The role of the coupling and several different couplings

　　Couplings belong to the category of general mechanical parts. They are used to connect two shafts (active shaft and driven shaft) in different mechanisms to rotate together to transmit torque. In the high-speed and heavy-duty power transmission, some joints The shaft device also has the function of buffering, damping and improving the dynamic performance of the shafting. The coupling is composed of two halves, which are respectively connected with the driving shaft and the driven shaft. Generally, the power machine is mostly connected with the working machine by means of a coupling. It is the main component of the shaft transmission of mechanical products.
　　In mechanical transmission, power machines are nothing more than electric motors, internal combustion engines and steam turbines. Due to the different working principles and structures of power machines, their mechanical characteristics are very different. Some run smoothly, and some have shocks during operation, which have unequal effects on the transmission system. , The mechanical characteristics of the power machine have an impact on the entire transmission system. For different types of power machines, due to their different mechanical characteristics, the corresponding power machine coefficient KW should be selected and the best coupling suitable for the system should be selected.
　　The type of power machine is the basic factor to choose the type of coupling.Between the power machine and the working time, the main and the driven ends are connected through one or several couplings of different varieties or different types and specifications to form a shaft transmission system, and the couplings are used to drive the motor group to work normally.
　　In the high-speed and heavy-duty power transmission, some couplings also have the function of buffering, damping and improving the dynamic performance of the shafting.The coupling is composed of two halves, which are respectively connected with the driving shaft and the driven shaft.The general power machine is mostly connected with the action machine by means of a coupling, which is a commonly used coupling component for the shaft transmission of mechanical products.Couplings belong to the category of general mechanical parts, which are mechanical parts used to connect two shafts (the driving shaft and the driven shaft) in different mechanisms so that they can rotate together to transmit torque.
　　Rigid coupling: Rigid coupling has high rigidity.
　　Elastic coupling: The elastic coupling has high rigidity and can absorb large installation errors.
　　Tire coupling: It has good damping and buffering and superior performance of offset compensation between shafts. The working temperature is -20~80 degrees Celsius, and the transmission torque is 10~20000N.M. It starts from humidity, dust, shock, vibration, The working conditions of positive and negative changes and frequent starting, and easy to disassemble, because the elastic element is an integral tire body, it is convenient to disassemble and maintain, does not need lubrication, and is durable and reliable.
　　Micro-coupling: The micro-coupling has a small volume, and at the same time possesses rigidity and flexibility, which can be used in precision micro-mechanical occasions.
