Motor shafts are generally made of high-quality carbon steel. Generally, low-carbon steel is used, and its compressive strength, bending stiffness, and ductility can all be considered in the work requirements of the motor shaft. The motor shaft has a high-speed ratio and a small torque. It is made of low-carbon steel and does not require heat treatment. The raw material is quenched. The supply characteristics of the raw material can be considered for the physical properties of the motor shaft.
There are two types of motor shafts: optical shaft and web shaft. This depends on the size of the rotor hole shaft. Whether it is an optical shaft or a web shaft, the machining process is roughly the same. The transformer core gear is based on milling. The matching relationship between processing and the transformer core is mostly H7/k6. Naturally, this is also related to the torque assumed by the rotor. It can be obtained based on calculations and work experience. The shaft extension end of the motor is the position of the customer's socket. It needs to be polished, one is beautiful and generous, and after fine polishing The total area in contact with the coupling is large and the bearing capacity is symmetrical. The main purpose of the motor transmission torque can be considered, and the healthy groove must be processed by a milling machine. Generally speaking, the manufacturing process of the motor shaft is fine turning/piercing the management center hole-boring/reserving cutting capacity at the position that must be ground-cutting-cutting.
If the machining of the motor shaft is simple, it is a CNC lathe plus a CNC lathe, that is, milling and so on. Therefore, it is rarely used in machinery and equipment. The simple way to install the round wheel on the motor shaft is to make the internal thread of the round wheel exceed the diameter of the motor shaft, and then install it with heating. In the motor shaft processing, the reason for improving the smoothness of the surface layer is that it can increase the fatigue life of the motor shaft, thereby improving its service life, and improving its appearance and elegance. In addition, it can also improve the strength of the finished product after processing and its corrosion resistance.
