1. Start the main motor and grind in the forward and reverse directions.During the grinding process, since the wear of the abrasive is quite fast, it is necessary to apply the abrasive to the gear from time to time to observe the change of the tooth surface.When the meshing contact area of the gear reaches the level along the tooth length, tooth height, and smoothness, stop grinding and grind the gear.After grinding, use kerosene to carefully and thoroughly clean the abrasives on the internal parts of the reducer, such as bearings, gears, gear shafts, etc.
2. Disassemble the main shaft coupling and upper cover of the precision planetary reducer, remove the lubricating oil of the reducer, wipe all the gears with cotton yarn, and block the climbing parts of each bearing with asbestos boards to prevent impurities such as abrasives from entering and damaging the bearings. Use a polishing machine to smooth the high point of the convex tooth surface, use an electric file to polish the concave tooth surface, mix Nanjing Shanghai emery, white lead oil and appropriate amount of engine oil into a paste, and apply it evenly on all gear pairs with a brush.
3. Afterwards, clean all parts and boxes with cotton yarn and dough to prevent residual abrasives from accelerating gear wear and damaging bearings in subsequent operations.Use the wire side to measure the meshing clearance of the repaired gear, and make a record.Install the upper cover of the reducer to seal the joint surface to prevent oil leakage.Put on the main coupling and remove the textured collar.
4. Then perform a test run.First run at half speed with no load, then run at full speed with no load, and then run at half load and full load respectively.The entire run time is approx.When no problem is found, the gear repair work of the reducer is over.
