Reinforcement structure against heat deformation of electric motor bearing, comprises frame and rotor with axle box assigned to stator, where bearing is arranged in axle box and axle assigned to rotor is controlled by bearing

摘要

The structure comprises a frame (10) and a rotor (20), which has an axle box (14) assigned to a stator (12) and an opening at the free end. A bearing is arranged in the axle box and builds a space for holding an inner and an outer wall. The walls are connected with each other over a spacer. An axle (21) assigned to the rotor is controlled by the bearing. The bearing spacer has a recess (211) in the peripheral direction. A flange (212) encloses the axle ends facing the rotor and is blocked in the opening. The axle box and bearing are made of hard plastic.
