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.
