How are the classifications of joint bearings classified?
The structure of the joint bearing is simpler than that of the rolling bearing. It is mainly composed of an inner ring with an outer sphere and an outer ring with an inner spherical surface. Joint bearing generally used for swinging movement of the lower velocity (i.e., angular) because the sliding surface is spherical shape, can also be used as a tilt movement in a certain range of angles (i.e. aligning movement), the support shaft and the shaft casing hole concentricity is larger, can still work normally.Main category: joint bearing thrust bearing, angular contact bearing, thrust bearings, rod end bearings, self-lubricating spherical joint bearing, self-lubricating angular contact bearing, self-lubricating thrust joint bearing, self-lubricating joint rod end bearings.
Classification of joint bearings, GB/T, 304.1-2002First, according to its load direction or nominal contact angle, divided into:Radial joint bearings, angular contact joint bearings, thrust joint bearings.Two, according to the structure of its outer ring, divided into:Integral outer ring, single slit outer ring, double slit outer ring and double half outer ring. The integral outer ring comprises an integrally extruded outer ring and an outer ring with an assembly groove.Three, according to whether it is attached to the end of the rod and installed on the end of the rod, divided into:General joint bearings and rod end joint bearings.Four, according to their work whether to add lubricant, divided into:Lubrication type joint bearing, self lubrication type joint bearing (or maintenance free joint bearing), boundary lubrication joint bearing.Five, according to the load direction, nominal contact angle and structural type, it can be generally divided into:Radial joint bearings, angular contact joint bearings, thrust joint bearings, rod end joint bearings.The above standards are extracted according to the national standards. Some of them have been added and supplemented according to years of experience and experience. Deficiency, please correct and exchange.
The classification of joint bearings: radial joint bearings, angular contact joint bearings, thrust joint bearings, rod end joint bearings.First, according to different classification methods, according to different load directions or nominal contact angles, the joint bearings can be divided into the following types.1, radial joint bearings - used to bear radial load, its nominal contact angle from 0 degrees to 45 degrees, according to its nominal contact angle of different, can be divided into:A. radial contact radial joint bearings - nominal contact angle of 0 degrees of radial joint bearings, suitable for bearing radial load. But it also can bear the radial load and bear little axial load.B. angular contact radial joint bearings - nominal contact angle greater than 0 degrees, but less than or equal to 45 degrees of radial joint bearings, can bear radial load and axial load simultaneous action of the combined load.
