Description

A water-cooled front cover

technical field

The utility model relates to the technical field of motors, in particular to a water-cooled front end cover.

Background technique

The motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The motor includes a stator, a stator winding, a frame, a rotor, an end cover, a bearing, and a bearing end cover. Its main function is to generate driving torque. Electrical appliances or various mechanical power sources.

Under normal circumstances, the motor uses air convection to dissipate heat. For the further heat dissipation of the bearing, it is realized through the heat dissipation ribs on the end cover. However, this kind of bearing cooling method wastes materials, and the utilization rate of heat dissipation materials is low, and the effect is poor.

Contents of the invention

The purpose of the utility model is to provide a water-cooled front end cover for the deficiencies of the prior art. The utility model solves the problem of poor cooling effect of the existing motor bearing and waste of cooling materials.

In order to achieve the above purpose, a water-cooled front end cover of the present invention includes a cover body, a cavity is arranged inside the front end cover, and a water pipe is arranged in the cavity, and the cavity is arranged around the outer surface of the bearing.

Preferably, the side of the cover is provided with a water inlet and a water outlet.

Preferably, the water inlet and the water outlet are located on the same side.

Preferably, the shape of the cavity is circular.

Preferably, the cover is provided with reinforcing ribs.

Beneficial effects of the utility model: the front end cover of the utility model is provided with a cavity inside, and a water pipe is arranged in the cavity, and the cavity is arranged around the outer surface of the bearing, and the water flows in the water tube, because the cavity is along the outer surface of the bearing Surrounding setting, so the water pipe surrounds the outer surface of the bearing, the water flow absorbs the heat from the nearby bearing surface, and then flows away, so as to reduce the temperature of the bearing, without wasting heat dissipation materials, and the heat dissipation effect is better, reducing the bearing temperature by about 10 degrees.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figures 1 to 3, the water-cooled front end cover of the present invention includes a cover body 1 and a bearing 2 connected to the cover body 1. A cavity 3 is arranged inside the front end cover, and a water pipe 4 is arranged in the cavity 3. , the cavity 3 is arranged around the outer surface of the bearing 2 .

In this embodiment, water flows in the water pipe 4, because the cavity 3 is arranged around the outer surface of the bearing 2, so the water pipe 4 surrounds the outer surface of the bearing 2, and the water flow absorbs the heat of the nearby bearing surface, and then flows away, thus reducing the bearing capacity. temperature, there is no need to waste heat dissipation materials, and the heat dissipation effect is better, which reduces the bearing temperature by about 10 degrees.

In this embodiment, the side of the cover 1 is provided with a water inlet 11 and a water outlet 12, and the water inlet 11 and the water outlet 12 are connected with the water pipe 4, so that the water flows in the water pipe, and a water circulation device can also be connected externally to save water resources.

In this embodiment, the water inlet 11 and the water outlet 12 are located on the same side of the cover 1 .

In this embodiment, the cavity 3 is annular, and the cavity 3 is arranged around the outer surface of the bearing 2 .

In this embodiment, the cover body 1 is provided with reinforcing ribs 13 to increase the stability of the cover body 1 .

The above content is only a preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation and scope of application. The content of this specification should not be understood as Limitations on the Invention.
