Description

Wear-resisting shaft sleeve with self-lubricating function

Technical Field

The invention relates to the technical field of shaft sleeves, in particular to a wear-resistant shaft sleeve with a self-lubricating function.

Background

The shaft sleeve is a cylindrical mechanical part sleeved on the rotating shaft and is a component of the sliding bearing. Typically, the sleeve is an interference fit with the bearing seat and a clearance fit with the shaft. The shaft sleeve and the bearing are the same in that both bear the load of the shaft, and the difference between the shaft sleeve and the bearing is that the shaft sleeve is of an integral structure and relatively moves between the shaft and the shaft sleeve when rotating; the bearing is split, and the inner ring and the outer ring of the bearing move relatively when the bearing rotates. But in essence the sleeve is just one kind of sliding bearing.

The axle sleeve mainly sets up in the pivot, the guard action to the pivot, but the pivot also is constantly rubbing in supporting use with the axle sleeve, the friction not only can cause the direct wearing and tearing of axle sleeve, the department of rubbing still can produce higher heat, further aggravate the wearing and tearing of axle sleeve, at present, often guarantee abundant lubrication between the two through the mode of adding lubricating oil between axle sleeve and pivot, service life with extension pivot and axle sleeve, lubricating oil is the consumer, along with the pivot rotates, lubricating oil can consume totally, need add the replenishment, but the axle sleeve among the prior art, need artifical manual adding lubricating oil usually, trouble very, and because the pivot is in the fast revolution, when adding lubricating oil, lubricating oil splashes everywhere easily, not only can cause the waste of lubricating oil, and dirty surrounding environment easily. Therefore, a wear-resistant shaft sleeve with a self-lubricating function is provided.
