Basic knowledge of the bearing

1. 1: rolling bearing load and the relative motion of the parts to each other in supporting intercropping of rolling bearing, it includes race parts and with or without isolation or guide roller group. Can be used to bear radial, axial or by a combination of radial and axial load. 1. 2 angular contact bearings, ball and ring nominal contact Angle is greater than 0 °, and less than 90 ° of rolling bearing. 1. 3 outer spherical bearing, outside spherical and with lock a wide centripetal roller bearing inner ring. Mainly for the use of simple shell. 1. Four linear motion bearings: two raceway in rolling direction on the relative linear movement of the rolling bearing. 1. 5 ball bearing: roller rolling bearing is the ball. 1. Deep groove ball bearing: each ring has one of the cross section is about the ball Zhou Changsan points of continuous groove type of raceway centripetal ball bearings. 1. 7 thrust ball bearings, roller is ball thrust ball bearing. 1. 8 roller bearings, roller roller of the rolling bearing. 1. Nine cylindrical roller bearings, roller is the centripetal roller bearing cylindrical roller. 1. 10: tapered roller bearing is tapered roller roller of centripetal roller bearing. 1. 11 needle roller bearing, rolling body is needle to the heart of rolling bearing. 1. 12: spherical roller bearing is a convex spherical surface or concave roller roller the heart to the heart of rolling bearings. Has a convex spherical roller bearing, a spherical outer ring raceway form; Has a concave roller bearing, which has a spherical raceway. 1. 13 thrust roller bearings, roller is roller thrust bearing. 1. 14 thrust cylindrical roller bearing, rolling body is cylindrical roller thrust bearing. 1. 15 thrust tapered roller bearings, roller is tapered roller thrust bearing. 1. Thrust needle roller bearing: is needle roller thrust bearing. 1. 17 spherical roller thrust bearing, rolling body is a convex spherical surface or concave roller thrust self-aligning roller bearing. A convex spherical roller bearing race of raceway is spherical shape, has a concave spherical roller bearing shaft ring raceway is spherical shape. 1. 18 arrange ushering bearing: the centripetal bearing with a combination of a component, with the bearing axis parallel to the surface of the support a mounting screw on the floor. 1. 19 joint bearing: sliding contact for spherical surface, mainly is suitable for the swing motion, motion and rotation motion of the tilt spherical sliding bearing. 1. 20 combination bearing: a set of bearings at the same time by the above two or more bearing structure of rolling bearing. Such as needle roller and cylindrical roller bearings, thrust needle roller and thrust ball bearings, needle roller and angular contact ball bearings, etc. 1. 21 other bearing: in addition to the above other than the structure of the rolling bearing.
