How reducer bearing chamber to fix - bearing knowledge

Reducer is generally used in low speed high torque transmission device, the electric motor, internal combustion engine, or other high speed operating of power on the input shaft of the reducer gear of big gear on the output shaft gear mesh less to achieve the purpose of deceleration, ordinary there is few on the same principle of gear reducer and achieve ideal reduction effect, the size of the ratio of the number of teeth on the gears, transmission ratio. Reducer industry development in our country history for nearly 40 years, in the various fields of national economy and national defense industry, reducer products have a wide range of applications. Food, electricity, machinery, construction machinery, metallurgy, machinery, cement machinery, environmental protection machinery, electronic appliances, machinery, water conservancy machinery, chemical machinery, mining machinery, transportation machinery, building materials machinery, rubber machinery, petroleum machinery and other industries for reducer product has strong demand. Reducer is a relatively sophisticated machinery, and reducer in use often face all sorts of problems, among them, one of which is the bearing chamber wear. Reducer bearing chamber wear cause analysis 1, daily maintenance does not reach the designated position, leading to the casing of the lubricating oil system of impurities deposition is more, the equipment once these impurities in the process of running into horizontal installation of the high-speed shaft bearing raceway bearing accident jammed; 2, equipment operating characteristics, frequent start or point moving astern, is one of the causes of the high speed shaft vibration seriously; 3, reducer casing material problem, because of the speed reducer box body is composed of integral casting processing, local material without heat treatment and surface treatment etc, in the process of the equipment in the long run due to the fit precision problem between the components, the gear meshing vibration problem, start, stop the impact of vibration causes such as the wear of the bearing chamber. Once appear wear gap will accelerate the wear of the bearing chamber wear in a short time. According to our repair plan and combined with the actual situation on site and determine the repair process steps, using the bearing chamber did not wear datum, using blade feet along the datum for coating process. 1, to repair the bearing chamber for the first time to bake oil processing; 2, use polishing machine grinding wheel to deepen the worn parts with grinding process; 3, clear the burr on the datum and high; 4, with acetylene flame oil in bearing chamber and the second time for baking treatment ( The main purpose is bearing chamber heating) ; 5, use polishing machine grinding wheel tablets in bearing chamber after heating surface polishing treatment; 6, using anhydrous ethanol to repair the surface of cleaning; 7, with a sample rushed on polished surface pitting enhance surface sticky relay; 8, mixed right amount daub SD7101H material and blade feet along the datum blade coating; 9, finish coating material of bearing chamber with iodine tungsten lamp on the heating after curing process; 10 and curing of the bearing chamber with bearing ring grinding processing; 11, cooperate with the case on back pack process, use sand paper to curing material surface roughening treatment after clean with alcohol, secondary daub materials with high speed shaft to return to the group.
