In the shafting, the role of bearings is known, the general bearings should have shaft sleeve, as if outside the shaft lining of bread Expert answer please!
The Bush is attached to the fixed bearing and the shaft sleeve is wrapped on the shaft
The 2 floor is very correct and very detailed! The bushing will appear only in the rudder system! Shafts have only bushings or covers
Bearing is an important component of modern machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement and guarantee its rotation accuracy. According to the friction property of the moving element, the bearings can be divided into two kinds: rolling bearing and sliding bearing. Among them, the rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial dimensions, vibration and noise are relatively large, and the price is higher.Bushing liner ring in the valve application area, the Bush in the valve cover, generally use PTFE or graphite and other corrosion-resistant materials, used for sealing.The sleeve is a cylindrical mechanical part that is attached to the shaft. It is a part of the sliding bearing. Generally speaking, the axle sleeve and the bearing seat adopt the interference fit, and the shaft and the gap fit.
