Abstract
The utility model discloses an axial one-way clutch which comprises a rotating body, wherein, a shaft is inserted into the rotating body; an inner shaft sleeve is closely matched on the outside of the shaft; a spring is arranged between the inner shaft sleeve and the rotating body; one end of the spring is a free end and the other end of the spring is a fixed end which is relatively fixed on the rotating body or the inner shaft sleeve. The utility model not only has simple structure but also can be clutched at any position and has large transmission torque, and can be used in high-speed movement situations.
Description
Technical field
The utility model relates to a kind of around the shaft type overrunning clutch.
Background technique
Clutch is the movement connecting mechanism between two parts, by " from " and " closing " two actions drive or stop the motion of another parts by parts.The structural type kind of clutch of the prior art is more, after common clutch needs operator to handle connected element, clutch just can break away from or close, and automatic clutch is certainly also arranged, for example ratchet mechanism, if it is in disengaged position when forward rotation, it is when counter-rotating so, and when ratchet turned over several angle, ratchet just can drive ratchet and rotate together, the clutch of this type major defect be the structure more complicated, and could move after will turning over several angle.
Summary of the invention
The utility model purpose is: provide a kind of around the shaft type overrunning clutch, this clutch is not only simple in structure, and at an arbitrary position can clutch, and the torque ratio of transmission is bigger, can be used for the high-speed motion occasion.
The technical solution of the utility model is: a kind of around the shaft type overrunning clutch, described clutch comprises solid of rotation, a rotating body is inserted with axle, the outer internal axle sleeve that closely cooperated of axle, be provided with spring between internal axle sleeve and the solid of rotation, one end of spring is a free end, and the other end is a fixed end, the fixed end relative fixed solid of rotation or internal axle sleeve both one of on.
The further technological scheme of the utility model is: a kind of around the shaft type overrunning clutch, described clutch comprises solid of rotation, a rotating body is inserted with axle, the outer internal axle sleeve that closely cooperated of axle, be provided with spring between internal axle sleeve and the solid of rotation, one end of spring is a free end, and the other end is a fixed end, the fixed end relative fixed solid of rotation or internal axle sleeve both one of on;
Described spring cooperates with internal axle sleeve, and the internal diameter of spring is more smaller than the external diameter of internal axle sleeve, and spring housing is on internal axle sleeve, and the fixed end of spring is fixed on the solid of rotation;
Described solid of rotation comprises belt pulley, and the external axle sleeve that closely cooperated on the inwall of belt pulley, spring are arranged between external axle sleeve and the internal axle sleeve, are provided with bearing between the belt pulley of external axle sleeve both sides and the internal axle sleeve;
Described internal axle sleeve closely cooperates by key and axle, axle is provided with position limit socket near a side of the insertion end of belt pulley, and position limit socket is spirally connected by the screw of bolt with axle, and position limit socket inwardly pushes against on key with the surface of contact of axle simultaneously, position limit socket is provided with a circle flange, and flange inwardly pushes against internal axle sleeve;
Described belt pulley is provided with case at the insertion end opening; The fixed end of described spring passes external axle sleeve and is fixed on the belt pulley.
The utility model advantage is:
1. the utility model is simple in structure, can both play clutch action at an arbitrary position.
2. the torque ratio of the utility model transmission is bigger, can be used for the high-speed motion occasion.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
Wherein: 1 solid of rotation; 11 belt pulleys; 12 external axle sleeves; 13 cases; 2; 3 internal axle sleeves; 4 springs; 41 free ends; 42 fixed ends; 5 bearings; 6 keys; 7 position limit sockets; 71 flanges; 8 bolts.
Embodiment
Embodiment: as shown in Figure 1, a kind of around the shaft type overrunning clutch, comprise solid of rotation 1, be inserted with axle 2 in the solid of rotation 1, the axle 2 outer internal axle sleeves 3 that closely cooperated, be provided with spring 4 between internal axle sleeve 3 and the solid of rotation 1, spring 4 cooperates with internal axle sleeve 3, and the internal diameter of spring 4 is more smaller than the external diameter of internal axle sleeve 3, spring 4 is enclosed within on the internal axle sleeve 3, one end of spring 4 is a free end 41, and the other end is a fixed end 42, and the fixed end 42 of spring 4 is fixed on the solid of rotation 1.
Solid of rotation 1 comprises belt pulley 11, and the external axle sleeve 12 that closely cooperated on the inwall of belt pulley 11, spring 4 are arranged between external axle sleeve 12 and the internal axle sleeve 3, are provided with bearing 5 between the belt pulley 11 of external axle sleeve 12 both sides and the internal axle sleeve 3.
Internal axle sleeve 3 closely cooperates by key 6 and axle 2, axle 2 is provided with position limit socket 7 near a side of the insertion end of belt pulley 11, position limit socket 7 is spirally connected by the screw of bolt 8 with axle 2, the surface of contact of position limit socket 7 and axle 2 inwardly pushes against on key 6 simultaneously, position limit socket 7 is provided with a circle flange 71, and flange 71 inwardly pushes against internal axle sleeve 3; Belt pulley 11 is provided with case 13 at the insertion end opening; The fixed end 42 of spring 4 passes external axle sleeve 12 and is fixed on the belt pulley 11.
When axle 2 (or internal axle sleeve 3) and solid of rotation 1 do not have when relatively rotating, the motion state of spring 4 is consistent with them; The right apparent time of Fig. 1, when solid of rotation 1 relatively axle 2 (or internal axle sleeves 3) be in when clockwise rotating, spring 4 is in relaxation state, internal diameter increases, spring 4 breaks away from axle 2; When solid of rotation 1 relatively axle 2 (or internal axle sleeves 3) be in when rotating counterclockwise, spring 4 is in the state of tightening, internal diameter dwindles, its frictional force with axle 2 increases suddenly, makes spring 4 drive axle 2 and rotates together.
In addition to the implementation, the utility model can also have other mode of execution.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
