The working principle and application of the coupling!

The function of the coupling is to connect the water pump shaft and the pump motor shaft to rotate together. Couplings are also called couplings, counter wheels, back wheels and so on. Common couplings include rigid couplings, elastic couplings, toothed couplings, hydraulic couplings, etc.

Working principle and application of coupling

1. Coupling function: It is used to connect the two shafts together. The two shafts cannot be separated when the machine is running. Only after the machine stops and the connection is disassembled can the two shafts be separated.

2. The type of coupling: the two shafts connected by the coupling, due to manufacturing and installation errors, deformation after loading, and the influence of temperature changes, will cause changes in the relative position of the two shafts, and strict alignment is often not guaranteed . According to whether the coupling has elastic elements, whether it has the ability to compensate for various relative displacements, that is, whether it can maintain the connection function under the condition of relative displacement, and the purpose of the coupling, etc., the coupling can be divided into rigid couplings, Flexible Couplings and Couplings.

The main types and characteristics of couplings and their role in the category of action in the transmission system. Rigid couplings--can only transmit motion and torque, and do not have other functions, including flange couplings, sleeve couplings, Shell couplings, etc. Flexible Couplings - flexible couplings without elastic elements, not only can transmit motion and torque, but also have different degrees of axial, radial and angular compensation performance, including gear couplings, universal joints Couplings, chain couplings, slider couplings, etc.

Flexible couplings with elastic elements can transmit motion and torque; have different degrees of axial, radial and angular compensation performance; also have different degrees of vibration reduction and buffering effects, and improve the working performance of the transmission system, including Various non-metal elastic element flexible couplings and metal elastic element flexible couplings have different structures and large differences, and their functions in the transmission system are also different. Couplings-- Transmission of motion and torque, overload protection.

Flexible couplings also have different degrees of compensation performance, including pin type, friction type, magnetic powder type, centrifugal type, hydraulic type, etc. Couplings are used to connect two shafts (driving shaft and driven shaft) in different mechanisms to make them Mechanical parts that rotate together to transmit torque. 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.
