Reducer gearbox motor oil seal

The PQK oil seal of the reducer gearbox innovatively constructs a three-dimensional composite sealing system of "sealed + combined + labyrinth". Through fluid dynamics simulation, the cavity structure is optimized. With the independently developed rubber material formula library, it can precisely control the Shore hardness within the range of 70-90HA. While meeting the high wear-resistant requirements under high torque working conditions, it also takes into account the lightweight sealing design of small-sized gearboxes.

The product adopts the modular design concept and is suitable for all types of gearbox structures, such as circular arc worm gears, planetary cycloid gears, helical gears, and continuously variable transmissions. Certified by authoritative institutions, this oil seal can operate stably in a wide temperature range from -40°C to 200°C and has excellent compensation ability for shaft eccentricity at the level of 0.05mm. Its application scenarios cover the full power range from the main propulsion gearbox (10MW+) of ten-thousand-ton ships to the micro-precision gearbox (<1kW). It has been successfully used in supporting the automotive power transmission system, agricultural machinery gearboxes, irrigation equipment reducers and other fields, significantly improving the operational reliability of the equipment and reducing the maintenance cost.
