The elastic baffle ring for hole comprises a baffle ring matrix, which is characterized in that the outer edge of the baffle ring matrix for hole is provided with a thickening layer; The upper surface of the baffle ring is provided with an inner arc surface.

 

The manufacturing process is simple, the structure is reasonable, and the retaining ring has good elasticity. The original plane contact is changed to the internal arc contact, which effectively reduces the service stress of the fixed parts, thus making the fixing firm and positioning accurate. Moreover, the service life and working efficiency are improved by the design of thickening layer.

 

A device for mounting an elastic retainer for a hole comprises: Orientation, compression set and the push rod, guide the compression set of the outer diameter of aperture of the piston pump cylinder hole slightly smaller than braking points, oriented to the compression set of inner hole for the cone hole, the top diameter slightly larger than elastic relaxation condition of retaining ring diameter, the bottom diameter and the steps of the brake wheel cylinder cylinder hole diameter is equal, the steps of the push rod diameter is less than the brake wheel cylinder cylinder hole diameter, Greater than the inner diameter of the elastic retaining ring in the relaxed state.

 

When assembling, put the guide compression sleeve into the piston hole of the brake sub-pump cylinder block, and then put the hole into the upper end of the larger inner hole of the guide compression sleeve with the elastic ring, push the hole with the elastic ring to move down, when the hole with the elastic ring in the spring groove that spring open, the hole with the elastic ring spring into the spring groove after assembly; The device is simple in structure and ingenious in conception, which reduces the assembly difficulty of the elastic retaining ring, makes the assembly tend to be standardized, and improves the installation efficiency.
