Which material do you use for motor shaft machining?
- Jun 13, 2018 -

Motor shafts are usually made of high-quality carbon steel. 35#, 45#. 45# steel is usually used. These two materials belong to medium carbon steel, and their strength, stiffness and toughness can meet the working requirements of the motor shaft. The motor shaft has a high rotational speed and low torque. It is made of 45# without any other heat treatment. The normalization of raw materials, raw material supply capacity can meet the mechanical performance requirements of the motor shaft.

The motor shaft is divided into two major categories, the optical axis and the spoke shaft. This depends on the size of the shaft hole of the rotor of the motor. The addition process of the optical axis or the spoke shaft is generally the same, and is the same on the core file. Through the turning machining, the cooperation relationship with the core is mostly H7/k6.

Of course, this also depends on the torque that the rotor of the motor is subjected to. Based on calculations and experience, the shaft extension end of the motor is the part that interfaces with the customer. It is necessary to carry out grinding, one must be beautiful, and the other must be refined. The coupling has a large contact area and can be used evenly to meet the purpose of motor torque transmission. The keyway needs milling machine processing. In general, the machining process of the motor shaft is: roughing/drilling center hole-finishing/requiring ground grinding margins-grinding-milling. Choose high-quality motor shafts and look for Ti-Hao. Professional quality guarantee! Because of the profession, so excellent!

The motor shaft machining, if it is simple, is the processing of a lathe plus a milling machine, that is, turning and the like. Therefore, there are not many of them using the equipment. The simple method of mounting the disk on the motor shaft is to make the inner diameter of the disk larger than the diameter of the motor shaft and then heat the assembly. The reason for improving the surface smoothness of motor shaft machining is that it can increase the fatigue life of the motor shaft, thereby improving its service life, and improving its appearance and appearance. At the same time, it can also improve the hardness of finished products after processing and their corrosion resistance.
