Introduction to L28/32 diesel engine accessories Function knowledge of bearing sleeve

Shaft sleeve refers to the sleeve on propeller shaft or stern shaft. Bearing is a component that can fix and reduce the friction coefficient of load in the process of mechanical transmission. The similarity between shaft sleeve and bearing is that they both bear the load of shaft.

The bearing sleeve is mainly used in machinery, printing and dyeing, paper making, chemical industry, aerospace, coal, petroleum, automobile, engineering machinery, metallurgy and other industries. It belongs to the general category of sliding bearings. It is a bearing that works under sliding friction. The relative shaft rotates. Generally, it needs to be assisted by the lubrication system.

Marine diesel engine accessories, but the difference between the two is that the shaft sleeve is an integral structure, and when rotating, it is the relative movement between the shaft and the shaft sleeve; The bearing is a split type, and when it rotates, the inner and outer rings of the bearing move relative to each other. But in essence, the shaft sleeve is actually a kind of sliding bearing. The bearing bush is equivalent to the outer ring of the sliding bearing. The bearing bush is integral and moving relative to the shaft, while some of the bearing bushes are fragmented and the relative shaft rotates.
