Limited moment type permanent magnet coupler manufacturers believe that the coupler is composed of two halves, and the two halves are connected with the driving shaft and the driven shaft. Most power machines are connected to working machines by couplers. The commonly used couplers are safety coupler, gear coupler, diaphragm coupler, slider coupler and so on.

Limited moment type permanent magnet coupler manufacturers believe that the coupler is used to connect two shafts in different mechanisms (the driving shaft and the driven shaft) to rotate together and transfer torque. Some couplers also have the function of buffering, damping and improving the dynamic performance of shafting.

In addition, the coupler is also used for power output, which is a universal device connecting the output shaft and the driven shaft. Not only that, the coupler will also drive the shaft output torque transfer to the driven mechanism, its main purpose is to facilitate installation and disassembly of maintenance.

Limited moment type permanent magnet coupler manufacturers think that the factors to be considered when choosing a coupler:

1. Mechanical characteristics of power machine. Limited moment type permanent magnet coupler manufacturers believe that between the power machine and the working machine, the active end and the driven end through one or several different types and specifications of couplers connected to form a shafting drive system. In mechanical transmission, power engines are nothing more than electric motors, internal combustion engines and gas turbines. Because the working principle and mechanism of the power machine are different, its mechanical characteristics are also very different, some run smoothly, some run from time to time, the impact on the transmission system is not equal. According to the mechanical characteristics of power machines, power machines are divided into four categories.

Limited moment type permanent magnet coupler manufacturers believe that the mechanical characteristics of the power machine has a certain impact on the whole transmission system. Because the mechanical characteristics of different types of power machine are different, the corresponding power machine coefficient Kw should be selected, and the coupler suitable for the system should be selected. The type of power machine is the basic factor to choose the type of coupler. The power of power machine is one of the main basis to determine the size of the coupler, which is proportional to the torque of the coupler. The power machine in the transmission system of fixed mechanical products is mostly motor, and the power machine in the transmission system of driving mechanical products (such as ships, various vehicles, etc.) is mostly motor. It's the internal combustion engine. When the engine is an internal combustion engine with different number of cylinders, the influence of torsional vibration on the transmission system is considered, which is related to the number of cylinders of the internal combustion engine and whether each cylinder works normally. At this time, the elastic coupler should be used to adjust the natural frequency of the shafting system, reduce the torsional vibration amplitude, in order to achieve vibration reduction, buffer and protection of transmission components, improve the performance of the middle, increase the output power stability.

2. Load category. Limiting moment type permanent magnet coupler manufacturers think that due to the different structure and material, various mechanical products in the transmission system used in the coupler bearing capacity difference is very big. The load category mainly refers to the different types of loads caused by the impact, vibration, positive and negative rotation, braking, frequent start and other reasons of the working load of the working machine. For the convenience of selection and calculation, the load of the transmission system is divided into four categories.

Limiting moment type permanent magnet coupler manufacturers think that the load category of the transmission system is the basic basis for choosing the type of coupler. For the impact, vibration and torque changes of the working load, should choose flexible coupler with elastic elements, namely elastic coupler, to buffer, reduce vibration, compensation axis deviation, improve the performance of the transmission system. Frequent start, reverse and brake torque is normal stable operation of several times, belongs to overload operation, will shorten the service life of elastic elements of the coupler. The coupler only allows short overloads. In general, short-term overload shall not exceed 2~3 times of rated torque.
