What are the factors to consider when choosing a coupler? Moment-limited permanent magnet coupler manufacturers explain for you

Moment-limited permanent magnet coupler manufacturers believe that the coupler consists of two halves, which are connected to the driving shaft and the driven shaft respectively. Most power machines are connected to working machines through couplers. Commonly used couplers include safety couplers, gear couplers, diaphragm couplers, and slider couplers.

Moment-limited permanent magnet coupler manufacturers believe that the coupler is used to connect two shafts (driving shaft and driven shaft) in different mechanisms to rotate together and transmit torque. Some couplers also have the function of buffering, damping and improving the dynamic performance of the shaft system.

In addition, the coupler is also used for power output and is a general device that connects the output shaft and the driven shaft. Not only that, the coupler also transmits the output torque of the shaft of the driving mechanism to the driven mechanism, the main purpose of which is to facilitate the maintenance of installation and disassembly.

Moment-limited permanent magnet coupler manufacturers believe that factors to be considered when selecting couplers:

1. The mechanical characteristics of the power machine. Moment-limited permanent magnet coupler manufacturers believe that between the power machine and the working machine, the driving end and the driven end are connected through one or several couplers of different types and specifications to form a shafting transmission system. In mechanical transmission, the power machine is nothing more than an electric motor, an internal combustion engine and a gas turbine. Due to the different working principles and mechanisms of the power machine, its mechanical characteristics are also very different. Some run smoothly, and some have shocks during operation, which have unequal effects on the transmission system. According to the mechanical characteristics of the power machine, the power machine is divided into four categories.

Moment-limited permanent magnet coupler manufacturers believe that the mechanical characteristics of the power machine have a certain impact on the entire transmission system. Due to the different mechanical characteristics of different types of power machines, 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 in selecting the type of coupler. The power of the power machine is one of the main bases for determining the size of the coupler, which is proportional to the torque of the coupler. The power machines in the transmission system of fixed mechanical products are mostly electric motors, and the power machines in the transmission system of driving mechanical products (such as ships, various vehicles, etc.) are mostly electric motors.) It's an internal combustion engine. When the power 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, elastic couplers should generally be used to adjust the natural frequency of the shaft system and reduce the torsional vibration amplitude to achieve vibration reduction, buffering and protection of transmission components, improve centering performance, and increase output power stability.

2. Load category. Moment-limited permanent magnet coupler manufacturers believe that due to different structures and materials, the load-bearing capacity of couplers used in various mechanical product transmission systems varies greatly. The load category mainly refers to the different types of loads caused by the impact, vibration, forward and reverse rotation, braking, frequent starting and other reasons of the working load of the working machine. In order to facilitate the selection and calculation, the load of the transmission system is divided into four categories.

Moment-limited permanent magnet coupler manufacturers believe that the load category of the transmission system is the basic basis for selecting the type of coupler. For working loads with large changes in impact, vibration and torque, flexible couplers with elastic elements, that is, elastic couplers, should be selected to buffer, reduce vibration, compensate axis deviation, and improve the working performance of the transmission system. The torque during frequent starting, forward and reverse rotation and braking is several times that of normal and stable operation, which belongs to overload operation and will inevitably shorten the service life of the elastic element of the coupler. The coupler allows only short-time overloads. In general, short-term overload shall not exceed 2 to 3 times the rated torque.
