A circlip (also known as a circlip) is also called a snap ring or a snap ring. It is a kind of fastener, and it is installed in the shaft groove or hole groove of a machine or equipment to act as a stop for axial parts or axial parts. The role of sports.
Spring/Ring
The more commonly used are STW and RTW, the domestic mainland production mainly uses spring steel of 65MN. Of course, there are C-type E-type U-type springs.
It is divided into hole retaining ring and shaft retaining ring, which can prevent other parts from moving axially. The molding process mostly uses sheet metal punching, and the functional cross section is conical. After assembly, it is mostly “linear contact”. Some large size models use wire rod winding and forming, punching and cutting excess material, and the cross section is a regular rectangle. After assembling, it is “face”. contact".
Retaining ring: taper pin lock ring, screw lock ring, screw lock ring with lock ring, steel ring, hole with elastic ring -A type, hole with elastic ring -B type, axis With elastic ring-A type, shaft with elastic ring-B type, screw fastening shaft end retaining ring, bolt fastening shaft end retaining ring, hole steel wire retaining ring, shaft steel wire ring and so on.
The fixing of the parts on the shaft is divided into axial fixation and circumferential fixation.
Axial fixation methods are: shaft shoulder or collar fixed, fixed with a shaft end retaining ring or conical surface, fixed with a shaft sleeve, fixed with a round nut, fixed with a retaining ring.
The retaining ring is mainly used for the role of axial fixation, in which the conical surface plus the retaining ring has a high degree of centering.
The retaining ring of the rolling bearing is equivalent to a movable rib and is used for the roller to facilitate installation. The structure of the retaining ring is a flat retaining ring, an inclined retaining ring and a middle retaining ring.
