Summary:...
The specific operation method is to disassemble the main shaft coupling, uncover the upper cover of the
planetary gearbox, and discharge the lubricating oil in the reducer. Wipe all gears clean with cotton gauze, and plug the climbing parts of all bearings with asbestos sheets. Strictly prevent abrasives and other impurities from invading and grinding the bearing. Use a denture machine to repair the high point of the convex tooth surface, and use an electric file to grind the concave tooth surface. Stir with white lead oil and appropriate amount of machine oil to form a paste. Apply them evenly to all gear pairs with a brush. Then start the main motor to grind forward and backward.
When the meshing contact area of the gear reaches the tooth length, tooth height and smoothness, stop grinding and grinding, carefully clean the internal parts of the planetary reducer such as bearings, gears and abrasives on the gear shaft with kerosene, and then clean it with cotton cloth and dough All parts and housings to prevent residual abrasives from accelerating gear wear, and use the lead wire side of the bearing to measure post-repair grinding gear mesh clearances in subsequent operations. And make a record of the upper cover of the planetary reducer, seal the joint surface, and prevent oil leakage.
After the finished coupling is removed, the ground collar of the car is removed, and then the running-in test is carried out. Run-in at half speed without load first, run-in at full speed without load, and then run-in with half load and full load. The whole run-in time is probably after checking that there is no problem, and the work of equipment repair will stop here.
