What are the structural and functional differences between thrust bearings and radial bearings and conventional ball bearings and plain bearings?
Thrust bearings are called thrust bearings, which can bear axial load (axial thrust), such as some large vertical motors and machine tools.Radial bearings bear radial loads, and these bearings are the most widely used.The above two are two kinds of bearings according to the force direction.Journal bearings and rolling bearings.Plain bearings: plain bearings, both inside and outside the ring, there is no rolling body, usually made of wear-resistant materials. Often used in low speed, heavy load, but also useful at high speed; filling lubricating oil and grease. If the copper sleeve belongs to this low - grease, oil pump, water pump and some other high speed and large fan speed reaches 7, 8K conversion of lubricating oil, the small gap between the shaft and the sliding bearing oil film, so that the sliding bearing and the shaft will not damage and wear.Others, as lianjuan2008 said.
First of all, there is a classification error in the question you ask. The thrust bearings and radial bearings are separated according to the direction of the bearing force of the shaft. The ball bearings and the sliding bearings are separated according to the bearing structure,
