What factors should be considered when choosing a coupling?

Different industrial equipment has different requirements for transmission. Therefore, at this stage, the coupling manufacturers have many product varieties, specifications and models. Different couplings have their own characteristics and application fields. They must be selected according to the situation. What aspects should be considered when purchasing a coupling?
Whether the purchase of the coupling is suitable or not will immediately endanger a series of problems such as the operating conditions, vibration, and noise of the industrial equipment, so the selection of the coupling must fully consider all factors:

Coupling manufacturers

The mechanical equipment characteristics of the power machine:
The mechanical equipment characteristics of the power machine are harmful to all transmission devices. Different types of power machines have different mechanical equipment characteristics. The relative power machine index KW should be selected, and the best coupling suitable for the system software should be selected.The type of power machine is the basic element for selecting the type of coupling.The output power of the power machine is one of the key basis for confirming the specification, model and size of the coupling, which is proportional to the torque of the coupling.

Load type:

Because the structure of the machinery and equipment is different from the raw materials, the bearing capacity of the coupling used for the transmission of each machinery and equipment commodity is quite different.Load types are mainly used for different types of loads due to impact, vibration, forward overturning, braking system, and frequent starting of the load during the work of the working machine.Low-speed gears and light-load loads should prevent the use of couplings that are only suitable for small and medium-sized output power. Shafting systems with large load changes and impact and vibration should be selected. Elastic couplings with elastic elements and good buffer and shock absorption effects should be selected. Shaft.
Permissible speed of coupling:

The allowable speed range of the coupling is based on the larger edge specification of the allowable angular velocity of the different raw materials of the coupling, which is confirmed by calculation.The allowable speed range of couplings with different raw materials and types and specifications is different. Changing the raw material of the coupling can increase the allowable speed range of the coupling. The allowable speed of the raw material is steel and the allowable speed of the raw material is pig iron. .
Transmission accuracy of coupling:

Small torque and a shafting transmission dominated by fitness exercises require that the coupling has a high transmission accuracy, and a flexible coupling with a metal material elastic element should be used.The shafting transmission with large torque and transmission driving force also has regulations on the transmission accuracy. When rotating at high speeds, it is necessary to prevent the use of non-metallic elastic element elastic couplings and flexible couplings with gaps between moving components. It adopts a high-precision diaphragm coupling.

Coupling specifications, installation and maintenance:

The size of the coupling, that is, the larger axial and radial specifications, must be within the installation room space allowed by the mechanical equipment.Choose a coupling that is convenient for assembly and disassembly, does not require maintenance, has a long maintenance period or is convenient for maintenance, is easy to disassemble and replace without moving the two shafts, and is very easy to adjust for centering.
