A high-reliability one-way device manufacturing method technical elements

Technical realization elements:

5. The purpose of the present utility model is to overcome the above technical shortcomings, provide a highly reliable unidirectional device, and solve at least one technical problem proposed in the background art.

6. In order to achieve the above technical objectives, the technical solution of the present invention provides a highly reliable unidirectional device, including:

7. Hollow shaft, said hollow shaft has adjacent first inner peripheral surface, second inner peripheral surface and first stepped surface at the connection position of said first inner peripheral surface and said second inner peripheral surface, so A first oblique spline is provided on the first inner circumferential surface, and the diameter of the first inner circumferential surface is smaller than the diameter of the second inner circumferential surface;

8. A drive shaft, the drive shaft having an adjacent first outer circumferential surface, a second outer circumferential surface, and a second stepped surface at the connection position of the first outer circumferential surface and the second outer circumferential surface, the first outer circumferential surface A second oblique spline is provided on the surface, the diameter of the first outer peripheral surface is smaller than the diameter of the second outer peripheral surface, the number of the second oblique splines is the same as the number of the first oblique splines, and the The second oblique spline can be slidably fitted with the first oblique spline, the first inner peripheral surface is slidingly sleeved on the first outer peripheral surface, and the diameter of the second outer peripheral surface is larger than the first inner peripheral surface A first annular groove is provided at one end of the first outer peripheral surface away from the second stepped surface, a wire retaining ring is clamped and fixed in the first annular groove, and the first stepped surface restricts the The wire retaining ring enters the area of the first inner peripheral surface.

9. Further, the high-reliability unidirectional device further includes a sleeve and a roller, one end of the sleeve is open, and the open end of the sleeve is sleeved on the hollow shaft, and the sleeve The enclosed shape between the inner peripheral surface of the hollow shaft and the outer peripheral surface of the hollow shaft

Into a plurality of accommodating grooves arranged in a circular array, each of the accommodating grooves includes a first connecting section and a second connecting section that are sequentially connected in the circumferential direction of the hollow shaft, and the thickness of the first connecting section Is smaller than the thickness of the second connecting section, the number of the rollers is multiple, and the plurality of rollers are built in the plurality of accommodating grooves in a one-to-one correspondence. When the rollers move closer to the first connection When the position of the section, the roller is in an interference fit with the accommodating groove, and when the roller moves to a position away from the first connecting section, the roller is in a clearance fit with the accommodating groove.

10. Further, the high-reliability unidirectional device further includes an elastic member, the elastic member is multiple, and the multiple elastic members are built in the multiple first connecting sections in a one-to-one correspondence, and each One end of the elastic member is connected to the roller.

11. Further, the high-reliability unidirectional device further includes an outer cover, and the outer cover is coaxially buckled with the open end of the sleeve.

12. Further, the high-reliability unidirectional device further includes a sealing gasket and a gasket, and the sealing gasket and the gasket are laminated and sandwiched between the outer cover and the open end of the sleeve.

13. Further, a gear shaft is fixed on the side of the sleeve away from the outer cover.

14. Further, a shift fork retaining ring is sleeved and fixed on the second outer peripheral surface.

15. Compared with the prior art, the beneficial effects of the present invention include at least: by designing a first annular groove at the end of the drive shaft and assembling a steel wire retaining ring, it plays a role of limiting, so that there is no need to reduce the inner shaft of the hollow shaft. The number of teeth of the spline improves the performance and reliability of the unidirectional device.
