Abstract

The invention discloses a motor insulated bearing chamber, and specifically relates to the field of motors. The motor insulated bearing chamber comprises a shell, wherein the shell is internally provided with a coupling, a driving shaft is arranged at one end of the coupling, a driven shaft is arranged at the end, which is away from the driving shaft, of the coupling, a front cover plate is arranged on the side, which is close to the driving shaft, of the shell, a rear cover plate is arranged on the side, which is close to the driven shaft, of the shell, first threaded holes are formed in thetwo sides of the shell, and second threaded holes are formed in the surfaces of the front cover plate and the rear cover plate. According to the invention, the coupling is arranged, the driving shaftand the driven shaft are inserted into two ends of the coupling, the rotating shaft is enabled to be insulated, the outer sides of the two ends of the coupling are both provided with bearings, the outer side of each bearing is provided with an insulating layer, the shell can be isolated from the bearings, the shell is enabled to be isolated from the bearings, and the insulating effect of the bearing chamber is improved. In addition, the front cover plate and the rear cover plate are fixedly connected with the shell through screws, the installation is convenient, parts are convenient to maintain and replace, the insulating layers are arranged in a honeycomb shape, heat dissipation is facilitated, and the motor performance can be improved.

Description

technical field [0001] The invention relates to the field of motors, and more specifically, the invention relates to an insulating bearing chamber for a motor. Background technique [0002] With the development of electronic application technology, frequency converter and its control technology are more and more widely used in motors, and it is inevitable that motors work on high-frequency power sources. High-order harmonics are difficult to eliminate, resulting in shaft current, which is very harmful to the bearing. When the motor has shaft current, the current will form a loop between the stator and rotor of the motor through the bearing. When the shaft current When passing through the bearing, the internal grease film will be broken down by the axial current, and over time, it will cause electrical corrosion to the grooves and rolling elements of the bearing, which will cause the bearing to run worse and worse, and the grease will dry up and heat up and burn the bearing, ...
