Transmission Oil Seal Leak Rubber leak proof seals-Hongtai
As the core sealing component in mining machinery equipment, rubber oil seals for mining cars play an irreplaceable and critical role. Its main functions are reflected in two aspects: firstly, establishing a stable and reliable sealing barrier to ensure that lubricating oil or grease can be continuously and uniformly maintained inside the transmission system, preventing oil leakage along the rotating shaft or joint surface. Secondly, establish efficient protective barriers to effectively prevent dust, sediment, rock debris, and various corrosive impurities commonly present in the mining environment from entering the equipment interior, avoiding abrasive wear, pitting, or chemical corrosion caused by these hard particles or chemicals on key contact areas such as gear meshing surfaces and bearing raceways.

According to different structural forms, rubber oil seals for mining cars are mainly divided into two categories: skeleton free oil seals and skeleton oil seals.
The skeleton free oil seal structure is relatively simple, completely made of rubber material, with good flexibility and low requirements for the coaxiality of the installation holes. It can automatically compensate for installation deviations to a certain extent. Due to its overall elasticity, it can buffer some energy when subjected to impact or vibration, making it more suitable for use in areas with relatively mild working conditions, low rotational speeds, or limited axial space, such as some auxiliary transmission systems of mining cars or low-speed wheel edge sealing positions.
A skeleton oil seal is embedded with a metal skeleton (usually made of high-quality cold-rolled steel plate or corrosion-resistant alloy) in the inner or outer ring, significantly enhancing the overall rigidity and dimensional stability of the oil seal. This design enables it to withstand higher system pressures, faster axial linear velocities, and intense mechanical vibrations without deformation or loosening.

The metal skeleton also facilitates interference fit installation, making the oil seal more accurately and firmly positioned in the housing. Therefore, skeleton oil seals are commonly used in key areas such as the main transmission system, gearbox output end, and drive axle hub of mining cars, which require extremely high durability and impact resistance of the seals.
