Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a steel plate stamping combined motor flange end cover. Background Art

[0002] The motor end cover is a fixed part used to connect the motor housing and other transmission components.

[0003] Most of the existing motor end covers are traditional gray iron castings or aluminum alloy die-castings, with large machining allowances. They are usually completed through rough and fine secondary machining. The processing cycle is long, and the castings have high energy consumption, which makes it difficult to meet the requirements of industrial automation mass production and energy conservation and emission reduction.

[0004] In addition, some motor end covers produced by our company previously had relatively complex structures, so we designed and produced a new steel plate stamping combined motor flange end cover. Utility Model Content
