Floating oil seal ring is one of the important working components of the floating seal, which can float freely in the shell, so the impact on the density when the shaft rotates at high speed and vibration is small, and friction and wear are also small. The main reason is the wear resistance of the tool surface and the internal elasticity and plasticity of the floating oil seal ring. However, because the surface temperature of the floating oil seal ring cannot be lower than the standard temperature requirement, in order to improve its wear resistance, the hot forged oil seal ring needs to be quenched and tempered. The heated oil seal ring will produce uniform austenite, which improves its wear resistance.

There will be a carburized structure on the surface of the floating oil seal ring, so the choice of heating temperature is an important issue. The floating oil seal ring requires high manufacturing precision. The unevenness of the ring and the non-perpendicularity of the end surface and the surface roughness have obvious effects on the sealing performance. Impact. Choose the right and appropriate material for the surface treatment of the oil seal ring to effectively ensure the life of the oil seal ring.
