Disassembly of cylindrical gear reducer
The cylindrical gear reducer has been working for a long time. It is necessary to disassemble the cylindrical gear reducer to check whether there are common faults in the equipment. It must be repaired, so that the cylindrical gear reducer can be maintained in normal operation. The internal structure can be clearly seen by disassembling the machine and equipment, so that purposeful maintenance can be carried out to ensure that the cylindrical gear reducer can operate smoothly for a long time. The process is as follows:
First of all: In the case of removing the protective cover at each position, and removing the motor and braking system, it must be noted that when removing the line, make a mark as a reference for reassembly.
Step 2: Remove the pin of the high-speed shaft coupling of chinese gearbox manufacturer
the cylindrical gear reducer, release the low-speed shaft toothed coupling, and remove the two couplings to both sides. Before removing the high and low gear shaft couplings of the reducer, be sure to mark the relative position with a shovel or a sample punch, as a basis for the relative position of the coupling reassembly.
Step 3: Remove the motor anchor screws and hang down the motor. When removing the motor anchor screws, record the thickness and position of the initial seat gasket as a basis for finding the engine timing. Loosen the anchor screw of the braking system, remove the adjusting ball screw of the braking system, dismantle the braking system, and remove the braking system.
Step 4: Remove the reducer backstop and place it in a specific part to prevent bumping.
Step 5: Mark the relative position of the upper and lower fusion surfaces of the reducer, remove the fusion surfaces of the left and right covers of the reducer and tighten the anchor bolts, remove the damaged anchor bolts, and remove the positioning pins. Check whether the anchor bolts are incomplete or cracked, and screw the screw cap onto the extruder screw for proper storage.
Step 6: Mark the installation marks on the end caps of each rolling bearing, remove the end caps of the rolling bearing and tighten the anchor bolts, remove the end caps of the bearing, and use an inner micrometer to accurately measure the thickness and quantity of the asbestos gaskets of the end caps of the rolling bearing. Original record of the experiment. Basic inspection of the bearing end cover of the rolling bearing, no wear or cracks in the inner hole of the straight mouth.
Step 7: Before lifting the top cover, check whether there are any missing screws and other abnormal conditions (use the butt fastener to lift the top cover, hoist it to the prepared pad, and the crane actually operates Licensed to work). Note: Please mark the initial meshing part of the transmission gear, and mesh in the original order when reassembling.
The disassembly of the cylindrical gear reducer should be carried out in accordance with the process, and the opposite components should be placed in a specific position to avoid wrong assembly, missing assembly or loss in the case of assembly.
Disassembly sequence of cylindrical gear reducer
In the cylindrical gear reducer, the upper and lower casings are connected according to six anchor bolts. Remove the six anchor bolts, and then screw the anchor bolts slightly to lift the upper casing. Lose. Regarding the parts on the two shafts, all the shafts can be taken out, and each part can be removed one by speed reducer manufacturer
one. The disassembly of other parts is very simple and has not been described. When installing, it is usually reversed back, the parts that are removed after the installation are installed first, and the parts that are removed first are installed after the installation can be completed.
When unloading parts of cylindrical gear reducer, be careful not to knock with hard objects indiscriminately, to prevent knocking on parts and jeopardizing installation and repair. Parts that are not easy to disassemble, such as parts with joint cooperation or interference cooperation, do not have to be very easy to remove. The dismantled parts should be stored properly, preferably in the same direction in order to prevent them from being discarded or difficult to install.
