Bearing industry portal net news: 1. The topic content This standard specifies the classification method of joint bearing, and the commonly used joint bearing structure. 2. The reference standard GB 3944 joint bearing vocabulary 3. The classified method of joint bearing 3.1 joint bearing can bear load according to its direction or nominal contact Angle different, divided into the following kinds of. 3.1.1 centripetal knuckle bearing - used to bear radial load, its nominal contact Angle from 0 degrees to 45 degrees, according to its nominal contact Angle is different, can divide again: A. the radial contact to the heart joint bearing - nominal contact Angle of 0 degree to the heart joint bearing, suitable for bear radial load. But also can bear radial load at the same time, the little bear axial load. B. angular contact centripetal knuckle bearing - nominal contact Angle is greater than 0 degrees, but less than or equal to 45 degrees to the heart joint bearings, can bear radial load and axial load and the role of joint load. 3.1.2 thrust bearing joints - used to bear axial load, the nominal contact Angle is greater than 45 degrees to 90 degrees, according to its nominal contact Angle is different, can divide again: A. the axial thrust bearing joints - nominal contact Angle of 90 degrees of thrust bearing joints, suitable for pure under axial load. B. angular contact thrust bearing joints - nominal contact Angle is greater than 45 degrees, but less than 90 degrees of thrust bearing joints, suitable for bear axial load, but also can withstand the combined load (when the radial load value shall not be greater than 0.5 times that of the axial load). 3.2 joint bearing according to its outer ring structure is divided into: A. the overall bearing outer ring joint; B. double half bearing outer ring joint; C. single slit bearing outer ring joint; D. double slit outer ring (cutting points circle) joint bearing. 3.3 joints, rod end bearing according to whether attached or installed on the rod end can be divided into: A. general joint bearing; B. rod end joint bearing. 3.4 joint bearing should be added according to the work whether lubricant can be divided into: A. the self-lubricating joint bearing; B. self-lubrication of joint bearing. 3.5 joint bearing can bear load according to its direction, nominal contact Angle and structure is divided into: A. the centripetal knuckle bearing; B. angular contact bearing joints; C. thrust bearing joints; D. rod end joint bearing.
