Abstract

The invention discloses a sliding bearing of a spiral floating bushing, comprising a bearing outer ring (1), a shaft neck (2) and a floating bushing (3), wherein the floating bushing (3) is mounted between the shaft neck (2) and the bearing outer ring (1) and provided with a spiral groove (4) which is through along the radial direction. The invention can ensure that the shaft neck, a shaft hole and the floating bushing of the bearing are loaded more uniformly and worn almost at the same time to reduce uneven abrasion, can improve the floating capability of the floating bushing and the lubricating condition of the bearing, improve the load distribution of the bearing and prolong the service life of the bearing.

Description

technical field

[0001] The invention belongs to the technical field of bearings, and in particular relates to a spiral floating sleeve sliding bearing. Background technique

[0002] Sliding bearing is a kind of bearing commonly used in mechanical engineering. It mainly supports the shaft and the parts on the shaft, maintains the rotation accuracy of the shaft or the rotating parts on the shaft, and reduces the friction between the rotating shaft and the supporting or rotating parts on the shaft. and damage. Sliding bearings are suitable for use under conditions such as high speed, high precision, heavy load, high shock and vibration, and limited radial space size.

[0003] Floating sleeve sliding bearing is a kind of sliding bearing. The introduction of the floating sleeve can reduce the relative sliding speed between the sliding friction pairs of the bearing, thereby reducing wear, reducing frictional power loss, and prolonging the service life of the bearing. The floati...

Embodiment Construction

[0023] Such as figure 1 , 2 , 3, 4, and 5: a spiral floating sleeve sliding bearing, including a bearing outer ring 1, a journal 2 and a floating sleeve 3, and the floating sleeve 3 is installed between the journal 2 and the bearing outer ring 1 , A helical groove 4 is opened on the floating sleeve 3, and the helical groove 4 penetrates radially.

[0024] At least two sections of floating sleeves 3 are arranged between the bearing outer ring 1 and the journal 2 , and the floating sleeves 3 are arranged side by side along the axial direction of the journal 2 .

[0025] Such as Figure 5 : Multi-stage floating sleeves are independently arranged side by side along the axial direction of the journal 2, and each section can rotate freely without affecting each other. Each floating sleeve can automatically adjust the floating according to the working conditions through the running-in of the bearing, so that the bearing is worn Uniform synchronization to extend service life.
