Embodiment

[0018] The circular chamber 8 of the shell 1 is used to install components such as rotors and coils. Several circles of steps 9 are concentrically arranged at the upper opening of the circular chamber 8. The outer diameter of the steps 9 gradually decreases from bottom to top, except Except for the uppermost step 9, the upper ends of the other steps 9 are all covered with sealing rings, and a matching upper cover is installed on the upper end of the shell 1. The upper cover has a water outlet and is protected by multi-layer sealing rings, which can effectively prevent cooling water passages from cooling. 6 of the water goes into the circular chamber 8 . The inner wall of the cooling water channel 6 is evenly arranged with several metal vertical bars 7, the metal vertical bars 7 can increase the strength of the cooling water channel 6, so that the thickness between the inner wall of the cooling water channel 6 and the outer wall of the casing 1 can be relatively thinner, reducin...

Abstract

The invention relates to a multi-layer sealed motor shell, which comprises a shell, wherein the middle of the upper end of the shell is provided with a circular chamber for accommodating a rotor and acoil; a circle of cooling water channel is concentrically arranged at the upper end of the shell around the circular chamber; a plurality of metal vertical strips are evenly arranged on the inner wall of the cooling water channel; the cooling water channel is communicated with a water inlet formed in the outer side of the shell; a plurality of circles of steps are concentrically arranged at an opening in the upper end of the circular chamber; the outer diameter of the steps is gradually decreased from bottom to top; and the upper ends of the steps except for the step at the top are sleeved with sealing rings. Under the protection of the multiple layers of sealing rings, water in the cooling water channel can be effectively prevented from entering the circular chamber.

Description

technical field [0001] The invention relates to the technical field of motor casings, in particular to a multi-layer sealed motor casing. Background technique [0002] Motor refers to an electromagnetic device that converts or transmits electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque. As a power source for electrical appliances or various machinery, it is widely used in our lives. A motor is usually composed of a casing, a rotor, and the like. In order to allow the motor to dissipate heat better, motor casings with water-cooling structures have appeared in the market at present, but this kind of casing has only one sealing ring. When the sealing ring is broken, cooling water will enter the chamber and damage the motor components. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-layer sealed motor casing, protected by multi-layer sealing ri...
