Crusher main content and attention matters of the rotor spindle repair, the dangerous area of crusher rotor, main contents of the rotor overhaul
where is the dangerous area of crusher rotor mainly distributed?
according to the analogue simulation stress analysis cloud chart, we can see clearly that the dangerous areas of crusher rotor are mainly distributed in hammer rockk, hammer shaft hole on hammer dish, hammer dish outer edge, hammer shaft and mainshaft bearing shaft shoulder, etc.
what are the main contents of the rotor overhaul are?
the main contents of rotor overhaul are: checking on and bending repair straightening hammers and main shaft of the hammer crusher, lock device checking and repairing, the repair of rotor and outer edge of hammer and hammer dish replacement, repair and replacement and gradation of hammer, cleaning and maintenance of bearing and bearing pedestal and sealing device.
what are the main content and attention matters of the rotor spindle repair are?
due to the larger axial neck, heating difficulty, and heating time is long, and the temperature is not easy to be controlled uniformly, straightening should be paid attention to the five following points:
1、 the pressured straightening force should not be so large, to prevent the spindle from cracking on the hidden trouble flaws.
2、 when bending quantity is larger, straightening should be done by several times.
3、 correcting numerical should be properly over the shaft bending value to eliminate the influence of rebound deformation when the straightening force is removed from the shaft.
4、when in straightening, straightening force should be kept for a period of time. at the same time, using small plumb bob to knock the axial plane gently and these operations can relieve residual stress and prevent deformation occur ing when the straightening force is removed.
5、 in the straightening process, shaft bending value should be measured continually until complying with the standards. when the shaft is φ200-300, the shaft bending value should not be over 0.06mm. for the straightened shaft, bending value should not be over 0.1-0.15 mm.
