Transfer requirements and contact angles of radial joint bearings
Aug 31, 2018

The radial joint bearing can be divided into a radial joint bearing and a thrust joint bearing in use according to the direction in which the load can be applied or the nominal contact angle.

1. Radial spherical plain bearings - used to withstand radial loads, the nominal contact angle from 0 degrees to 45 degrees, according to their nominal contact angle, can be divided into:

a. Radial contact radial spherical plain bearing - a radial spherical plain bearing with a nominal contact angle of 0 degrees, suitable for bearing radial loads. However, it can withstand radial loads while withstanding a small axial load.

b. Angular contact radial joint bearing—A radial joint bearing with a nominal contact angle greater than 0 degrees but less than or equal to 45 degrees can withstand the combined load of radial load and axial load.

The radial joint bearing should follow the force applied by assembly and disassembly under any circumstances. It can be directly transmitted through the spherical sliding surface to a certain extent. In addition, auxiliary loading and unloading tools such as sleeves and detachers should be used. The loading and unloading force applied by the outside is directly and uniformly applied to the ferrule to be fitted, or the load-free loading and unloading is performed by an auxiliary method such as heating.
