Reducer general used for low speed high torque transmission device, the electric motor, internal combustion engine, or other high speed operating of power after a few teeth reducer input shaft of big gear on the output shaft gear mesh reduction achieved to ordinary there is few on the same principle of gear reducer and reach the ideal slowing effect, the size of the ratio of the number of teeth on the gears, transmission ratio.
Reducer industry in our country to carry out the history for nearly 40 years, each category in the national economy and defence industry, speed reducer product has a widespread application.
Food, electricity, machinery, construction machinery, metallurgy, machinery, cement machinery, environmental protection machinery, electronic appliances, machinery, hydraulic machinery, chemical machinery, mining machinery, walks, building materials machinery, rubber machinery, petroleum machinery industry category for reducer product has strong demand.
Reducer is a relatively sophisticated machinery, and often face all kinds of problems in use of the gearbox, among them, one of which is the bearing chamber wear.
Reducer bearing chamber wear reason analysis of 1, daily maintenance of the inadequate care, cause the casing smooth oil system of impurities accumulated, equipment once these impurities in the process of running into horizontal device of high speed shaft bearing raceway formation bearing any card to death;
2, equipment operating characteristics, frequent start or spot moving astern is formed, such as one of the cause 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, part of the material without heat treatment or disposal, such as equipment in the process of long-term operation due to the fit precision problem between the parts, gear meshing vibration problem, start to suspend the formation of the impact vibration reason forming the wear of the bearing chamber.
Once present wear gap will accelerate the wear of the bearing chamber wear in a short time.
According to the condition of our repair plan and separation field practice must repair process steps, the application of the bearing chamber did not wear datum, with blade feet along the datum to stop coating process.
1, for fixing the bearing chamber to stop the first time to bake oil disposal;
2, use polishing machine grinding wheel piece of wear parts stop deepen burnish disposal;
3, clean up the burr on the datum and high;
4, with acetylene flame oil in bearing chamber and the second time to stop the roast disposal (
The main purpose is bearing chamber heating)
；
5, use polishing machine grinding wheel bearing outdoor table after the heat stop grind the disposal;
6, look with anhydrous ethanol repair looks to stop cleaning;
7, with a sample rushed in polished appearance to stop pitting strengthening appearance sticky relay;
8, mixed right amount SD7101H data to stop using edge daub feet along the datum blade coating;
9, finish coating materials bearing chamber with iodine tungsten lamp to stop the heating after curing treatment;
10, curing stop bearing chamber with bearing ring grinding treatment;
Case on 11, cooperate with the back pack process, use sand paper to stop coarsening of curing material appearance clean with alcohol after disposal, the secondary data with high speed shaft to return to the group.
