Shock absorption shell structure for motor

Abstract

A shock absorption shell structure for a motor belongs to power machinery in the field of mechanical physic. Cooling fins are arranged on a surface of a metal outer shell, a metal inner shell is arranged in the metal outer shell and is separated from the metal outer shell, the metal inner shell and the metal outer shell are connected and fixed by a metal support piece, a partition cavity between the metal inner shell and the metal outer shell is filled with a plurality of shock absorption rubber blocks which are in close contact with the metal inner shell and the metal outer shell, and gaps are formed among the shock absorption rubber blocks. The metal inner shell is arranged in the metal outer shell of an existing motor by the metal support piece so as to form the partition cavity between the metal inner shell and the metal outer shell, heat dissipation cannot be affected, and shock transfer is reduced; the plurality of shock absorption rubber blocks are arranged in the partition cavity, the shock of the motor is absorbed to the greatest extent, and the shock generated by working of the motor is prevented from transferring outwards; and a ceramic layer is arranged on an inner wall of the metal inner shell, small holes are formed in the ceramic layer, and noise and a part of shock which are generated by rotation of an internal rotor can be absorbed.

Description

Technical field [0001] The invention belongs to a power machine in the field of mechanical physics, and specifically is a shock-absorbing shell structure for a motor. Background technique [0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses energized coils (that is, stator windings) to generate a rotating magnetic field and act on the rotor (such as a squirrel cage closed aluminum frame) to form a magneto-electric power rotating torque. Motors are divided into DC motors and AC motors according to different power sources. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (motor stator magnetic field speed and rotor rotation speed do not maintain synchronous speed). The motor is mainly composed of a stator and a rotor. The direction of the force movement of the energized wire in the magnetic field is related to the direction of the current and the direction of the magnetic ...

Problems solved by technology

[0004] In order to solve the problem that the existing motor casing cannot effectively reduce the vibration generated by the rotor during rotation, the present invention provides a shock-absorbing casing structure for a motor. The structure adopts a double-layer structure of the inner casing, and the two layers are Cavity, a shock-absorbing rubber block that can absorb vibration is set in the cavity, and a ceramic layer with a porous ceramic structure is set on the inner wall to absorb noise, thereby greatly reducing the vibration of the motor during operation
