Apparatus For Blocking Foreign Substance Of Driving Dear For Railway Vehicle

摘要

The present invention relates to an anti-foreign matter prevention device for a railway vehicle speed reducer, and more particularly, to an anti-foreign matter prevention device for a railway vehicle speed reducer, which comprises a pair of dust covers which are coupled to a bearing housing, And a sealing unit which is fitted to the wiper ring and is closely attached to the axle so as to prevent inflow of moisture into the inside of the dust cover. The sealing unit is disposed outside the dust cover and disposed close to the axle, A support bracket coupled to an inner side of the support bracket for tight contact with the axle and coupled to the outer periphery of the axle shaft, And a second sealing portion for preventing foreign matter from entering between the axle and the wiper ring. Therefore, since the first sealing portion made of a rubber material is formed in a circular ring shape as compared with the conventional split type water inflow preventing structure, the inflow of water into the driving gear can be blocked more effectively, and the damage of the driving gear can be prevented .
