Abstract
The utility model discloses an overrun clutch spring location device which relates to the technical field of engineering machinery and comprises an output gear, a left blocking plate, a cam, a pin roller, a right blocking plate, an outer ring gear and a foldable spring. A groove with the height of H, the depth of L and an inclined angle at the opening tail end of alpha is arranged on the same side of the toothed portion of the cam, and one end of the foldable spring is fixed in the groove. Compared with the prior art, the overrun clutch spring location device prolongs service life of a spring, protects a rolling path face of an outer ring gear, and greatly improves reliability and durability of an overrun clutch.
Description
Technical field
The utility model relates to technical field of engineering machinery, particularly a kind of free wheel device spring-positioning device that is applied in the loader twin-turbine torque converter.
Background technique
At present, domestic 80% loader all adopts twin-turbine torque converter, twin-turbine torque converter and free wheel device co-operation; To gearbox input power; Can realize the switching between high speed light loading and low-speed heave-load automatically, increase work efficiency, reduce driver's labor intensity.
Existing no retainer free wheel device mainly includes output gear, right baffle-plate, cam, roller, right baffle plate, outer ring gear and folded spring; As depicted in figs. 1 and 2; When free wheel device is worked; Output gear drives the cam high speed rotating and cam drives the folded spring high speed rotating; Folded spring is outwards got rid of by centrifugal action under the high speed rotating situation and produces friction with the roller surface of outer ring gear, and this moment, the outer ring gear roller surface was easy to be folded spring 7 scratches and folded spring also is easy to rubbed by the roller surface of outer ring gear.
The model utility content
The utility model provides a kind of free wheel device spring-positioning device; The folded spring that it can solve the no retainer structure free wheel device that has now produces friction with the outer ring gear roller surface under the high speed rotating situation, the outer ring gear roller surface is prone to be folded spring scratch and the also easy problem that is rubbed by the roller surface of outer ring gear of folded spring.
In order to solve the problems of the technologies described above; The technological scheme that the utility model adopted is: it includes output gear, right baffle-plate, cam, roller, right baffle plate, outer ring gear and folded spring; Being provided with a height in the tooth portion side that all teeth of described cam contact with folded spring is that H, the degree of depth are that L, open end tilt angle are the groove of α, and said folded spring one end is fixed in the said groove.
In the technique scheme, scheme is more specifically: the height H of the groove that all tooth of said cam is set is that 10 mm～20mm, degree of depth L are that 1 mm～4mm, open end inclined angle alpha are 15 °～45 °;
Further: tooth that described cam is all and cam are one worker machine shaping.
Further: all teeth of described gear are on cam, to slot, and the root of each tooth is connected with the groove of cam.
Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect:
Because the same side in the tooth portion of cam is provided with a groove; Folded spring is fixed in this groove; Can prevent folded spring outwards got rid of by centrifugal action and produce friction with the outer ring gear roller surface; Thereby improve the working life of folded spring and protect the outer ring gear roller surface, thereby improved the reliability and the durability of free wheel device greatly.

Embodiment
Below in conjunction with the accompanying drawing instance, the utility model is done further to detail:
Embodiment 1 shown in accompanying drawing 3, accompanying drawing 4, accompanying drawing 5 and accompanying drawing 6; It includes output gear 1, right baffle-plate 2, cam 3, roller 4, right baffle plate 5, outer ring gear 6 and folded spring 7; Offering a height in the tooth portion side that all teeth 9 of cam contact with folded spring 7 is that 15mm, degree of depth L are that 2mm, open end inclined angle alpha are 15 groove 3-1; Folded spring 7 one ends are fixed in the groove 3-1, and this enforcement is that all teeth of described cam and cam are the structure of one worker machine shaping.
Embodiment 2 shown in accompanying drawing 7, accompanying drawing 8 and accompanying drawing 9; The all teeth of described gear are on cam, to slot; The root of each tooth is connected with the groove of cam; In the hole 8 that the cam race face has, carved tooth 9 in this hole, on tooth 9, having is that 2mm, open end inclined angle alpha are 15 groove 9-1 for 15mm, degree of depth L highly.
