Repair Of Rotor Spindle Of Portable Coal Crushing Machine

Many people are familiar with Portable Coal Crushing Machines. With the wide application of Portable Coal Crushing Machines, more and more research has been done on their components. The rotor part of the Portable Coal Crushing Machine consists of the main shaft, disc, pin shaft and rotor. The rotor runs at high speed in the crushing chamber driven by the motor. However, in actual production work, the spindle of the rotor part of Portable Coal Crushing Machine is easily damaged due to various factors. At this time, it needs to be repaired and corrected in time. The following points need to be paid attention to when repairing.

Correction Force And Times

When correcting the spindle of Portable Coal Crushing Machine, do not use excessive correcting force, and do not make excessive corrections to prevent the spindle from cracking due to hidden danger. When the bending is large, the correction should be carried out several times.


When correcting the spindle of a Portable Coal Crushing Machine, the correcting value should exceed the bending value of the spindle appropriately, so as to better eliminate the influence of the springback deformation of the spindle after the straightening force is removed, otherwise the correcting effect will not be achieved.

Correction Time

Correction force should be added to stay for a period of time. At this time, small lead hammer should be used to lightly tap along the axis surface to better eliminate the internal stress, so as to prevent the re-occurrence of deformation after correction.

Measurement of Bending Value

After correction, the bending value should meet the standard. In the process of correction, the bending value of the axis should be continuously measured until it meets the standard.
