The retaining ring is now used as a kind of parts with a wide range of blocking and fixing effects, and I believe many people have seen it. Because of its high strength and hardness, the retaining ring is loved by people from all walks of life. Therefore, the classification of the retaining ring is also various. Let’s let the Jiangxi Kaixu retaining ring manufacturer take you to have a look!
One: Overview of the retaining ring
The retaining ring mainly plays the role of axial fixation, in which the conical surface with the retaining ring fixed has a higher degree of centering. Retainer is generally used for axial positioning, shaft retainer, hole retainer, opening retainer, etc., the general material 65Mn is used more, mainly used for parts fixing, prevent chaos, retainer has high strength, hardness, elasticity and other characteristics, in the market there are various kinds of retainer, flat retainer, inclined retainer, middle retainer, etc. The fixed position of the parts is also relatively different and different specifications. Retainer is a widely used carbon spring steel, compared with 65 steel, with higher strength, hardness, elasticity and hardenability, critical quench diameter in water is generally 30~50mm, oil is generally 16-32mm, heat treatment has overheating sensitivity and tempering brittleness tendency, easy to crack when water quenching, generally use oil quenching, retainer section size >80 suitable for water quenching oil cooling: The cutting property is good after annealing, but the cold deformation plasticity is low and the welding property is poor. The retainer ring is generally used after quenching and tempering at medium temperature.
Two: the classification of the retaining ring
1. Stop rings are classified according to their functions
Flat ring: A detachable essentially flat washer whose inner or outer part is used as a guard for the outer or inner ring of a centripetal cylindrical roller bearing.
Inclined retaining ring: a detachable ring with an “L” shaped section, the outer part of which acts as the inner retaining edge of a centripetal roller ball bearing.
Middle stop ring: A separable ring in two or more rows of roller bearings, used to separate and guide the rows of rollers. The retaining edge is a narrow shoulder parallel to the rolling direction and protruding the raceway surface, which is used to support and guide the rolling body and keep it in the bearing.
2. Detailed classification of stop rings
Retainer has: taper pin lock retainer, screw lock retainer, screw lock retainer with lock ring, steel wire retainer, elastic retainer with hole type A, elastic retainer with hole type B, elastic retainer with shaft type A, elastic retainer with shaft type B, screw fastening shaft end retainer, bolt fastening shaft end retainer, wire retainer with hole, wire retainer with shaft, etc.
Three: the purpose of the retaining ring
The fixing of shaft parts is divided into axial fixing and circumferential fixing. Axial fixation methods include: shaft shoulder or shaft ring fixation, shaft end retaining ring or conical surface fixation, shaft sleeve fixation, circular nut fixation, elastic retaining ring fixation. The retaining ring mainly plays the role of axial fixation, in which the conical surface with the retaining ring fixed has a higher degree of centering. The retaining ring of the rolling bearing is equivalent to an active retaining edge, which is used to file the roller for convenient installation. The structure of the retaining ring includes the flat retaining ring, the inclined retaining ring and the middle retaining ring.
