Description
Technical field
It the utility model is related to technical field of mechanical transmission, and in particular to a kind of new torque arm formula one-way clutch.
Background technology
The effect of one-way clutch is certain element is rotated by certain direction, in the other directions locking, can
It is divided into roller-type overrunning clutch and free wheeling sprag clutch two types.One-way clutch structure is similar to a bearing,
It is made up of outer ring, retainer, inner ring, voussoir or roller, the mutual rotation of Internal and external cycle is to rub to transmit by voussoir, when by outer
Power is impacted, wherein any voussoir or roller generation fatigue fracture all can be stuck, and is caused the continuously multiple fractures of voussoir or roller, is caused
Prevent Internal and external cycle from mutually rotating, can not passing power, and voussoir or roller can not be repaired, and cause one-way clutch integrally to report
It is useless.When roller-type one way clutch works, the contact position in roller and inside and outside circle occurs for Max.contact stress, strictly, by
Active force in roller both sides is equal, and the contact area on itself and inner ring convex surface is less than the contact area with outer ring concave surface,
So Max.contact stress occurs on contact surface of the roller with inner ring, therefore, roller-type one way clutch is most incident
It is Surface fatigue wear, typical failure mode is that spot corrosion is peeled off, similarly, and when free wheeling sprag clutch works, voussoir damage
Afterwards, one-way clutch global failure is caused to scrap.
Traditional one-way clutch is in reciprocal and intermittently-driving, under impact force action, especially heavy load when, unidirectionally
The roller of passing power or voussoir fatigue damage inside clutch and cause one-way clutch to fail, cause it is overall scrap, influence
Production line is worked continuously, and renewal cost is expensive.Therefore, it is low to develop a kind of cost, manufacture is easy, and maintenance is easy, dress
With simple, and the single accessory of manufacture can be repaired, so as to recover the new torque arm formula one-way clutch of whole one-way clutch function
It is desirability.
Utility model content
The purpose of this utility model is to provide a kind of cost low, and manufacture is easy, and maintenance is easy, and assembling is simple, and can tie up
The single accessory of manufacture is repaiied, so as to recover the new torque arm formula one-way clutch of whole one-way clutch function.
The purpose of this utility model is achieved in that the utility model includes torque arm, is fixedly mounted on transmission by key
On axle and ratchet and transmission device with ratchet, transmission device include pawl axis, coordinated and on pawl axis with ratchet
Ratchet, small axle and the torsionspring being sleeved on pawl axis, torsionspring one end is fixed on ratchet, and the other end is overlapped on small
On axle, pawl axis and small axle are fixedly mounted in torque arm.
Further, the endoporus of ratchet is circle.
Further, the endoporus of ratchet is square.
Further, using the radial central axis of ratchet as axis, the symmetric position of torque arm is provided with supporting plate, torque arm and branch
It is provided with that middle thick two is thin and the threaded strut in two between fagging, between torque arm and power transmission shaft, supporting plate and power transmission shaft
Between bearing is installed, the transparent cover of fixing bearing is installed in torque arm and supporting plate.
Further, the quantity of strut is 3.
Further, torque arm right side opening is provided with connecting hole, and bushing is provided with connecting hole.
The utility model, as the tumbler between power transmission shaft and torque arm, is avoided traditional using click structure
Roller or voussoir fatigue damage and the situation that causes one-way clutch global failure and scrap occurs, can repair that manufacture is single to match somebody with somebody
Part, so as to recover the function of one-way clutch, it can avoid can't buy matching because load is limited according to the size Aided design of load
Product, cost is low, and manufacture is easy, and maintenance is easy, and assembling is simple, may extend in heavy load, intermittent drive device systems
Use, according to power and torque size is transmitted, adjust each accessory size, form series of products, there is significant economic value and society
It can be worth.

Embodiment
The utility model is further described below in conjunction with the accompanying drawings, but the utility model is not subject in any way
Limitation, any changes and modifications made based on the utility model training centre, belongs to the scope of protection of the utility model.
As shown in Fig. 1~2, the utility model includes torque arm 8, is fixedly mounted on by key 14 on power transmission shaft 9 and carries spine
The ratchet 1 and transmission device of tooth, transmission device include pawl axis 3, the ratchet 2, small for coordinating and being arranged on pawl axis 3 with ratchet
Axle 7 and the torsionspring 4 being sleeved on pawl axis 3, the one end of torsionspring 4 are fixed on ratchet 2, and the other end is overlapped on small axle 7
On, pawl axis 3 and small axle 7 are fixedly mounted on 8 in torque arm, and the profile of ratchet 2 designs according to locus, in theory stress point phase
It is tangential direction to the center of circle of ratchet 1, is：90 ° of directions, actually design are adjusted to 93 °, increase intensity by adjusting component,
According to be actually needed the endoporus of ratchet 1 can be processed as it is circular or square with keyway.
Using the radial central axis of ratchet 1 as axis, the symmetric position of torque arm 8 is provided with supporting plate 13, torque arm 8 and supporting plate
Centre is provided between 13, and slightly two is thin and the threaded strut 12 in two, the quantity of strut 12 can be 3, torque arm 8 and power transmission shaft 9
