  The two shafts connected by the universal coupling, due to manufacturing and installation deviations, load-bearing deformation and temperature changes, will cause the relative parts of the two shafts to change, and it is usually impossible to ensure strict alignment.According to whether the universal joint has elastic elements and whether it has the ability to compensate for various relative deviations, whether the connection function and the main purpose of the coupling can be maintained under the standard of relative deviation, etc. Shafts can be divided into rigid couplings, flexible couplings and safety couplings.The key types and characteristics of couplings and their efficiency in the transmission device.Rigid couplings only transmit fitness exercises and torque, and have no other functions. They include flange couplings, sleeve couplings, and clamp couplings.


  The flexible coupling without elastic elements can not only transmit fitness exercises and torque, but also have different levels of radial, axial, and angular compensation characteristics, including gear couplings, universal couplings, and chain couplings. Shafts, slider couplings, etc.The flexible coupling with elastic elements can transmit fitness exercises and torque; it has different levels of radial, axial, and angular compensation characteristics; it also has different levels of shock absorption and adjustment, improving the transmission device The working characteristics include a variety of non-metallic material flexible element flexible coupling and metal material flexible element flexible coupling. The structure of various flexible couplings is different, and the difference is very large. In the transmission device The efficacy of the different is also different.The safety coupling transmits fitness exercises and torque, and maintains load safety.Winding safety couplings also have different levels of compensation characteristics, including split pin, friction, magnetic powder, axial flow, hydraulic and other safety couplings.
Universal coupling


  Universal coupling is a mechanical component used to connect two shafts in different tissues so that they can rotate with each other to transmit torque.In the high-speed and light-load driving force transmission system, some couplings also have the functions of buffering, damping and improving the dynamic characteristics of the shafting.The universal joint is composed of two parts, which are respectively connected with the driving shaft and the driven shaft.Usually the power machine is mostly connected with the working machine by means of a coupling.Therefore, sometimes people have to pay attention to the errors in the whole process of shaft and shaft connection during the whole process of installing the coupling.The universal joint is composed of two parts, which are respectively connected with the driving shaft and the driven shaft.Usually the power machine is mostly connected with the working machine by means of a coupling.


  Therefore, sometimes in the whole process of installing the coupling, people should pay attention to the errors that occur in the whole process of shaft and shaft connection. It has beautiful surface and good corrosion resistance. It does not need to go through metal surface treatment such as plating, and give full play to all This kind of steel that has the characteristics of the surface layer, which is used in various aspects, is generally called stainless steel plate.It means that there are high alloy steels such as 13 chrome steel and 18-chrome nickel steel.Because the stainless steel plate contains chromium and the surface layer produces a too thin chromium film, this film isolates the intrusion of CO2 in the steel and acts as a corrosion resistance.In order to implement the basic universal specification of the coupling, the chain coupling uses a common transmission chain. In addition, the two side-by-side sprockets with the same number of teeth are engaged. The key difference between the chain couplings of different construction forms is the selection of different transmissions. Chains generally include single and double row roller chain couplings, single and double row roller chain couplings, toothed chain couplings, polyester chain couplings, etc.
