Abstract

The invention provides a split-type motor cover, and can solve the technical problem that a whole motor cover needs to be changed after an insulating layer in a bearing housing is fallen off in the prior art. The split-type motor cover comprises a cover body, and is characterized in that the cover body is of a barrel structure with openings in two ends. The split-type motor cover also comprises an upper cover plate, a bearing seat and a lower cover plate, wherein an upper through hole matched with an axle hole of the bearing seat is formed in the upper cover plate, a lower through hole matched with a mounting cavity of the bearing seat is formed in the lower cover plate, the upper cover plate and the lower cover plate are arranged at the upper end and the lower end of the cavity of the cover body in a threaded manner respectively, and the bearing seat is fixed into the cavity of the cover body through the upper cover plate and the lower cover plate in a press fitting manner; the bearing seat comprises an outer sleeve, an inner sleeve and an annular overturning edge extending inwards from the position of an opening in the upper end of the inner sleeve, and the outer sleeve is arranged on the inner sleeve in a sleeving manner and is in threaded connection with the inner sleeve.

Description

technical field [0001] The invention relates to the field of motors, in particular to a split motor cover. Background technique [0002] The existing motor cover has a bearing room in the middle, and the bearing room is used to install the bearing, but this kind of motor cover lacks the design to prevent the shaft current, and the shaft current is easy to form between the motor cover, the bearing and the rotating shaft, and the shaft current will seriously affect the motor. The service life of bearings and motors, there are potential safety hazards during use, and the reliability is low. Some motor covers have an insulating layer formed by injection molding on the inner wall of the bearing chamber to prevent the generation of axial current. However, after long-term use, the insulating layer is easy to fall off, and the entire motor cover needs to be replaced, and the replacement cost is relatively high. Contents of the invention [0003] In view of the above problems, the...
