Classification and use of elastic retaining ring industry solutions

What is the elastic retaining ring?

A circlip, also known as a retaining ring or buckle, belongs to a kind of fastener for installation in the machine, equipment, shaft groove, or hole groove and plays a role in preventing the axial movement of parts on the shaft or hole and retaining ring mainly has an axial fixed role, which taper plus retaining ring centering higher. The retaining ring is generally used for axial positioning, spindle with a retaining ring, hole with a retaining ring, open retaining ring, etc.; the general material 65Mn is used more, with different specifications. The elastic retaining ring is a valuable carbon spring steel, compared with 65 steel, with high strength, hardness, flexibility, and hardenability. Critical hardening in water diameter of 30 ~ 50mm, 16 and 32mm in oil, in the heat treatment is often overheating sensitivity. Tempering brittleness is large, water quenching is easy to crack, the general use of oil quenching, the appropriate water quenching and oil quenching retaining ring cross-section size of > 80 cold: after annealing, cutting performance is good, but cold Low deformation plasticity, poor welding performance. This retaining ring is generally used after fire and medium-temperature tempering.

 Retaining ring classification according to its function industry solutions

1. Flat retaining ring: a removable, basically flat washer, internal or external, used as the outer ring or inner ring of centripetal cylindrical roller bearings.

2. tilted retaining ring: a cross-section for the "L" shape of the removable retaining ring, its external as centripetal roller ball bearing inner retaining ring.

3. center ring: two or more rows of roller bearings in the separable ring, used to separate and guide the rows of rollers. The rim is a narrow shoulder parallel to the rolling direction and protruding from the raceway surface, which supports and guides the rolling elements and keeps them in the bearing.

4. Detailed classification: taper pin lock ring, screw lock ring, screw lock ring, steel ring, hole with elastic ring-A type, hole with elastic ring-B type, shaft with elastic ring-A type, shaft with elastic ring-B type, retaining ring, bolt fastening screw fastening shaft end ring, hole with steel ring, shaft with steel ring, and so on.

The use of elastic retaining ring industry solutions

The fixing of axial parts is divided into axial fixing and ring fixing. Axial fixing methods include shaft shoulder or shaft circle fixing, shaft end retaining ring or taper fixing, bushing fixing, round nut fixing, and elastic retaining ring fixing.

The retaining ring mainly plays the role of axial fixing, whose taper plus retaining ring centering degree is higher. The rolling bearing retaining ring is equivalent to a movable retaining edge, is used to file the roller, and is easy to install. The structure of the retaining ring has a flat retaining ring, oblique retaining ring, and retaining ring.

The primary role of an elastic retaining ring is to provide a specific flexible cushion between the connecting or fixing parts to dampen, cushion, and absorb vibration. It can be used in a variety of mechanical, electronic, and structural applications, and common uses include:

1. Shock absorption and vibration isolation: Elastomeric retaining rings can reduce the transmission of vibration and shock generated by mechanical equipment or structures during operation, thus reducing the impact of noise and vibration on the surrounding environment and other components.

2. Cushioning and protection: Elastomer retaining rings can provide cushioning and protection between connecting parts, preventing damage or loosening caused by thermal expansion, vibration, or shock.

3. Compensation and Adjustment: Elastomer retaining rings can compensate for imbalances or mismatches between connecting parts, allowing them to accommodate slight dimensional differences or variations.

4. sealing and waterproofing: some types of elastomer retaining rings also have a sealing function that prevents penetration or leakage of substances such as liquids, gases, or dust.

The selection of an elastomeric retaining ring should be determined by the specific application's needs, including factors such as the degree of elasticity required, durability, temperature range, and chemical resistance.
