Embodiment 1

[0017] Embodiment 1: The structure for preventing the pull-off of the shaft mainly includes the fixed end ball cage 1, the star sleeve 2, the star sleeve spline 2-1, the star sleeve retaining ring groove 2-2, the shaft rod 3, Shaft spline 3-1, shaft circlip groove 3-2 and circlip 4, the other end of the fixed end ball cage 1 is fixedly connected to the star sleeve 2, and the star sleeve 2 is provided with a star sleeve flower The key 2-1 and the star sleeve spline 2-1 are provided with a star sleeve retaining ring groove 2-2, and the shaft 3 is inserted into one end with a shaft spline 3-1, and the shaft spline 3 -1 is provided with a shaft circlip groove 3-2, and the shaft circlip groove 3-2 is stepped, and the assembly sequence is that the circlip 4 is first loaded into the shaft circlip groove 3-2, and the shaft spline After 3-1 is centered with the star sleeve spline 2-1, force is applied to the shaft 3 along the axial direction, and the circlip 4 is squeezed under the act...

Embodiment 2

[0018] Embodiment 2: on the basis of embodiment 1, as figure 1 with figure 2 As shown, the first end surface 3-2-1 of the shaft clamp spring groove 3-2 is flat, and the second end surface 3-2-2 has a step. Adopting the structure of the shaft rod retaining ring groove, the processing is simple, and the cost is also roughly unchanged.

Embodiment 3

[0019] Embodiment 3: on the basis of embodiment 1, as image 3 As shown, the first end surface 2-2-1 of the star sleeve retaining ring groove 2-2 has an oblique angle, and the second end surface 2-2-2 is a straight surface. The structure of the retaining ring groove of the star sleeve remains unchanged, avoiding the duplication of the processing procedure.

Abstract

The invention discloses a structure capable of preventing a shaft rod from being pulled out. The structure mainly comprises a fixed end ball cage, a starlike sleeve, a starlike sleeve spline, a starlike sleeve jump ring groove, the shaft rod, a shaft rod spline, a shaft rod jump ring groove and a jump ring. The other end of the fixed end ball cage is connected with the starlike sleeve. The starlike sleeve spline is arranged in the starlike sleeve, and the starlike sleeve jump ring groove is arranged on the starlike sleeve spline. The shaft rod spline is arranged at the inserted end of the shaft rod. The shaft rod jump ring groove is arranged on the shaft rod spline and is in a step shape. According to the assembly sequence, the jump ring is firstly mounted in the shaft rod jump ring groove, after the shaft rod spline is aligned to the starlike sleeve spline, force is applied to the shaft rod in the axial direction, elastic deformation of the jump ring restores, and the jump ring is exactly clamped in the starlike sleeve jump ring groove and the shaft rod jump ring groove. The structure has the beneficial effects that the step-shaped jump ring groove is machined on the shaft rod spline, and therefore the shaft rod is not prone to being pulled out under the drawing situation; and through structural design to the shaft rod, stability and reliability of connecting of the shaft rodand the starlike sleeve are enhanced.

Description

technical field [0001] The invention relates to a connection structure between a shaft rod and a fixed joint, mainly a structure for preventing the shaft rod from pulling off. Background technique [0002] In the existing connection structure between the ball cage at the fixed end of the constant-velocity drive shaft and the shaft, there are ring grooves on the splines of the shaft and the splines of the star sleeve. In the circlip groove at the end, after the spline of the shaft rod is aligned with the spline of the star sleeve, the circlip is squeezed when the shaft rod is inserted. When the position of the circlip groove of the shaft rod and the circlip groove of the star sleeve are basically consistent , the circlip springs off, and falls into the circlip groove of the shaft rod and the star sleeve at the same time, playing the role of axial positioning. But this kind of circlip groove structure, in the case of a large axial pulling force, the circlip in the circlip gro...
