The structure of the sliding bearing
Generally speaking, bearing and bearing seat sliding bearing.Sliding bearing according to the direction of the load, it can be divided into radial sliding bushing (mainly bear radial load) and the thrust bearing (mainly bear axial load).The structure of common radial sliding bearing are integral and Split two kinds.
1. The integral sliding bearing
sliding bearing Image is a common and radial sliding bearing, bolt connected to the frame.Bearing hole into made of anti-friction material bearing shell (or called collar), on top of the bearing seat is equipped with oil cup, oil hole shaft sleeve, the inner surface open axial oil groove to assign lubricating oilSlippery.Integral sliding bearing the biggest advantage is simple structure, but bearing excessive wear on the surface can't adjust bearing clearance;Journal only from end loading, the heavy axis or has the intermediate shaft neck shaft installation inconvenience, even can't install.In order to overcome these two shortcomings, recoverableUsing split sliding bearing.

2. Split sliding bearing
Split sliding bearing as shown in slide bearing image, consists of bearing seat, bearing cover, subdivision bearing shell (divided into upper and lower tile) and the connecting bolts, etc.With load bearing subdivision surface should be close to the vertical direction, most bearing subdivision surface is horizontal, and diagonal.Bearing cover and the bearing seat .Subdivision surface is often done step, in order to locate and prevent rupture at work.Its bearing wear of bearing clearance can be used to reduce subdivision surface of metallic gasket or scraping match method to adjust the bearing metal.

Convenient operation split sliding bearing, bearing and axial clearance can be adjusted, is widely used.
