A brief introduction to the retaining ring

As the name suggests, a retaining ring is a coil that plays a fixing role, mainly used for fixing parts to prevent tampering. The retaining ring has high strength, hardness, elasticity, and other characteristics. The following is a brief introduction to the classification and use of retaining rings.

Classification of retaining rings

Flat retaining ring: A separable, essentially flat washer whose inner or outer part serves as the outer or inner ring edge of a radial cylindrical roller bearing. Diagonal retaining ring: with" L" A separable ring with a shaped cross-section, whose outer part acts as the inner edge of a radial roller ball bearing. Middle retaining ring: A separable ring in two or more rows of roller bearings, used to separate and guide each row of rollers. A rib is a narrow shoulder parallel to the rolling direction and protruding from the surface of the raceway, used to support and guide the rolling element and keep it inside the bearing.

Detailed classification

Retaining rings include: cone pin locking retaining ring, screw locking retaining ring, screw locking retaining ring with locking ring, steel wire retaining ring, hole elastic retaining ring - A type, hole elastic retaining ring - B type, shaft elastic retaining ring - A type, shaft elastic retaining ring - B type, screw fastening shaft end retaining ring, bolt fastening shaft end retaining ring, hole steel wire retaining ring, shaft steel wire retaining ring, etc.

Purpose of retaining ring

The fixation of components on the shaft is divided into axial fixation and circumferential fixation. The methods of axial fixation include: shoulder or collar fixation, shaft end retaining ring or conical surface fixation, shaft sleeve fixation, round nut fixation, and elastic retaining ring fixation. The retaining ring mainly serves as an axial fixation, with the conical surface fixed by the retaining ring having a high degree of centering. The retaining ring of a rolling bearing is equivalent to a movable edge, which is used to block the rollers and is convenient for installation. The structure of the retaining ring includes a flat retaining ring, a diagonal retaining ring, and a middle retaining ring.
