Motor housing assembly structure

This creation is a motor housing assembly structure, especially one that can quickly assemble the motor casing without tools, and can also quickly disassemble the casing for maintenance, which is convenient for combination maintenance and cost reduction.

The basic structure of the motor is composed of a permanent magnet, a rotor composed of a rotating shaft, and a stator composed of an electromagnetic coil. When the stator formed by the electromagnetic coil receives a power source and generates a magnetic phase change, the rotor can be driven to rotate and pass through the rotating shaft. Drive to output power.

In order to prevent the rotor from being obstructed when rotating, and to minimize the loss of power due to friction during rotation of the rotor, the rotor and the stator are disposed in a cylindrical casing for dustproofing, and ball bearings are provided at both ends or at one end of the casing. The rotor shaft passes through to output power, so that the rotor can maintain the best output efficiency as much as possible.

As mentioned above, since the rotor is driven by the magnetic coil to receive the power supply, the magnetic phase change is driven, and the power loss must be minimized during the rotation of the rotor. During the operation, the precision of the electromagnetic coil manufacturing process and the ball on the outer casing. The external factors such as the accuracy of the bearing at the positive center of the electromagnetic coil affect the output efficiency of the rotor, so that the finished motor must undergo rigorous testing to ensure its quality.

As shown in the first figure, in order to facilitate assembly, a conventional outer casing is composed of an upper casing 1 and a lower casing 2, and the upper casing 1 and the lower casing 2 are correspondingly joined to form an accommodating space therein for The rotor and the stator are installed, wherein the upper shell 1 and the lower shell 2 are respectively provided with a plurality of array lugs 3 on the corresponding joint edges, and each of the corresponding lugs 3 is provided with a screw hole 4 coaxially arranged to enable the screw 5 to be locked In the two screw holes 4, the upper shell 1 and the lower shell 2 are joined to each other to prevent dust or foreign matter from entering. If the motor is to be corrected and repaired, the screw 5 can be unlocked and the housing can be disassembled for maintenance correction.

However, the stator and rotor shafts of each group of motors may not be accurately controlled at the center point, so that the motor is prone to some vibration when running. When the motor is running for a long time, it is easy to loosen the vibration of the screw, so that the upper and lower shells fail. Maintaining a close state affects the output efficiency of the motor.

As shown in the second figure, another conventional housing is formed by punching or riveting the corresponding engaging edges of the upper casing 1 and the lower casing 2 in the form of lugs 3, in order to prevent vibration from being generated when the motor is running to loosen the screws. The missing, can eliminate the alignment of the upper and lower shell screw holes, and the assembly steps of the locking screws, reducing manufacturing man-hours. However, in this method, after the upper shell and the lower shell are combined with each other and punched or riveted and fixed, the disassembly cannot be repeated, and the position of the center point of the motor stator and the rotor cannot be corrected. If the components inside the motor are damaged, Repair it.

More importantly, as mentioned above, the rotor and stator will be affected by various factors, and if the output of the motor is not used as expected after the test, even if it is used for a period of time, it is often necessary to disassemble the casing. By examining its internal structure, it is possible to find out the cause to avoid similar problems with other motors. If it is necessary to repair, it is necessary to disassemble the outer casing to replace the internal parts. As a result, the above-mentioned conventional casing combined by screw or stamping is obvious.
