There are many functions of the motor shell, but the primary work content is to keep the shell dry. For details, please listen to the introduction of the motor shell manufacturer.
In the first mechanical aspect of the inspection, such as the rotating shaft, the flexible front motor housing, the bearing should be properly lubricated, the fan and the wind guide cover should not collide, the motor base fixed rate, etc. then the circuit must be checked and whether the motor lead wire is connected to. The motor runs for quite a long time and can be disassembled for maintenance. The use environment should always be dry, the motor surface should be kept clean, the air inlet should not be affected by dust, fiber and other obstacles.
The motor shell casting is not a very complete cylinder, and there are many auxiliary structures such as laps on the cylinder body. The wall thickness of each part of the casting changes greatly. The stress of the casting during cooling and solidification is also relatively large. The deformation tendency of the casting can not be accurately predicted before. The diameter difference of the end of the straight cylinder is 15 mm, and the ellipse is serious. The diameter error of the end of the straight cylinder is less than 1 mm by setting the ring-shaped reinforcement at the end of the straight cylinder.
The manufacturer of the motor case said that when the thermal protection and continuous action short-circuit protection of the motor, the set value of the motor or overload or protection device should be used to determine that the fault is too low. After the fault is eliminated, it can be put into operation. According to the wiring diagram connected to the power line connector, it is connected to a fastening, resulting in insulation and sealing of wire, cable, motor, and power line connection joint directly. The thickness of the motor casing is 4mm circular ring. One of its functions is to support and fix the motor, and the other is to repair the motor rotor so that the rotor can rotate smoothly. 7h - 3xm5 threaded holes are distributed at both ends of the part to install and fix the end cover. When machining the hole diameter of the electric shell, the turning tool should be aligned with the center of the workpiece. When machining the motor shell with high or low pressure, the deflection force will increase, which will affect the stability of the motor shell processing and speed up the tool wear. When machining the motor shell, it is better to operate in the same direction, reverse conversion and forward rotation processing. If there is less rough turning left, there will be one side of the first tool finishing turning, so a little more margin will be reserved for semi finishing turning and finishing turning. If the machine tool stops at low speed and changes to high speed, the above situation will also occur. Therefore, it is necessary to avoid the failure and ensure the concentricity. It is necessary to reserve the allowance for semi finish turning and finish turning, so as to avoid the alternative processing of positive and reverse rotation and the differential processing with too high rotating speed in the processing process. Machine tool processing performance and other factors. Ensure good concentricity and process the motor shell.
The quality of motor shell casting mainly includes appearance quality, external quality and application quality. Appearance quality refers to surface finish, appearance defect, dimension deviation, style deviation and weight deviation of castings; external quality mainly refers to chemical composition, physical properties, mechanical properties, metallographic groups, as well as holes, cracks, doping, segregation and other conditions existing in the castings; application quality refers to the long-term experience of castings under different conditions, including wear resistance Corrosion resistance, cold and heat resistance, fatigue, shock absorption and other performance, as well as grindability, weldability and other process properties.
The reasons affecting the accuracy of motor shell are as follows:
1. In the process of machining, because the cylinder parts belong to the thin-walled sleeve parts, the clamping rigidity and processing rigidity are poor, and it is easy to produce vibration, resulting in some size out of tolerance;
2. The failure of the cooling system of the machine tool leads to the continuous high temperature and thermal deformation of the workpiece in the process of processing;
3. There are some problems in the bearing of machine tool spindle, and the vibration is severe, which affects the dimensional accuracy;
4. The inner hole depth is longer, the tool extension length is too long, and there is no appropriate clamping system, which leads to the chatter marks on the inner hole surface.
