Motor with bearing dismounting auxiliary device

Abstract

The invention discloses a motor with a bearing dismounting auxiliary device, and relates to the field of motor bearing dismounting. According to the structure of the device, an upper end cover and a lower end cover are located on the upper side and the lower side of a stator and a rotor respectively, the upper end cover and a center rotating shaft of the rotor are assembled into a whole through an upper bearing, and the lower end cover and the center rotating shaft of the rotor are assembled into a whole through a lower bearing; bearing bayonets on the inner sides of the upper end cover and the lower end cover are fixedly connected with the same detacher supports, the detacher supports are cylindrical, the inner diameter of each detacher support is matched with the size of an outer bearing seat of the upper bearing or the lower bearing, end plates of the detacher supports are provided with through holes matched with the diameter of a central rotating shaft, and a gap is ensured to be smaller than an air gap; a plurality of evenly distributed detacher connecting plates are fixedly connected to the periphery of the detacher support, an annular groove is formed in a central rotating shaft of the rotor, and a shaft check ring is installed in the annular groove. The device is simple in structure and does not appear or be used in other similar occasions, and the achieved functions greatly meet the actual requirements.

Description

technical field [0001] The invention relates to the field of motor bearing disassembly, in particular to a motor with a bearing disassembly auxiliary device. Background technique [0002] In the prior art, the disassembly of the original bearing requires the motor to be hoisted away from the working position, and the rotor needs to be disassembled with special tooling after the entire rotor is separated from the housing, which is time-consuming and labor-intensive, and also hits the bearing bayonet of the upper and lower end covers due to gravity. , it is easy to damage the end cap. In order to prevent damage to the bearing bayonet of the end cover when the motor bearing is disassembled, it is necessary to improve or redesign the overall installation or disassembly structure of the motor bearing. SUMMARY OF THE INVENTION [0003] In order to solve the problem that the process is complicated and the end cover is easily damaged when the motor bearing is disassembled, the pr...
