member 4211 in the driving structure 421, and the first sub-positioning portion 411a may be a side plate of the driving structure 421. When the first sub-positioning portion 411a is disposed on the connecting member 4211, the first sub-positioning portion 411a may be mounted on the adjusting assembly 42 before the adjusting assembly 42 is mounted on the bearing housing 1, which is easier to implement in terms of process.

The right side surface of the second sub-positioning portion 411b is provided with a relief groove 4110, and the left end of the adjusting member 420 is located in the relief groove 4110. It should be noted that, the avoiding groove 4110 has a gap that allows the adjusting member 420 to move horizontally and vertically, and the size of the gap affects the movable range of the adjusting member 420, that is, the size of the gap is related to the adjusting range of the adjusting assembly 42; the size of the gap may be determined according to actual conditions, and is not limited herein.

It will be appreciated that the avoidance groove 4110 can limit the displacement of the adjusting member 420, control the adjusting range of the adjusting assembly 42 within a set range, and avoid the occurrence of a larger radial force on the adjusting screw 4210 due to a larger displacement of the adjusting member 420 in the vertical direction, thereby reducing the risk of breakage of the adjusting screw 4210.

In some embodiments of the application, the plurality of plain bearing shoes 2 comprises a guide shoe 21, the guide shoe 21 being arranged at the inner surface 101 of the mounting hole 10, an adjustment mechanism 4 being arranged between the guide shoe 21 and the inner surface 101 of the mounting hole 10; in the axial direction of the rotating shaft 3, the inclined surface 410 is inclined in the direction from the guide shoe 21 to the bearing housing 1; and/or the plurality of sliding bearing shoes 2 comprise thrust shoes, the thrust shoes are arranged on the end face 12 of the bearing seat 1 along the axial direction of the mounting hole 10, and an adjusting mechanism 4 is arranged between the thrust shoes and the end face 12; in the radial direction of the mounting hole 10, the inclined surface 410 is inclined in the direction from the thrust shoe to the end face 12.

Referring to fig. 1,2 and 3, the sliding bearing bush 2 is a guide bush 21, and the guide bush 21 is attached to the inner surface 101 of the bearing housing 1 and is disposed around the rotating shaft 3 to radially support the rotating shaft 3. The adjusting mechanism 4 is provided between the guide shoe 21 and the inner surface 101, and the inner surface 101 abuts against the support portion 412. The inclined surface 410 of the supporting portion 412 is inclined upward or downward, and it will be understood that pushing the adjusting member 420 leftward will move the guide shoe 21 downward when the inclined surface 410 is inclined upward, and pulling the adjusting member 420 rightward will move the guide shoe 21 downward when the inclined surface 410 is inclined downward, i.e. the inclination direction of the inclined surface 410 affects the adjustment mode of the adjustment assembly 42.

The slope of the inclined surface 410 affects the adjustment accuracy of the adjustment mechanism 4. The greater the slope of the inclined surface 410, the greater the distance the guide shoe 21 moves in the radial direction of the rotating shaft 3 when the distance the adjustment assembly 42 moves in the axial direction of the rotating shaft 3 is, but the sensitivity of the adjustment assembly 42 is higher, but the adjustment accuracy is lowered because the guide shoe 21 changes in position in the radial direction of the rotating shaft 3 more greatly, i.e., the guide shoe 21 cannot move in the radial direction of the rotating shaft 3 by a smaller distance. In addition, the greater the slope of the ramp 410, the greater the installation space required for the adjustment assembly 42.

In view of the above, the inclination direction and the slope of the inclined surface 410 need to be determined according to actual situations, which is not limited herein.

Referring to fig. 1,2 and 4, the sliding bearing bush 2 is a thrust bush 22, and the thrust bush 22 is connected to an end face 12 of the bearing block 1 along the axial direction of the mounting hole 10, so as to support the rotating shaft 3 in the axial direction of the rotating shaft 3, and the surface of the left side of the bearing block 1 connected with the adjusting mechanism 4 is the end face 12. The adjusting mechanism 4 is arranged between the thrust shoe 22 and the bearing seat 1 and is used for adjusting the gap between the thrust shoe 22 and the rotating shaft 3. As shown in fig. 4, when the adjusting member 420 is pushed to move downward, the inclined surface 410 on the supporting portion 412 pushes the adjusting member 420 to move leftward, and the adjusting member 420 pushes the thrust tile 22 to move leftward, so as to reduce the gap between the thrust tile 22 and the rotating shaft 3. It will be appreciated that the direction of inclination and the magnitude of the slope of the ramp 410 at the thrust shoe 22 also affect the adjustment of the thrust shoe 22 and will not be described in detail herein.

In the adjusting mechanism 4 at the thrust shoe 22, in conjunction with fig. 1,2, and 4, the adjusting end of the adjusting screw 4210 is located at an end of the adjusting screw 4210 away from the center line of the rotation shaft in the radial direction of the rotation shaft, so that the operator can rotate the adjusting screw 4210 to adjust the adjusting mechanism 4.

The adjustment mechanism 4 may be provided at the slide bearing bush 2 to be adjusted according to actual conditions on the basis of comprehensively considering factors such as cost and process.
