Abstract

The invention relates to an oil injection type double oil seal device which comprises an end cover, a pressure plate, a forced filling oil cup and oil seals, wherein the end cover is connected througha shaft which is supported between upper and lower box bodies through a bearing and is crimped and locked through the pressure plate; the end cover is in locking connection to the upper and lower boxbodies; the two oil seals which are axially and hermetically connected to the shaft are arranged on the inner wall of the end cover; an oil pressing channel is arranged on the upper part of the end cover; the outer port of the oil pressing channel is connected to the forced filling oil cup; and the inner port of the oil pressing channel corresponds to the oil seals. The oil injection type doubleoil seal device is simple in structure and prevents abrasion of the oil seals effectively, and the service life is prolonged and the sealing property is improved.

Description

technical field [0001] The invention relates to a sealing device of a reducer, in particular to an oil-injecting double oil sealing device. Background technique [0002] The transmission and rotation of the transmission shaft of the reducer will use an oil seal device to avoid oil leakage. However, in the prior art, during the rotation of the shaft, an oil seal or a sealing ring structure is used alone, and its sealing effect is poor. Oil hazard. Contents of the invention [0003] The invention provides an oil injection type double oil seal device with simple structure, which can effectively prevent oil seal wear and improve service life and sealing performance. [0004] The technical solution adopted in the present invention is: an oil injection type double oil seal device, which is characterized in that it includes an end cover, a pressure plate, an oil injection cup and an oil seal. The pressure plate is crimped and locked, and the end cover is locked and connected to...
