Description

Technical Field

[0001] The utility model relates to the technical field of floating bearings, in particular to a floating bearing with a stable load-bearing function. Background Art

[0002] A floating shaft refers to a shaft that can float up and down, which is newly added to the original vehicle. In other words, a suspension with a liftable tag axle is newly added. There are gaps between the full floating bearing and the rotor shaft and housing bearing. When the rotor shaft rotates at high speed, the lubricating oil with a pressure of 0.25-0.4Mpa fills these two gaps, so that the floating bearing rotates in the same direction as the rotor shaft in the inner and outer oil films, but its rotation speed is much lower than that of the rotor shaft, thereby greatly reducing the relative linear speed of the bearing relative to the bearing hole and the rotor shaft.

[0003] After searching, the patent with application number: CN201720845818.2 discloses a high-performance floating bearing. The ball used in the existing floating bearing is a sphere, and the contact area with the inner ring of the bearing is relatively small. The added grease is directly located on the ball and is placed once. After a period of use, it is easy to overflow, resulting in a situation where there is no grease on the surface of the ball, causing the ball to wear. For this reason, a floating bearing with a stable load-bearing function is proposed. Utility Model Content
