the protective sealing structure is arranged on the connecting part of the rotating shaft and the bearing and is fixedly connected with the end cover.

In the above scheme, the motor main body includes a structure body which is composed of a drive circuit and components of the existing motor and can realize the basic functions of the motor, and is used for driving the rotation of the rotating shaft; the end cover is used for fixing the bearing and protecting the sealing structure; the operation and maintenance personnel can connect and assemble the interior of the motor after opening the end cover.

Wherein, the dustproof cover is provided with a connecting hole; the dustproof cover is connected with the end cover through the connecting hole.

The motor also comprises a shaft sleeve, and the shaft sleeve is arranged around the rotating shaft; the inner side of the copper sleeve is of a circular arc structure.

In the scheme, in the rotating process of the motor, the arc-shaped structure of the copper sleeve effectively reduces the contact area with the shaft sleeve, so that the motor can be conveniently worn in a preset state in the shortest time, and the overall performance of the motor is improved; the setting of axle sleeve has further improved the sealed performance of leak protection oil of motor.

Compared with the prior art, the utility model discloses technical scheme's beneficial effect is:

Detailed Description

The drawings are for illustrative purposes only and are not to be construed as limiting the patent;

for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product;

it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.

Example 1

As shown in fig. 1, a motor with a protective sealing structure comprises a motor, wherein the motor is provided with the protective sealing structure 1, and the protective sealing structure 1 comprises a dust cover 11 and a copper sleeve 12; the dust cover 11 is fixedly connected with the copper sleeve 12.
