I'll teach you how to disassemble the motor housing


The disassembly methods of Dalian motor housing are as follows: (1) when the motor housing pulls out the rotor, attention must be paid not to damage the stator coil. If the rotor weight is small, it can be pulled out by hand; If the weight is large, it should be lifted out with lifting equipment. First, put the two ends of the rotor shaft with lifting wire rope, hang the rotor with lifting equipment, and move it out slowly. Junfei reminds you to avoid damaging the coil. (2) For the motor equipped with rolling bearings, remove the bearing outer cover first, then loosen the fastening screws of the end cover, mark the joint between the end cover and the base shell (the marks of the front and rear end covers should not be the same), screw the removed fastening screws of the end cover into the two specially set screw holes on the motor end cover, and push the end cover out. (3) Use tools to disassemble the pulley or coupling on the motor shaft. Sometimes, it is necessary to add some kerosene into the gap between the motor shafts of the pulley to make it permeable and lubricated for disassembly. (4) first remove the external wiring of the motor and make marks. For example, for asynchronous motor, the marks corresponding to the three-phase power line should be made. For DC motor, the marks corresponding to the external wiring such as shunt winding and armature winding should be made respectively. Then loosen the foot screws to separate the motor from the transmission machinery.


Properties decide to use pig iron instead of wrought iron: wrought iron is rarely used as a structural material because of its soft texture and low strength. The carbon in cast pig iron exists in the form of flake graphite, and its fracture is gray, which is usually called gray iron. Because graphite is soft and has lubricating effect, cast pig iron has good cutting, wear resistance and casting properties. However, its anti positional strength is not enough, so it can not be forged and rolled. It can only be used to manufacture various castings, such as casting various machine tool bed seats, iron pipes, etc. The carbon in nodular cast iron exists in the form of spherical graphite. Its mechanical properties are much better than gray iron and close to steel. It has excellent casting, machining and wear resistance, and has certain elasticity. It is widely used in manufacturing high-grade castings such as crankshaft, gear, piston and a variety of mechanical parts.
