Analysis on the application of hammer crusher rotor and main shaft

Due to the different working environment of the hammer crusher, some problems should be paid more attention to in the application of the hammer crusher. The following is an analysis of what problems should be paid attention to for the rotor and main shaft of the hammer crusher:

First, the straightening force applied should not be too strong to prevent the spindle from cracking at the hidden danger of cracks;

Second, when the amount of bending is large, straightening should be carried out several times;

Third, the correction value should appropriately exceed the bending value of the shaft to eliminate the influence of the springback deformation of the shaft after the straightening force is removed;

Fourth, when straightening, after applying the straightening force, stay for a while, and at the same time use a small plumb hammer to gently tap the shaft surface along the shaft surface to eliminate internal stress and prevent straightening Deform again

Fifth, in the straightening process, the bending value of the shaft should be continuously measured until it meets the standard. That is, when the shaft is Φ200-300, the bending value should not exceed 0.06mm, and the bending value of the straightened shaft should not exceed 0.1-0.15mm.

The main shaft is the main stress part of the crusher. The traditional method is used to check and optimize the design, the process is complicated and cumbersome. The technicians provide a reliable basis for redesign and modification through tracking services for the crushing and crushing of various materials of the products shipped out of the factory. According to the analysis results, its performance was evaluated, and based on this, a reasonable structure size was obtained. After optimization, the quality of the main shaft of the hammer crusher was reduced, while its strength and rigidity were ensured.
