Apparatus for protection oil seal of carrier for differential device

摘要

The present invention relates to an oil seal protection device of a carrier for a differential device, wherein oil filled in the hollow hole 8 of the carrier 1 when the drive shaft 6 is rotated is inclined by an inclined surface of the shaft protrusion 11. The flow is directed to the upper portion of the lip portion 9a of 9), so that the oil does not directly press the lip portion 9a of the oil seal 9, and the oil of the drive shaft 6 and the oil seal 9 The gap 10 between the lip portions 9a also prevents foreign matters from being caught, thereby improving the durability and airtightness of the oil seal 9 and increasing the service life of the oil seal 9. The oil leakage can be eliminated.;Differential, Carrier, Oil Seal, Drive Shaft
