Bearing cooling structure

Abstract

The invention belongs to the technical field of bearing cooling design, and particularly relates to a bearing cooling structure. The bearing cooling structure comprises a shaft neck, a bearing and a bearing cooling oil spray nozzle, an annular shaft neck oil collecting groove is formed in the inner wall of the shaft neck, a plurality of shaft neck oil throwing holes distributed in the circumferential direction are formed in the outer wall of the shaft neck, and each shaft neck oil slinging hole communicates with the annular shaft neck oil collecting grooves; the outer ring of the bearing is connected to the shaft neck in a sleeving mode, a plurality of bearing oil inlet holes are formed in the outer ring, each bearing oil inlet hole correspondingly communicates with one shaft neck oil throwing hole; and the bearing cooling oil spray nozzle is arranged in the shaft neck so as to spray lubricating oil into the annular shaft neck oil collecting groove.

Description

technical field [0001] The application belongs to the technical field of bearing cooling design, and in particular relates to a bearing cooling structure. Background technique [0002] The bearing is arranged on the shaft diameter. During the working process, the parts rotate at a high speed, and the temperature rises sharply. In order to protect the bearing from being damaged, it needs to be cooled when it is working. [0003] At present, the temperature of the bearing is mostly reduced by installing oil nozzles at both ends of the bearing to spray lubricating oil. This technical solution has the following defects: [0004] 1) In some cases, there are protruding structures at both ends of the bearing, and it is difficult to install oil nozzles at both ends; [0005] 2) The lubricating oil sprayed to the bearing is difficult to recover, easy to leak and cause pollution; [0006] 3) The lubricating oil sprayed to the bearing is easy to splash, and it is difficult to directl...

AI Technical Summary

Problems solved by technology

[0004] 1) In some cases, there are protruding structures at both ends of the bearing, and it is difficult to install oil nozzles at both ends;

[0005] 2) The lubricating oil sprayed to the bearing is difficult to recover, easy to leak and cause pollution;

[0006] 3) The lubricating oil sprayed to the bearing is easy to splash, and it is difficult to directly spray it between the inner ring and the outer ring of the bearing, the cooling efficiency is low, and the waste is serious;

[0007] 4) In order to ensure the cooling quality of the bearing, there are usually multiple oil injectors at both ends of the bearing, which are distributed along the circumferential direction. Correspondingly, multiple oil supply pipelines need to be arranged to supply oil to each oil injector, resulting in a complex structure. Difficult to arrange
