Description
Technical field
The utility model belongs to a kind of free wheel device, specifically, particularly relates to the spring reset type overrunning clutch of a kind of loader band spring guide finger structure.
Background technique
The free wheel device used in prior art is primarily of input assembly and outer ring gear composition, and input assembly comprises the inner race on intermediate input axle, inner ring cam and inner ring cam.Described inner race is made up of the baffle ring of inner ring cam and both sides, is incorporated with roller in it, inner race inwall is offered at least one innerspring pin-and-hole.Due in use, roller moves in a circle together with input assembly, and it is movable that roller is contained in inner race, and in clutch process, roller moving back and forth on the external tooth of inner ring cam, makes spring be compressed frequently and extend.Due to the conical surface for being formed during boring bottom pin-and-hole that inner ring cam is offered, to the support of spring and guiding all poor, spring is easily damaged in compressing frequently and extending, finally causes overdrive clutch assembly failure.
Summary of the invention
In order to the spring solved in prior art in traditional free wheel device in inner ring cam easily damages, maintenance cost is higher, easily causes the defect of overdrive clutch assembly failure, and the utility model provides a kind of spring reset type overrunning clutch.
The utility model is achieved through the following technical solutions:
A kind of spring reset type overrunning clutch, comprise intermediate input axle and outer ring gear, inner ring cam is provided with between intermediate input axle and outer ring gear, inner ring cam edge is provided with external tooth, inner race between external tooth and outer ring gear is provided with the roller assembly be made up of roller and spring, in the pin-and-hole of spring fitting on inner ring cam; Be provided with guide finger in described pin-and-hole, spring housing is contained on guide finger.
Guide finger is provided with pin, and spring is located between pin and guide finger.
Compared with prior art, the beneficial effects of the utility model are:
The guide finger set up in pin-and-hole can play spring and better support and leading role, and reduce the risk of spring failure, reliability is higher, greatly reduces maintenance cost and practical cost, extends working life of the present utility model.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of spring reset type overrunning clutch, comprise intermediate input axle 1 and outer ring gear 4, inner ring cam 2 is provided with between intermediate input axle 1 and outer ring gear 4, inner ring cam 2 edge is provided with external tooth 5, inner race 7 between external tooth 5 and outer ring gear 4 is provided with the roller assembly be made up of roller 6 and spring 9, and spring 9 is arranged in the pin-and-hole on inner ring cam 2 and external tooth 5; Be provided with guide finger 10 in described pin-and-hole, guide finger 10 be set with successively spring 9 and pin 8.
The utility model, when making, is connect by baffle ring 3 phase shelves between intermediate input axle 1 with inner ring cam 2; External tooth 5 is provided with the roller 6 matched with it.
During use, roller 6 moves in a circle together with intermediate input axle 1 and inner ring cam 2, and move back and forth on the external tooth 5 of inner ring cam 2, in clutch process, roller 6 is by pin 8 extrusion spring 9 frequently, and spring 9 is because being sleeved on guide finger 10, and guide finger 10 pairs of springs 9 can serve and better support and leading role, greatly reduce the risk that spring 9 lost efficacy, extend working life of the present utility model; And it is also more convenient to change spring 9 when safeguarding.
