Description

Technical Field

[0001] The utility model relates to the technical field of anti-oil seepage of bearing bushes, and more specifically to an anti-oil seepage structure of a bearing bush of a high-voltage motor. Background Art

[0002] In high-voltage motors, the role of bearings is particularly important because they need to withstand greater loads and pressures. Bearings, also known as bearing bushings, are the parts of the sliding bearing that contact the shaft neck and usually have a smooth semi-cylindrical shape.

[0003] The anti-oil seepage structure of the high-voltage motor bearing is designed to prevent the lubricating oil from being thrown out or leaking due to pressure difference or the force of rotating parts, keep the inside of the motor clean and avoid oil loss. The design and improvement of these structures are to prevent the lubricating oil of the bearing from being thrown out or leaking along the shaft penetration due to various reasons during the operation of the high-voltage motor, ensuring the stable operation of the motor and extending its service life.

[0004] It is very important to ensure the cleanliness of the lubricating oil. When injecting the lubricating oil, foreign matter should be avoided from mixing in, and the oil filter should be cleaned regularly and the filter element and lubricating oil should be replaced to keep the lubricating oil clean. This method can effectively reduce the leakage of the bearing shell. In the existing split or split bearing shell, the filter device is connected to the bearing seat or bearing cover through a double-headed stud. However, when the filter device needs to be cleaned or disassembled, it is necessary to first unscrew the bolts and then take out the filter device, and then clean or replace and repair the filter device, and finally install the filter device back in place, and then fix the filter device by tightening the bolts. This method is troublesome, laborious and time-consuming, and it will also reduce the efficiency of replacing or cleaning the filter device.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a high-voltage motor bearing oil leakage prevention structure. Utility Model Content
