Description

Technical Field

[0001] The utility model relates to the technical field of one-way wheels for automobile generators, in particular to a shock-absorbing one-way wheel for automobile generators. Background Art

[0002] The generator one-way pulley has the ability of one-way transmission, and its series of actions such as bouncing and reversing at the moment of starting do not generate transmission force; furthermore, its reverse rotation difference also does not generate current, which can effectively prevent it from damaging the vehicle motor, and it is also very obvious in reducing the reaction force on the engine, making the engine run smoothly. Furthermore, the generator one-way pulley can greatly reduce the runout of the belt during operation. The generator one-way pulley is also outstanding in reducing the tension vibration of the belt during operation, and the noise is also quite outstanding, which can significantly improve the service life of the generator system and its belt.

[0003] Existing automobile generator one-way wheels, such as a new one-way wheel that is easy to install and maintain disclosed in the utility model patent with publication number CN215861626U and a one-way wheel disclosed in the utility model patent with publication number CN216812592U, can all achieve one-way transmission.

[0004] However, it is found during use that the existing generator one-way wheel has a small contact area between the shaft core and the one-way needle roller shaft, and the contact area between the needle roller and the sleeve is small, which causes the generator one-way wheel to vibrate easily during operation, and makes the internal components of the generator one-way wheel easily collide with each other, increasing wear and tear, affecting the service life of the generator one-way wheel, resulting in poor practicality. Therefore, a shock-absorbing automobile generator one-way wheel is urgently needed to improve the above problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a kind of shock-absorbing automobile generator one-way wheel which locks the decagonal one-way needle roller bearing by the multi-faceted structure of the decagonal shaft core, and because the surface of the decagonal shaft core and the inner surface of the decagonal one-way needle roller bearing are closer to a circle, the combination of the decagonal shaft core and the decagonal one-way needle roller bearing is more firmly, and the mutual collision between the decagonal shaft core and the decagonal one-way needle roller bearing is reduced. At the same time, through the triangular structure of multiple groups of needle rollers, the arc surfaces of the multiple groups of needle rollers are more closely fitted to the bearing sleeve, and the mutual collision between the decagonal one-way needle roller bearing and the bearing sleeve is reduced, so that the automobile generator one-way wheel can run more smoothly and smoothly, and the service life of the automobile generator one-way wheel is extended.

At the same time, through the triangular structure of multiple sets of needle rollers, the arc surfaces of the multiple sets of needle rollers are more closely fitted to the bearing sleeve, reducing the mutual collision between the decagonal one-way needle roller bearing and the bearing sleeve, thereby making the one-way wheel of the automobile generator run more smoothly and extending the service life of the one-way wheel of the automobile generator.
