Coupling is a device that connects two shafts or shafts and rotating parts and rotates together without disengaging during the transmission of motion and torque. It does not change the direction of rotation and the size of torque during transmission. The common function of the shaft. The elastic coupling also has different levels of shock absorption and buffering functions, and the safety coupling also has overload safety protection functions.

 

Electricity is a great discovery. It is having a profound impact on our lives. How to convert electricity into other capabilities is a very complicated task. The coupling can convert electricity into kinetic energy and input energy for the operation of mechanical equipment. It is also a very important transmission component.

How to classify the coupling? What are the types of couplings?

 

Today we will not discuss the detailed classification of couplings. Let’s first understand some general directions of couplings. First, we will clarify this, and then we will make it easier to believe the classification.

 

1. Rigid coupling: It can only transfer motion and torque and has no other functions. The commonly used rigid couplings are: flange coupling, jacket coupling, etc.;
2. Flexible couplings: flexible couplings with no elastic components, flexible couplings with metal elastic components, flexible couplings with non-metallic elastics, etc.;
A. Flexible couplings without elastic components: not only can transmit motion and torque, but also have different degrees of axial, radial, and angular compensation functions. Commonly used flexible couplings with elastic components are: toothed Couplings, universal couplings, chain couplings, slider couplings, etc.;
B. Flexible couplings with metal elastic elements: Non-metallic flexible couplings, which can transmit motion and torque, have different degrees of shock absorption, buffering and compensation, and improve the performance of the transmission system. Commonly used flexible couplings of metal elastic elements are: diaphragm coupling, serpentine spring coupling, etc. Commonly used non-metallic elastic flexible couplings: elastic pin couplings, plum blossom couplings, elastic pin bushing couplings, tire couplings, etc.;
C. Non-metallic flexible coupling: This type of coupling is made of rubber, polyurethane and nylon. Compared with metal materials, non-metallic materials such as rubber have the following advantages: large elastic modulus range makes it easy to obtain elastic elements with different stiffness, light weight, large internal friction, good damping performance, more deformation energy per unit volume storage, no mechanical friction, No lubrication, etc.;
D. Safety coupling: It has the functions of transmitting motion and torque, overload safety protection, and flexible safety coupling has different degrees of compensation performance. Commonly used safety couplings are: steel ball type, hydraulic type, friction type, etc.

 

Compared with rigid couplings, flexible couplings cover a much wider range. The actual ones we have come into contact with, such as plum blossom couplings, elastic stud couplings, diaphragm couplings, etc., are all under its control. A member. The flange coupling in the rigid coupling is the original form of all couplings, and other couplings are evolved through it.
