no. 1 example

[0059] For the first embodiment, please refer to Figure 1 to Figure 4 .

[0060] The heavy-duty motor structure of the first embodiment includes a motor shaft 1 , a motor casing 2 and two front and rear end cover assemblies 3 .

[0061] The end cover assembly 3 includes an end cover member 32 provided with a bearing support portion 321 and an end cover body 322 , the bearing support portion 321 is fixed in the end cover body 322 , and the bearing support portion 321 is embedded with a bearing 31 . The end cap 32 is generally of one-piece construction.

[0062] The front end and the rear end of the end cover member 32 are respectively detachably fixed with a cover plate member 33 , so as to facilitate the installation of the bearing 31 to the bearing support portion 321 . The cover plate 33 is fixedly provided with a bearing limiting protrusion 331 , and the bearing limiting protrusion 331 is in contact with the outer ring of the bearing 31 to realize the axial positioning of...

Abstract

The invention relates to the technical field of heavy-duty motors, in particular to a structure of heavy-duty motors; it includes a motor shaft, a motor casing and two end cover assemblies; the end cover assembly includes an end cover member provided with a bearing support part and an end cover main body, and the bearing The support part is fixed in the main body of the end cover, and the bearing support part is embedded with a bearing; the two main bodies of the end cover are respectively fixed at the front end and the rear end of the motor casing; the motor shaft includes a heavy load section, a front supported section, The middle section and the rear supported section; the heavy load section is exposed from the front end of the motor casing; it also includes a force balance component; the force balance component includes a resisting member and a force direction changing member with a direction changing protrusion at the bottom end; The first abutting member and the first front bearing are located on the front side of the direction-changing protrusion, and the second abutting member and the second front bearing are located on the rear side of the direction-changing protrusion. The invention can make the bearing bear reasonable force according to the load it receives, and can improve the service life of the motor shaft and the rear bearing.

Description

technical field [0001] The present invention relates to the technical field of heavy-duty motors, in particular to the structure of heavy-duty motors. Background technique [0002] A motor is a device that converts electrical energy into mechanical energy. It uses the energized coil (that is, the stator winding) to generate a rotating magnetic field and acts on the rotor (such as a squirrel-cage closed aluminum frame) to form a magneto-electric rotational torque, and outputs the rotational power through the motor shaft. [0003] With the development of social economy, the load of the motor also has a tendency to increase. This places a heavy load on the motor. However, there is still room for further improvement in the heavy-duty performance of the current motor. SUMMARY OF THE INVENTION [0004] An object of the present invention is to solve or alleviate the above technical problems. [0005] The method adopted in the present invention is a heavy-duty motor structure,...
