Mine Scraper Winch Common Reducer Fault Analysis And Solution


In the long-term operation of mine scraper winch reducer, wear, leakage and other faults often occur.


Common failures of mine scraper winch:


1. Wear of reducer bearing chamber, including wear of shell bearing box, box bore bearing chamber and gearbox bearing chamber


2, reduction gear shaft diameter wear, the main wear parts in the shaft head, keyway, etc


3. The bearing position of the transmission shaft of the reducer is worn


4. Leakage of reducer joint surface.


For the problem of wear, the traditional solution of enterprises is repair welding or after brush plating machine processing repair, but both have certain disadvantages: repair welding high temperature thermal stress can not be completely eliminated, easy to cause material damage, resulting in bending or fracture parts; And brush plating by the thickness of the coating, easy to flake, and the above two methods are used to repair the metal, unable to change the "hard to hard" relationship, in the combined effect of the forces, will still cause a second wear. For some large bearing enterprises can not be solved on site, more rely on external repair. Application of high polymer material to repair, can neither from removed from machining repair welding thermal stress effect, repair the thickness is not restricted, and the product of metal materials do not have rolled back, can absorb the impact of vibration equipment, avoid wear and tear, and greatly prolong the service life of equipment components, save a lot of downtime for the enterprise, creating huge economic value. But for the leakage problem, the traditional method needs to remove and open the reducer of the mine scraper winch, replace the sealing gasket or apply sealant, not only time-consuming and labourer, and it is difficult to ensure the sealing effect, but also will appear again in the operation of leakage.
