1、Types of Bearing轴承的类型Bearings are used to guide and to support shafts and axles. Care must be taken to create as little friction and wear against the bearing as possible.轴承作用：引导运动和支撑物体Depending on the size 尺寸and working direction of the force力的工作方向 which is applied to the bearing it is differentiate
2、d in· Journal bearings径向轴承 take the forces across the bore axle. These are also known as angular角接触轴承 bearing or radial半圆的 bearing.· Axial bearings止推轴承 take the force in the direction of the bore axle. These are also known as thrust bearings推力轴承.There are plain bearings滑动轴承 and rolling bea
3、rings滚动轴承 for all types of stress cases.In their simplest version, the rolling bearings consist of two ball races (outer and inner ring), the rolling elements and bearing cage球笼.The rolling elements roll on the tracks of the ball race. The sliding friction is replaced by the lower rolling friction.
4、The bearing cage keeps the rolling elements in a specified gap from each other. Rolling bearings are almost com-pletely maintenance free.Roller bearings differ in their basic shapes:滚动轴承的不同外形· ball bearing球轴承,· roller bearing滚柱轴承,· tapered roller bearing圆锥轴承,· needle bearing滚针轴承,
