Traction motor and self-configured transportation protection locking mechanism thereof

The invention discloses a self-configuration transportation protection locking mechanism, which relates to the technical field of motors, and comprises a bearing mounted on a rotating shaft, an end cover mounted on an outer ring of the bearing, a bearing cover mounted on the outer end surface of the end cover, and a support ring axially and movably mounted on the outer end surface of the bearing cover, the outer oil seal annularly sleeves the rotating shaft and is mounted in the supporting ring, a first inclined surface is arranged on the inner wall surface of the supporting ring, a locking inclined surface matched with the first inclined surface is arranged on the outer edge of the outer oil seal, and an acute angle is formed between the first inclined surface and the axial direction of the rotating shaft. As the bearing cover, the support ring and the outer oil seal all belong to product components of the traction motor, switching between a transportation state and a working state of the traction motor can
