Double-fulcrum sliding bearing

Abstract

The invention discloses a double-fulcrum sliding bearing, and relates to the field of sliding bearings. The bearing comprises a bearing inner ring. A bearing outer ring is arranged on the outer portion of the bearing inner ring in a sleeving manner. The bearing outer ring and the bearing inner ring are fixed through pins. Multiple bearing bush blocks are fixed to the inner layer of the bearing inner ring. The multiple bearing bush blocks are combined and arranged in a circular, uniform-distribution and surrounding manner. Each bearing bush block is connected with the bearing inner ring and thebearing outer ring through two mechanical supports. The mechanical supports are adopted for the bearing and used as oil spraying devices, and therefore materials are saved, the bearing capacity can be improved, and loss and oil consumption of the positions of fulcrums are reduced.

Description

technical field [0001] The invention relates to the field of sliding bearings, in particular to a double fulcrum sliding bearing. Background technique [0002] Compared with other sliding bearings, the tilting pad sliding bearing with a single mechanical support has higher stability and is suitable for high-speed and light-load occasions; but with the increasing requirements of modern production, the requirements for all aspects of sliding bearings Performance also put forward higher requirements. Against this background, the disadvantages of plain bearings with a single mechanical support also emerge. The high cost brought by its complex structure, insufficient load capacity, friction loss at the fulcrum and large demand for oil supply make the variable fulcrum sliding bearing more and more unable to meet the requirements of industrial production. [0003] Moreover, the current oil supply technology makes the lubricating oil directly enter the pad through the bearing body...

Problems solved by technology

The high cost brought by its complex structure, insufficient carrying capacity, friction loss at the fulcrum and large demand for oil supply make the variable fulcrum sliding bearing more and more unable to meet the requirements of industrial production

[0003] Moreover, the current oil supply technology makes the lubricating oil directly enter the pad through the bearing body, which often leads to insufficient oil supply of the lubricating oil, thereby increasing the loss of the bearing and shortening the service life of the bearing
