1. When removing the protective cover of each part, when dismantling the motor and brake wire, make a mark when disassembling the wire, as a reference for reassembly.
2. Remove the column pin of the high-speed shaft coupling of the cylindrical gear reducer, untie the toothed coupling of the low-speed shaft, and move the two halves of the coupling to both sides.Before disassembling the couplings of the high and low speed shafts of the reducer, the relative positions must be marked with a flat shovel or a sample punch, as the basis for the relative positions of the couplings.
3. Remove the anchor bolts of the motor and hang down the motor.When removing the anchor bolts of the motor, record the thickness and position of the original anchor gaskets as a basis for alignment.Loosen the brake anchor bolts, remove the brake adjusting screw, disassemble the brake, and remove the brake.
4. Remove the backstop of the reducer and place it in the designated position to avoid bumping.
5. Mark the relative position of the upper and lower joint surfaces of the reducer, remove the fastening bolts on the joint surface of the upper and lower covers of the reducer, replace the damaged bolts, and remove the positioning pins.Check whether the bolts are damaged or damaged, and screw the nuts onto the screw rods for safekeeping.
6. Put assembly marks on each bearing end cover, remove the fastening bolts of the bearing end cover, take off the end cover, measure the thickness and number of asbestos gaskets on the bearing end cover with an outer micrometer, and make original records.Preliminary inspection of the bearing end cover, the straight end face is free from wear and cracks.
7. Before lifting the upper cover, check whether there are missing screws or other abnormal phenomena.
