Abstract
The utility model discloses a key-free connecting device for a roller of a drilling machine. The roller of the drilling machine is fixedly connected with a roller shaft sleeve, and the roller shaft sleeve is arranged on a shaft in a sleeved mode. The key-free connecting device for the roller of the drilling machine comprises a first locking disc 1, a second locking disc 2 and a locking ring, wherein the first locking disc 1, the second locking disc 2 and the locking ring are installed on the roller shaft sleeve, the locking ring has a certain thickness and is provided with an opening, the inner diameter of the locking ring is adaptive to the outer diameter of the roller shaft sleeve, and the middle of the outer wall of the locking ring contracts gradually towards the two ends, so that conical surfaces are formed; both the first locking disc and the second locking disc are annular, the two conical surfaces of the locking ring are sleeved with the first locking disc and the second locking disc respectively, and the shape of the inner wall of the first locking disc and the shape of the inner wall of the second locking disc are adaptive to the shapes of the two conical surfaces of the locking ring; the first locking disc and the second locking disc are fastened together through multiple locking bolts. According to the key-free connecting device for the roller of the drilling machine, due to the fact that the contact area between the shaft and the roller shaft sleeve is large, large torque can be transmitted, and both safety and reliability are guaranteed; due to the fact that fastening is achieved through the locking bolts, both disassembly and assembly are convenient.
Description
Technical field
The utility model relates to a kind of rig, particularly relates to a kind of rig cylinder without key connection set.
Background technique
Domestic petroleum rig, well repairing machine are all furnished with cylinder, drive traveling system realize the lifting of drilling tool and transfer by the rotation of cylinder.The roller sleeve of existing cylinder and axle mostly adopt interference fit, and flat key connects.This traditional Placement transmitting torque area is little, under heavy load, the effect of moment of torsion alternation fatiguability, wear and tear and roll key, cause cylinder and axle to send out spacious, and install, dismounting difficulty.
Summary of the invention
The purpose of this utility model is to provide that a kind of area of contact is large, transmitting torque is large, the rig cylinder of easy accessibility is without key connection set.
For this reason, the technical solution of the utility model is as follows:
A kind of rig cylinder is without key connection set, and described rig cylinder is fixedly connected with roller sleeve, and described roller sleeve is sleeved on axle, and this rig cylinder comprises the 1st locking plate, the 2nd locking plate and the locking ring that are arranged on described roller sleeve without key connection set.
Described locking ring has certain thickness and is formed with an opening, and the internal diameter of this locking ring and the external diameter of described roller sleeve adapt, and the middle part of its outer wall of locking ring forms the conical surface to two ends convergent;
Described the 1st locking plate and the 2nd locking plate are annular, are enclosed within respectively on two conical surfaces of described locking ring, and the shape of the shape of the 1st locking plate and the 2nd locking plate inwall and two conical surfaces of locking ring adapts; Described the 1st locking plate and the 2nd locking plate tighten together by multiple lock bolts.
In an embodiment of the present utility model, described lock bolt is evenly distributed with 4 at circumferencial direction.
Rig cylinder of the present utility model is without key connection set, and axle sleeve produces resiliently deformable under the effect of locking plate, by the frictional force transmitting torque of surface of contact radially, reaches cylinder and is reliably connected object with drum shaft.Because the surface of contact of drum shaft and axle sleeve is larger, thus can transmit compared with high pulling torque, and safe and reliable; Fastening owing to being undertaken by lock bolt, so dismounting is very convenient.
Brief description of the drawings
Fig. 1 is the structural representation of rig cylinder of the present utility model without key connection set.
Embodiment
Below in conjunction with accompanying drawing, rig cylinder of the present utility model is described without the structure of key connection set.
As shown in Figure 1, rig cylinder 7 is fixedly connected with cylinder axle axle sleeve 4, and cylinder axle axle sleeve 4 is sleeved on axle 5.Rig cylinder comprises the 1st locking plate the 1, the 2nd locking plate 2 and the locking ring 3 being arranged on roller sleeve 4 without key connection set.
Locking ring 3 has certain thickness and is formed with an opening, and the external diameter of the internal diameter of locking ring 3 and roller sleeve 4 adapts, and the middle part of self-locking ring 3 outer walls forms the conical surface to two ends convergent.The 1st locking plate 1 and the 2nd locking plate 2 are annular, be enclosed within respectively on two conical surfaces of described locking ring 3, the shape of the shape of the 1st locking plate 1 and the 2nd locking plate 2 inwalls and 3 two conical surfaces of locking ring adapts, and the 1st locking plate 1 and the 2nd locking plate 2 tighten together by multiple lock bolts 6.
In embodiment shown in the figure, described lock bolt 6 is evenly distributed with 4 at circumferencial direction.
Below the working principle of this device is described:
As shown in the figure, in the time tightening lock bolt 6, the 1st locking plate 1 and the 2nd locking plate 2 move in opposite directions along F, M direction under the pulling force of lock bolt 6.Because locking ring 3 is provided with slope, so the 1st locking plate 1 and the 2nd locking plate 2 form the pressure P of pointing to axle 5 under the effect on slope, force locking ring 3 radial contraction.Roller sleeve 4 produces radial elastic distortion under the effect of locking ring 3, thus extrusion axis 5.On the circumferential surface in the moving roller sleeve 4 coordinating and axle 5 connecting parts, because the effect of pressure P produces frictional force and transmitting torque.
On the contrary, while unclamping lock bolt 6, pressure P disappears, and roller sleeve 4 recovers moving cooperation under self flexible effect, thereby can take out like a cork axle 5.
