Motor shell and manufacturing method thereof and motor

Abstract

The invention discloses a motor shell and a manufacturing method thereof, and a motor. The motor shell comprises a first shell and a second shell, wherein the second shell sleeves the inner side of the first shell, a plurality of spiral tooth ribs arranged along the axis of the first shell are arranged on the inner side wall of the first shell, a silencing groove is formed between every two adjacent spiral tooth ribs, a matching tooth rib matched with the corresponding silencing groove is arranged on the outer side of the second shell, one side of each matching tooth rib is attached to one side of the corresponding spiral tooth rib, and a damping medium is arranged between the other side of each matching tooth rib and the other side of the other spiral tooth rib. According to the invention, the spiral tooth ribs and the silencing grooves are matched to form a silencing bowl structure, the motor shell forms an integral structure with a silencer through the first shell, damping application of the motor in an integrated occasion is facilitated, excellent shock absorption capability is realized, the heat dissipation capability of the motor shell is also guaranteed, and the motor shellcan be applied to special motors.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to a motor casing, a manufacturing method thereof and a motor. Background technique [0002] The noise reduction and heat dissipation of the motor are important research directions for improving the performance of the motor. The noise reduction and shock absorption of the motor in the prior art are usually achieved by adding external structures, such as shock absorbing springs and shock absorbing rods. For example, in the Chinese patent literature, the authorized announcement number is CN210867399U, which was published on June 26, 2020, which is called a utility model patent for a shock absorbing motor. This application discloses a shock absorbing motor, including a motor body, and the motor The body is covered with a shell, and several shock absorbing assemblies are arranged between the inner wall of the shell and the outer wall of the motor body. The bottom of the motor body is con...

AI Technical Summary

Problems solved by technology

[0003] The disadvantage of the motor shock absorber in the prior art is that it needs an external expansion mechanism, which can only be used in occasions with low requirements for installation space, and its integrity is poor. The ability of motor shock absorption depends entirely on the external expansion mechanism, and it cannot be applied in a modular manner.
