Reducer bearing maintenance to this site operation

Because of the speed reducer running conditions, long-term operation, often wear and leakage problems, mainly has the following kinds: 1, reducer bearing wear, bearing box, including shell, the casing hole wear of bearing housing, gearbox bearing chamber; 2, gear reducer shaft diameter of axle wear, the worn parts in main shaft head, slotting, etc; 3, reducer shaft bearing wear; 4, reducer parting surface leakage and oil leakage in areas such as the fastening bolts. Above equipment problem, once the attack cannot be handled quickly and efficiently in the first place, will seriously affect the consumption of the enterprise. For reducer bearing wear problem, traditional processing method is to brush plating or after repair welding machine repair, but both have some disadvantages, and the thermal stress generated by the repair welding with high temperature cannot complete alleviation, cause material damage, cause components present bend or break; Brush plating coating thickness restrictions, easy to peel, and above two ways are using metal repair metal, not change 'hard in hard' cooperate relationship, under all kinds of force in collaboration with, still can form to wear again. For some large reducer processing is not the spot, much depends on outsourcing repair. At present this kind of problem has been improved greatly, due to the large local enterprises start to use sauvy carbon nano polymer materials to stop to repair. Sauvy carbon nano polymer material which has strong adhesion, excellent comprehensive properties such as compressive strength, can live from removed from machine repair, also can remove the machining repair, no repair welding thermal stress effect, repair the thickness is not restricted, and the product of metal materials do not have the concession, can absorb the impact of vibration equipment, to prevent wear may again, and greatly prolong the life of the use of equipment parts, frugal lots of down time for the enterprise, invention of great economic value. Sauvy SD7101H on-site repair reducer bearing a wear case show: reducer: high-speed shaft bearing wear, journal, wear width 120 mm, 220 mm, 23144 cc/c4w33 bearing type, bearing and shaft burning stick form bearing damage. Plan: repair parts coated sauvy SD7101H carbon nano polymer material after curing, application of machining restore restore has the diameter of axle and the size of interference, effectively prevent the traditional repair welding method to form thermal stress damage.
