AI Technical Summary
Existing shaft retainers are prone to coming out of the retainer groove under high speed and large impact load, leading to transmission mechanism failure.
A limiting ring and a retaining ring for holes are installed on the rotating shaft. The limiting ring restricts the radial deformation of the retaining ring for the shaft, and the retaining ring for holes restricts the axial disengagement of the limiting ring, thus forming a multi-layer locking structure.
It effectively prevents the shaft retaining ring from loosening under high speed and large impact, thus improving the reliability of the transmission mechanism.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of transmission technology and relates to a locking structure suitable for shaft retaining rings. Background Technology
[0002] In transmission mechanisms, when space is limited, shaft retaining rings are often used to secure parts on the shaft to restrict their axial movement. For example... Figure 1 As shown: Existing structures mostly involve installing a shaft retainer 2 on the rotating shaft 1 to restrict the axial movement of the bushing-type parts 3.
[0003] When only a retaining ring is installed on the rotating shaft to secure the parts on the shaft, it can be used normally under conditions of low speed and small impact. However, when the rotating shaft rotates at a high speed and is subjected to a large impact load, the retaining ring is prone to coming out of the retaining ring groove due to the large centrifugal force, leading to the failure of the transmission mechanism. Utility Model Content
[0004] The purpose of this invention is to provide a shaft retaining ring locking structure, which can effectively prevent the shaft retaining ring from coming loose from the rotating shaft, thereby improving the reliability of the transmission mechanism.
[0005] The solution adopted in this utility model is as follows:
[0006] A locking structure for shaft retaining rings includes a shaft retaining ring 2, a limiting ring 3, and a hole retaining ring 4. A shaft retaining ring mounting groove is machined on a rotating shaft 1. The limiting ring mounting groove is located on a bushing-type part 5, outside the shaft retaining ring mounting groove and flush with it. The hole retaining ring mounting groove is located outside the limiting ring mounting groove, and its left end face is flush with the right end face of the limiting ring mounting groove. The shaft retaining ring 2 is installed in the shaft retaining ring mounting groove on the rotating shaft 1, and the limiting ring 3 and the hole retaining ring 4 are respectively installed in the limiting ring mounting groove and the hole retaining ring mounting groove.
[0007] The bushing-type part 5 is mounted on the rotating shaft 1 via splines or a mating relationship.
[0008] The circlip 2 is installed in the circlip mounting groove on the rotating shaft 1 to restrict the axial movement of the bushing-type part 5.
[0009] The limiting ring 3 is installed in the limiting ring groove of the bushing part 5 to limit the radial deformation of the shaft retaining ring 2.
[0010] A retaining ring 4 is installed in the retaining ring groove on the bushing part 5 to restrict the axial disengagement of the limiting ring 3, thereby indirectly restricting the disengagement of the retaining ring 2.
[0011] The effect of this utility model
[0012] The present invention provides a locking structure for shaft retaining rings. Without increasing the axial space of the transmission mechanism, it modifies the local structure of the bushing-type parts and installs a limiting ring and a retaining ring for the hole to limit the radial deformation of the shaft retaining ring. This achieves the purpose of preventing the shaft retaining ring from loosening during use due to excessive rotational speed of the rotating shaft and large impact, thereby improving the reliability of the transmission mechanism.
