Abstract
The utility model relates to a jaw overdrive clutch for use in a pull operation mechanism, which is characterized in that a copper sleeve and a positioning flat key are arranged on an overdrive shaft; a driving claw and a driven claw are sheathed with the exterior of the copper sleeve, the overdrive shaft and the positioning flat key; one end of the driving claw and one end of the driven claw form sawtooth shape; the ends of the driving claw and the driven claw in a sawtooth shape can be engaged and can also be disengaged. A spring is sheathed with the end with concave plane of the driving claw; barrier sheets are sheathed with the top ends of the positioning flat key and the spring. The utility model has the advantages of simple structure, easy fabrication and low cost; compared with an overdrive bearing, the cost can be reduced about by 70%; when the utility model is used for the pull operation mechanism, the utility model can satisfy the slip requirement of an energy-storage shaft gear and a motor gear during manual energy storage.
Description
The utility model belongs to a kind of clutch, particularly a kind of castellated free wheel device of using in pull operation mechanism.
At present, in the pull operation mechanism of domestic production, the slip problem of energy storage shaftgear and generator shaft gear when realizing manual energy storage generally all adopts to surmount bearing and finish.Surmount the bearing accuracy height, general producer can not produce, and all needs outsourcing, and fetch long price also is difficult for having bought.And use and to surmount bearing and require also high other relevant element precision that cooperates.So make the entire equipment cost up.
The purpose of this utility model is to overcome deficiency of the prior art and provides a kind of and can satisfy the castellated free wheel device of using in the pull operation mechanism that job requirement also can reduce cost.
The purpose of this utility model can realize by following measure:
The structure of the castellated free wheel device of using in the pull operation mechanism is, end suit at the boss (2) that surmounts axle (1) copper sheathing (4), copper sheathing outside suit the passive pawl (6) of an end indention (5), surmount on the other end of axle and adorning location flat key (7), the outside suit that surmounts axle and location flat key the driving claw (9) of an end indention (8).During work, the zigzag fashion end of driving claw and passive pawl can be the mode of tooth embedding engagement, also can leave.Go up suit on the recessed plane of driving claw (10) and spring (11), the top suit of location flat key and spring catch (12).
The angle of tilt of driving claw or passive pawl serrated teeth is 100 °～170 ° or 80 °～10 °.
The utility model compared with prior art has following advantage:
1, the castellated free wheel device of the utility model is simple in structure, and it is low that the required precision ratio surmounts bearing, makes easily;
2, the castellated free wheel device cost of the utility model is low, approximately can reduce cost about 70% than surmounting bearing;
3, the moment of torsion that uses the part surmount bearing to transmit in pull operation mechanism is little, is about 100N.m, and rotating speed is very low, is about 10rpm.So when surmounting bearing and can satisfy manual energy storage fully with the replacement of castellated free wheel device, the slip requirement of energy storage shaftgear and motor gear.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the structural representation of the castellated free wheel device of the utility model;
Fig. 2 is the castellated free wheel device user mode of a utility model reference drawing.
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
The structure of the castellated free wheel device of using in the pull operation mechanism is, end suit at the boss (2) that surmounts axle (1) packing ring (3) and copper sheathing (4), copper sheathing outside suit the passive pawl (6) of an end indention (5), and the angle of tilt β of serrated teeth is 30 °.Surmount on the other end of axle and adorning location flat key (7), the outside suit that surmounts axle and location flat key the driving claw (9) of an end indention (8), and the angle of tilt α of serrated teeth is 150 °.During work, the zigzag fashion end of driving claw and passive pawl can be the mode of tooth embedding engagement, also can leave.Go up suit on the recessed plane of driving claw (10) and spring (11), the top suit of location flat key and spring catch (12).
During use, castellated free wheel device is installed in pull operation mechanism Central Plains the position that surmounts bearing is installed, be connected with pull operation mechanism by gear.Its action if driving claw (9) rotates along the location flat key clockwise, under the effect of pressure spring (11), makes driving claw (9) and passive pawl (6) be in engagement, by the Surface of action transmitting torque as shown in Figure 2.After driving claw stops operating, passive pawl is under the effect of manual energy storage plate (parts in the pull operation mechanism), clockwise rotate, because the ramp effect of serrated teeth (5), the power of transmission is P, on the inclined-plane, produce an end thrust PT, the pressure that this makes every effort to overcome the clothes pressure spring makes driving claw make axial rotation along location flat key (7), breaks away from fully up to driving claw and passive pawl, promptly finish slip, reach the purpose of overdrive clutch.After finishing an overdrive clutch action, driving claw is pushed ahead along the location flat key again under the effect of spring pressure clockwise, to mesh the action of beginning next cycle with passive pawl.
Claims (2)
1, the castellated free wheel device of using in a kind of pull operation mechanism, it is characterized in that: the end suit at the boss (2) that surmounts axle (1) copper sheathing (4), copper sheathing outside suit the passive pawl (6) of an end indention (5), surmount the axle the other end on adorning location flat key (7), the outside suit that surmounts axle and location flat key the driving claw (9) of an end indention (8), the zigzag fashion end of driving claw and passive pawl can be the mode of tooth embedding engagement, go up suit on the recessed plane of driving claw (10) and spring (11), the top suit of location flat key and spring catch (12).
2, according to the said castellated free wheel device of claim 1, it is characterized in that: the angle of tilt of driving claw or passive pawl serrated teeth is 100 °～170 ° or 80 °～10 °.
