The characteristics of the structure, government's single row taper roller bearings and use

Government's single row tapered roller bearing inner and outer circle can be installed respectively, in the process of installation and use can be adjusted by the axial and radial clearance and preloaded mounting can be also. Single set of single row circular cone roller bearings can limit axis in one direction or the shell axial displacement, carry axial load in one direction, generally in the shaft installation is at each end of a single row circular cone roller bearings, bearing inner and outer side relative to the installation of the same name, which is opposite the two sets of bearings on the shaft or installed back to back. Type 30000 single row tapered roller bearing contact Angle in 10 & deg; ~ 18度; Between, used to bear joint mainly consisting of radial load and axial load, the type 31300 single row tapered roller bearing contact Angle in 27 & deg; ~ 30度; Between, is used to carry axial load of radial and axial load. These bearings are strictly, to install the concentricity of internal and external ring after installation Angle deviation is not allowed to exceed 2 & prime; ; After installation at the same time the size of the bearing axial clearance, had a great influence on bearing can good work, axial clearance after hours, the temperature is high, the axial clearance is too large, the bearing is easy to damage during the installation and operation, it is important to pay special attention to the adjustment bearing axial clearance, in general, inner ring color guard and big end roller sets in wear shows that axial clearance is too small, small inner ring guard and rolling body side shows abnormal impellers, wear and so on axial clearance is too large, according to the running status of bearings for proper adjustment.
