Synchronous Motor Pulley

Installation and fixing method of synchronous motor pulley

Jacking wire + horizontal fixation:

In a common way, the jacking wire is pressed and leveled to transmit torque, which can not bear large torque and frequent forward and reverse rotation. The jacking wire will loose and slip out, and scratch the synchronous belt. Moreover, the burr at the top screw hole of some poor quality synchronous wheels is not removed completely, resulting in serious wear of the synchronous belt and fracture in a short time. Suitable for light load and low speed.

Jacking wire + flat key fixation:

Compared with the first method, the jackscrew hole has not changed, and the risk points of jackscrew sliding out and orifice burr still exist. However, due to the flat key, it can drive large torque and high speed. It can slightly apply low viscosity screw glue, improve the processing quality of jackscrew hole and reduce the failure rate. It should be noted that the tolerance between the key and the keyway must refer to the national standard tolerance. The general fit or tight fit (or refer to MSM, the same). The clearance fit will produce impact during forward and reverse rotation, which will soon damage the keyway of the synchronous wheel.

The synchronous motor pulley is a transmission mechanism installed on the motor shaft. It is generally made of 45 × steel, aluminum alloy, copper, nylon and other materials. Because it has the advantages of accurate transmission, stable transmission, high transmission efficiency and convenient maintenance, it is widely used in the new mechanical belt transmission of machine tools, textiles, printing, food packaging, wires and cables, instruments and meters, petrochemical, tobacco, communications and other industries.

At present, when assembling the synchronous wheel of the motor, the commonly used operation method is: first assemble the stator and rotor respectively, and then install the synchronous wheel to the protruding part of the motor stator shaft by using the press fitting machine. This operation method requires that the synchronous wheel be manually taken and placed on the motor stator shaft in the vehicle, and then press the switch to start the machine to press and sleeve the synchronous wheel, and then remove it. When the synchronous wheel is manually placed, The synchronous motor pulley will be tilted due to the fatigue caused by people working for a long time, and the quality of the finished motor will be unstable, which makes the labor intensity of workers high and the efficiency low.
