| description | The invention discloses a bearing configuration structure of a permanent magnet traction motor, which comprises a rotating shaft, a bearing pressed on the rotating shaft and an end cover which is fixed with a motor base and sleeved on the rotating shaft, and is characterized in that the end face of the bearing is provided with an oil storage cavity for storing lubricating grease, a gap sealing structure is formed between the end cover and the bearing to seal the oil storage cavity, the end cover is provided with a grease supplementing channel used for supplementing lubricating grease, and the grease supplementing channel is communicated with the oil storage cavity. According to the invention, loss of lubricating grease is reduced through the gap sealing structure, pollutants are prevented from entering the sealing structure, multi-stage non-contact labyrinth sealing structures on the two sides of an existing bearing are simplified into the gap sealing structure, the lubricating and sealing requirements of the |
