Description

High-strength check ring Technical Field The utility model relates to the technical field of check rings, in particular to a high-strength check ring. Background The retainer ring is also called a snap spring and is divided into a retainer ring for a hole and a retainer ring for a shaft, and has an axial limiting function and can prevent other parts from axially moving, wherein the flat retainer ring is a separable basically flat washer, and the inner part or the outer part of the flat retainer ring is used as an outer ring or an inner ring flange of the centripetal cylindrical roller bearing. For example, the name of the authorized bulletin number CN214424864U is an anti-channeling high-strength automobile check ring, the heat transfer to the check ring is reduced through the mutual staggered installation of the front clamping block and the rear clamping block, the check ring is prevented from being expanded with heat and contracted with cold to influence the normal use of the check ring, the check ring is also more tightly attached to the pin shaft, the pin shaft is clamped more stably through the ratchet teeth which are opposite to each other on the front ratchet tooth block and the rear ratchet tooth block, the inner supporting layer is arranged to be stainless steel, the outer check ring layer is matched with manganese steel, and the integral strength of the check ring is higher.
