Motor shell of vacuum pump

The utility model discloses a motor housing of a vacuum pump, which comprises a first housing, one end of the first housing is sleeved with a second housing, the outer wall of one end of the first housing is matched with the inner wall of the second housing, and the second housing is internally provided with an installation assembly. The mounting assembly is used for fixedly connecting the first shell with the second shell, a supporting column is fixedly connected to the bottom end of the first shell, and a damping assembly is arranged on the outer side of the supporting column. According to the motor shell of the vacuum pump, the first shell and the second shell are conveniently disassembled and assembled through the mounting structure, and then the working efficiency is improved; and when the vacuum pump works, the vacuum pump vibrates due to operation of the motor, vibration of the vacuum pump body is reduced through the damping assembly, and therefore parts in the vacuum pump are protected. 本实用新型公开了一种真空泵的
