Universal coupling connection and basic principle

Introduction:

Due to the manufacturing and installation errors, deformation after bearing and the influence of temperature change, the two axes connected by the universal coupling will cause the change of the relative position of the two axes, and often can not ensure the strict alignment. According to whether the universal coupling has elastic components, whether it has compensation ability for various relative displacement, that is, whether it can maintain the connection function under the condition of relative displacement and the use of the coupling, the coupling can be divided into rigid coupling, flexible coupling and safety coupling. The main types, characteristics and functions of couplings in the transmission system. Rigid coupling can only transfer motion and torque, do not have other functions including flange coupling, sleeve coupling, clamp coupling and so on.

Types of universal coupling:

Flexible coupling without elastic components, not only can transfer motion and torque, but also has different degrees of axial, radial, angular compensation performance including gear coupling, universal coupling, chain coupling, sliding block coupling, etc. Flexible coupling with elastic element to transmit motion and torque; With different degrees of axial, radial, angular compensation performance; Also has different degrees of damping, buffering effect, improve the performance of the transmission system including a variety of non-metallic elastic components flexible coupling and flexible metal elastic components, a variety of elastic coupling structure is different, the difference is large, the role of the transmission system is not the same. Safety coupling transmits motion and torque for overload safety protection. Flexible safety coupling also has different degrees of compensation performance including pin type, friction type, magnetic powder type, centrifugal type, hydraulic type and other safety coupling.

The composition of universal coupling:

A universal coupling is a mechanical part used to connect two shafts in different mechanisms to rotate together to transfer torque. In high speed and heavy load power transmission, some couplings also play the role of cushioning, damping and improving the dynamic performance of shafting. A universal coupling consists of two halves connected with the drive shaft and the driven shaft respectively. The general engine is connected with the working machine mostly by means of coupling. Therefore, sometimes in the process of installing the coupling, we should also pay attention to the deviation in the process of connecting the shaft to the shaft. A universal coupling consists of two halves connected with the drive shaft and the driven shaft respectively. The general engine is connected with the working machine mostly by means of coupling.

To sum up:

So sometimes in the process of installing the coupling we should also pay attention to the deviation of the shaft and shaft connection process has a beautiful surface and good corrosion resistance, do not have to go through plating and other surface treatment, and play the inherent surface performance, used in many aspects of the steel, usually known as stainless steel. Representative properties of 13 chromium steel, 18- chromium - nickel steel and other high alloy steel. Because stainless steel contains chromium, so that the surface of the formation of a very thin chromium film, this film is separated from the invasion of oxygen in the steel to act as a corrosion resistance. In order to implement the basic universal standard chain coupling is the use of public chain, at the same time in two teeth the same number of parallel sprocket meshing, different structure of the chain coupling is the main difference is the use of different chains, common double row roller chain coupling, single row roller chain coupling, toothed chain coupling, nylon chain coupling.
