AI Technical Summary
Traditional floating oil seals, during long-term use, suffer from accelerated aging due to the heat transmitted by the transmission components, causing the sealing ring to be subjected to high temperatures. This leads to reduced stability and potential oil leakage.
Heat insulation rings are installed in the first and second annular grooves of the floating ring and are limited by limiting rings. Combined with heat-conducting rods distributed in an annular array, the heat dissipation performance is improved. At the same time, the use of wear-resistant rubber rings and limiting mechanisms facilitates the replacement of heat insulation rings and enhances the heat insulation and heat dissipation effect of the sealing ring.
It effectively reduces the heat impact of the sealing ring, extends the service life of the sealing ring, improves the stability of the floating oil seal, prevents oil leakage, and ensures long-term reliability of sealing performance.
