What is a retaining ring

The retaining ring mainly plays an axial fixing role, with the cone surface and retaining ring having a higher centering degree. The retaining ring is generally used for axial positioning, with the main shaft equipped with a retaining ring, a hole equipped with a retaining ring, an open retaining ring, etc. Generally, 65Mn material is commonly used, with different specifications.
Elastic retaining ring is a useful carbon spring steel, which has high strength, hardness, flexibility, and hardenability compared to 65 steel. The critical hardening diameter in water is 30-50mm, and it is 16 and 32mm in oil. It is often sensitive to overheating and has high temper brittleness during heat treatment, and is prone to cracking during water quenching. Generally, oil quenching is used, and the suitable section size for water quenching oil is>80. Cold: After annealing, the cutting performance is good, but the cold deformation plasticity is low, and the welding performance is poor. This type of retaining ring is generally used after fire and medium temperature tempering.
