Problems solved by technology

[0003] The existing circlips for shafts are relatively simple in design, and the circlips are not fixed tightly enough in the shaft groove. When the circlips for shafts receive repeated radial impact loads, they are prone to loosening, which affects the use of the circlips.

specific Embodiment approach

[0014] figure 1 Show a specific embodiment of a stable shaft circlip according to the present invention: the stable shaft circlip includes a C-shaped circlip body 1, and both sides of the gap of the circlip body 1 are provided with pliers holes 4, and the circlip body 1 is provided with a layer of inner liner 3 on the inner wall. A C-shaped reinforced spring frame 2 is fixed outside the circlip body 1, and the reinforced spring frame 2 and the circlip body 1 are in the same plane.

[0015] like figure 1 As shown, both the circlip body 1 and the reinforcing spring frame 2 are made of spring steel with good elasticity, and the circlip body 1 and the reinforcing spring frame 2 are integral structures. The two pliers holes 4 on the circlip body 1 are circular through holes with the same size. You can use the circlip pliers to insert the jaws into the pliers holes 4, expand the circlip body 1, and put the circlip body 1 into the in the shaft groove. The inner liner 3 is made of...

Abstract

The invention discloses a stable snap spring for a shaft and relates to the field of machine parts. The two sides of a notch of a snap spring body of the stable snap spring for the shaft are providedwith pliers holes. The inner wall of the snap spring body is provided with a layer of inside liner. The exterior of the snap spring body is fixedly provided with a C-shaped reinforcing spring frame. The reinforcing spring frame is clamped to the exterior of the snap spring body and can effectively enhance the clamping force of the snap spring body. By means of the inside liner, the friction forcebetween the snap spring body and a shaft groove is increased, and the snap spring body is prevented from being loosened in the shaft groove.

Description

technical field [0001] The invention relates to the field of mechanical parts, in particular to a stable spring for a shaft. Background technique [0002] The shaft circlip is a mechanical part installed on the grooved shaft and used to move the hole to the fixed part. The inner diameter of the circlip for the shaft is slightly smaller than the assembly shaft diameter. When installing the circlip for the shaft, you must use the circlip pliers, insert the pliers mouth into the pliers hole of the retaining ring, expand the retaining ring, and then put the circlip for the shaft into the shaft groove. [0003] The existing circlips for shafts are relatively simple in design, and the circlips are not fixed fast enough in the shaft grooves. When the circlips for shafts receive repeated radial impact loads, they tend to loosen and affect the use of the circlips. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a stable...
