Steps to remove the motor housing

Precision, dedicated to metal insert injection and precision metal stamping for more than ten years, we can produce customized stretch shells, motor connectors, ABS electromagnetic coil shells, etc. Welcome to consult. The motor housing has the function of protecting the motor and preventing various pollution, and the demand is increasing day by day. So, what should be done when the motor housing needs to be disassembled during use? Let's take a look at the steps. 1. For motors equipped with rolling bearings, first remove the bearing cover, then loosen the fastening screws of the end cover, and mark the joints between the end cover and the housing shell (marks of the front and rear end covers) Should not be the same), screw the removed screws that 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 cover is heavy, use a lifting device to lift the end cover and gradually remove it. 2. When pulling out the rotor, be careful not to damage the stator coil. If the weight of the rotor is small, you can pull it out by hand; if the weight is heavier, you should use lifting equipment to lift it out. Hang the rotor with a lifting device and slowly move it out, taking care to prevent damage to the coil. 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. When the weight/center of the rotor has moved to the outside of the stator, A bracket is placed under the shaft end, and the steel wire rope is placed in the middle of the rotor, and the rotor can be completely drawn out. 3. 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. Marking corresponding to the wiring. Then loosen the foot screws to separate the motor from the transmission mechanism. 4. Use tools to remove 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 make it penetrate and lubricate 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. 5. 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.
