What is a retaining ring
First, what is a retaining ring
Retaining ring mainly plays a role in axial fixation, in which the taper plus retaining ring centering degree is higher. 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 used more, with different specifications.
Elastic retaining ring is a useful 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 and 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 kind of retaining ring is generally used after fire and medium temperature tempering.
Second, retaining ring classification
1.According to its function
(1)flat retaining ring: a kind of removable, basically flat washer, its internal or external used as centripetal cylindrical roller bearing outer or inner ring.
(2)tilted retaining ring: a cross-section for the "L"shaped 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 is used to support and guide the rolling body and keep it in the bearing.
2.Detailed classification
Taper pin lock ring, screw lock ring, screw lock ring 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 shaft end ring, hole with steel ring, shaft with steel ring, and so on.
Third, the use of elastic retaining ring
The fixing of axial parts is divided into axial fixing and ring fixing. Axial fixing methods are: shaft shoulder or shaft circle fixed, shaft end retaining ring or taper fixed, bushing fixed, round nut fixed, elastic retaining ring fixed.
Retaining ring mainly plays the role of axial fixing, which taper plus retaining ring centering degree is higher. Rolling bearing retaining ring is equivalent to a movable retaining edge, used to file roller, easy to install. The structure of retaining ring has flat retaining ring, oblique retaining ring and retaining ring.
