There are many types of crusher bearings, bearing the bearing is mainly based on the situation and the requirements of self-aligning to the choice of the rotor speed between 900 to 1100 hammer crusher, for example, because of its high bearing speed, Load, and work a long time, and the most important thing is, after a long time after the work, because of the uneven wear of the head of the unbalanced additional force, when the hammer uneven wear serious , This force will become the main part of the total load. The distance between the bearings, the shaft will produce deflection, in addition, the center of the bearing is difficult to ensure concentric.
Crusher bearing the actual work, the temperature difference before and after work is very large, in order to adapt to the expansion of the shaft and the impact of different shells to prevent the bearing stuck. We can be fixed at one end of the bearing, one end can be moved, so that the bearing in the circumference of the relative position of the inner and outer rings will not be much change, can still work, can also make the outer edge of the hole with the more easily, To ensure that the cylindrical relative to the hole can do axial movement.
In order to facilitate the installation and removal of the bearing on the spindle, must take into account the bearing of the cut-off surface, so you can not consider along the axial installation and dismantling of the bearing components, can be preferred to completely separable bearings.
On the rolling bearing to withstand the axial force and radial force are relatively large, and the shaft is slender shaft, produce bending moment, the vibration will be relatively large, you can use lubricating oil lubrication.
