Sliding bearing is usually said that the plane of the bearing, its form is simple, the contact area is large, if good lubrication, anti-wear performance will be very good, will be a long bearing life.Sliding bearing of the bearing capacity is big, high rotary precision, lubricating film have impact resistant effect.So get extensive application in engineering.But he can't maintain enough lubricating oil is the chief drawback of reserves, once the lack of lubricant, it immediately have serious wear and lead to failure.
Sliding bearing is a lot of more phyletic:
(1) can be divided by can withstand the load in the direction of the radial (centripetal) sliding bearing and thrust (axial) sliding bearing.
(2) according to the types of lubricant grease can be divided into oil lubricated bearing, bearing, water lubricated bearing, gas bearings, solid lubrication bearings, magnetic bearings and magnetic bearing seven classes.
(3) according to the lubrication film thickness can be divided into thin film lubrication bearing and thick film lubrication bearing two categories.
(4) according to the bearing shell material can be divided into bronze bearings, bearings, plastic bearings, cast iron jewel bearing, powder metallurgy bearings, self-lubricating bearing, oil bearing, etc.
5. According to the bearing shell structure can be divided into round, elliptical bearing, bearing the three oil bearing, stepped surface bearing, tilting tile bearing and foil bearing, etc.
Oil free or less oil lubrication, in particular, apply to cannot go or it's hard to go places, but when use less maintenance and maintenance.Wear-resisting performance is good, small friction coefficient, long service life.Has the right amount of elastic-plastic, can the stress distribution in wide contact surface, improve the bearing capacity.The static friction coefficient, can eliminate the crawling under low speed, so as to ensure the accuracy of the mechanical work.Can reduce the mechanical vibration, reduce noise, prevent pollution, improve working conditions.
