In life, when we encounter a broken motor, we want to disassemble it. What should we do? Now let the motor manufacturer tell you.
(1) First remove the external wiring of the motor and make a mark. For example, for an asynchronous motor, the mark corresponding to the three-phase power line should be made. For a DC motor, the shunt winding, armature winding, etc. should be made separately. The mark corresponding to the external wiring. Then loosen the foot screws to separate the motor from the transmission mechanism.
(2) Use the tools shown to disassemble the pulley or coupling on the motor shaft. Sometimes it is necessary to add some kerosene to the gap between the motor shaft of the pulley to penetrate and lubricate it for easy disassembly. Some shafts and wheels are tightly matched, and the wheels need to be heated quickly (while covering the shaft with a damp cloth) before the wheels can be removed.
(3) For motors equipped with rolling bearings, first remove the bearing outer cover, then loosen the fastening screws of the end cover, and mark the joints between the end cover and the housing shell (the front and rear end covers The marks should not be the same), screw the removed screws to fasten the end cover into the two specially set screw holes on the end cover of the motor, and push the end cover out. For motors without such screw holes, you can only use a chisel (also called a flat shovel) and a hammer to hit the joint between the end cover and the base to remove the end cover from the base. If the end cap is heavy, use lifting equipment to lift the end cap and remove it gradually.
(4) When disassembling a motor with a brush, the brush should be taken out of the brush holder, and the position of the neutral wire of the brush should be marked when removing the DC motor.
(5) When pulling out the rotor, you must be careful not to damage the stator coil. If the rotor is not heavy, you can pull it out by hand; if the weight is heavier, you should use lifting equipment to lift it out. See Figure 1-4 for the overwork steps. Show. First put both ends of the rotor shaft with a lifting wire rope to hang the rotor with a lifting device, and slowly move it out, taking care to prevent damage to the coil. Then put a steel pipe on one end of the shaft. In order to prevent the steel pipe from scratching the journal, the steel pipe can be lined with a layer of thick cardboard to continue to move the rotor out gradually. Put a bracket under it and put the steel wire rope in the middle of the rotor to pull out all the rotor.
The company adopts domestic advanced casting technology and mechanical processing equipment and technology.
