Common bearings are spherical roller bearings, single row, double row tapered roller bearings, double row cylindrical roller bearings, four-point contact ball bearings, ball bearings and so on;
Bearing specifications for the initial selection is to determine the diameter of the shaft bearing size, the input shaft speed, should be selected with the inner diameter of the load capacity of the larger specifications, the intermediate shaft has two pairs of gears meshing force on the bearing, in line with the larger, should also be selected with the inner diameter of the load capacity of the larger specifications;
Output shaft speed is low and only a pair of gear meshing force acting on the shaft and bearings, you can choose the same inner diameter of the load capacity of medium or smaller bearings, but the output shaft and machine spindle rigid connection and impact, it should be selected load can be larger bearings.
