Problems solved by technology

[0005]In addition to traditional lubrication methods, super lubricating materials have also been born in the prior art, which can be applied to sliding bearings, which can greatly improve the performance of sliding bearings. Therefore, it is possible to replace rolling bearings with sliding bearings, but the existing super-lubricating materials are still difficult to apply to such a large area of ​​bearing contact surface

Abstract

A grease lubrication two-way thrust conical sliding bearing comprises a bearing inner ring and a bearing outer ring which are assembled in a matched mode. The bearing outer ring and the bearing inner ring are in friction contact to form two friction conical surfaces with different inclination directions, and solid super-lubrication coatings are arranged on the friction conical surfaces. A grease storage cavity which extends in the circumferential direction and is used for storing lubricating grease is formed in the bearing outer ring or the bearing inner ring, and two sets of grease storage cavity grease supply holes are formed between the grease storage cavity and the two friction conical surfaces respectively to supply lubricating grease to the two friction conical surfaces respectively. An outer ring lubricating grease guide groove is formed in the inner wall of the bearing outer ring, and an inner ring lubricating grease guide groove is formed in the outer wall of the bearing inner ring. According to the bearing, a grease lubrication technology and a solid super-lubrication coating technology are combined to approach a theoretical super-lubrication state, the performance of the bearing is greatly improved, the service life of the bearing is greatly prolonged, and it is made possible to replace a rolling bearing with the sliding bearing.

Description

Technical field [0001] The present invention relates to the field of sliding bearing, in particular to a grease lubricating bidirectional thrust cone sliding bearing. Background technique [0002] Bearings are important basic components of mechanical equipment, wherever mechanical equipment is inseparable from bearings. Its basic function is that the support mechanism is rotated, reducing the friction coefficient in its motion, ensuring its rotation accuracy. In human labor production activities, in order to reduce friction, improve the efficiency, the sliding bearing and rolling bearings are invented. Human initially invented the sliding bearings. With the advancement of technology, it was found that the friction coefficient of the rolling bearing is much lower than the sliding bearing, invented and using various types of rolling bearings. However, these two bearings are compared, and in addition to the rolling bearing ratio of the friction coefficient of the rolling bearing, ot...
