Manufacturing method of high-reliability unidirectional device

The utility model discloses a high-reliability unidirectional device, comprising: a hollow shaft, the hollow shaft has an adjacent first inner peripheral surface, a second inner peripheral surface, and is located between the first inner peripheral surface and the The first stepped surface at the connection position of the second inner circumferential surface, the first inner circumferential surface is provided with a first oblique spline, and the diameter of the first inner circumferential surface is smaller than the diameter of the second inner circumferential surface; A drive shaft, the drive shaft having an adjacent first outer circumferential surface, a second outer circumferential surface, and a second stepped surface located at the connection position of the first outer circumferential surface and the second outer circumferential surface, and the first outer circumferential surface A second oblique spline is provided, the diameter of the first outer peripheral surface is smaller than the diameter of the second outer peripheral surface, and the number of the second oblique splines is the same as the number of the first oblique splines. The part is designed with a first annular groove, equipped with a steel wire retaining ring, which plays a limiting role, so there is no need to reduce the number of teeth of the spline in the hollow shaft, and improve the performance and reliability of the unidirectional device
