In the overhaul of the large reducer, the pre-construction preparations include: (1) cleaning the working site of the crane and trailer required for the hoisting reducer, removing all the accessories and spare materials stacked on site, and ensuring that the large equipment is hoisted. Enough safe working space. (2) Clean the auxiliary working environment, the main motor and the working environment around the main reducer, and clear the oil and other debris in the anchor box of the main motor and main reducer. (3) Clean up the material accumulated in the raw material vertical grinding disc, the lower space of the center cover, the pressure frame, the top support of the hydraulic tensioning device and the pressure frame connection, and the hot air chamber. (4) Processing and making tooling, and preparing tools. Subsequent removal work can be carried out after checking that the mark is correct. Remove the auxiliary equipment such as the reducer thermometer and pressure gauge, and keep small parts. Cut off all the switches of the raw material vertical grinding and protect them (preferably chain), remove the main transmission, auxiliary transmission and oil pump to central control insurance; cut off all driving power; remove the oil passage inlet and outlet of the reducer and all power pipes and lines, pay attention to Make a mark. Clean up the main and auxiliary anchor bolts, and mark and classify the bolts around the place for easy reloading. The diaphragms are integrally joined by four bolts using the four process holes at both ends of the diaphragm coupling, and then the diaphragm coupling is lifted horizontally and the connecting bolts are removed. It is necessary to prevent deformation of the diaphragm during removal. Remove and hoist the main transmission motor, auxiliary transmission and its steel base, and mark the horn under the base. After the main transmission motor and the auxiliary transmission motor are lifted, reasonable support (such as sleepers) and rainproof and moisture proof measures are required. Open the center cover of the disc holder and remove the 12 connecting bolts of the output flange of the reducer and the disc holder. Note that you do not need to dial the two pins on the side.
