Different working environment of the hammer crusher, hammer crusher should be more attention to some of the problems, hammer crusher rotor and spindle should pay attention to what you Analysis below:

First, the straightening force applied is not excessive, to prevent the spindle of collapse at the crack hidden;

Second, when the bending amount is larger, should be several times for straightening;cylindrical roller bearings

Third, the correction value should appropriately than bending axis to eliminate the shaft to remove the the straightening force after springback deformation impact;

Fourth, straightening and straightening force to stay for some time, while in the surface of the shaft with a small lead hammer gently tap along the axial plane, in order to eliminate the internal stress and prevent distortion straightening and then ;

Fifth, in the straightening process, the bending of the axis to constantly measure, until the standards. Φ200-300 that axis bending value should not exceed 0.06mm, after straightening shaft bending value shall not exceed 0.1 to 0.15 mm.angular contact bearings

Spindle as the main force of the crusher parts, using traditional methods to check the optimal design, the process is complicated. Technical staff through the the broken broken factory products on a variety of different materials tracking service, to provide a reliable basis for re-design and modify. To evaluate its performance for the analysis of results, and this basis, reasonable structure size, optimized to reduce the quality of hammer crusher spindle, while maintaining its strength and stiffness.angular contact ball bearings
