The essentials of coupling selection:

①Permissible rated torque-is the allowable value of torque that the coupling bears during actual use.

② Allowable high torque-is the maximum critical value for coupling damage during use.

③Allow high speed-It is necessary to make sure that the speed of the motor is within this range when selecting the model.

④ Allowable eccentricity-the allowable value of the parallel deviation of the axis of the two shafts.

⑤ Allowable deflection angle-allowable value of mutual angle formed between two shafts.

⑥ Allowable axial deviation-the allowable value of the displacement of the two shafts in the axial direction.

When starting, stopping, and switching between forward and reverse rotations, the motor will apply a load greater than the large torque of the motor to the coupling. Therefore, when selecting the coupling, the rated torque of the coupling should be greater than the large torque of the motor.

Coupling is a mechanical part used to connect two shafts (active shaft and driven shaft) in different mechanisms to rotate together to transmit torque. In high-speed and heavy-duty power transmission, some coupling factories also have the function of buffering, damping and improving the dynamic performance of the shafting. The performance of the coupling consists of two halves, which are respectively connected with the driving shaft and the driven shaft. The general power machine is mostly connected with the working machine by means of a coupling. Coupling equipment, therefore, sometimes in the process of installing the coupling, we have to pay attention to the deviation in the process of connecting the shaft to the shaft.

It has a beautiful surface and good corrosion resistance. It does not need to go through the surface treatment such as plating, and exerts its inherent surface performance. A kind of steel in many aspects, usually called stainless steel. High alloy steels such as 13 chromium steel and 18-chromium nickel steel are representative of performance. From the perspective of metallography, because stainless steel contains chromium, a very thin chromium film is formed on the surface. This film isolates the oxygen from the intrusion of the steel and acts as a corrosion resistance.
