All about jaw couplings
Website design By BotEap.comThe coupling is a common type of mechanical part that can be widely used in many places. It comprises a clutch having an input connection to the power take-off and an output for connection to the power transmission input of the trailer unit. Like other types of mechanical parts, there are also types of couplings such as flexible coupling. In addition, they also have various species, types and sizes.

It is the flexible shaft coupling that can be plugged in and is also backlash free for small to medium torques. A polyurethane insert serves as a connection and compensation element with spiral-shaped teeth and high Shore hardness. This is inserted snugly, with a slight preload, between two high-precision machined hubs with involute-shaped jaws. Various versions with frictional, backlash-free shaft-hub connection are available as standard, ensuring safe torque transfer, even without keyways.

In addition, consideration must be given to the minimum or maximum possible shaft diameter, allowable temperature range, operating factors, and existing shaft misalignment, particularly radial offset. Basically, the selection can be influenced by the size of the coupling and the hardness of the polyurethane insert.

Website design By BotEap.comLike many other types of couplings, the jaw coupling also has many applications. Potential fields of application for jaw couplings range from demanding drive systems in general machine design to applications in instrumentation and control technology to spindle and axis drives of machine tools.
Website design By BotEap.comThere are many standard types of jaw couplings, such as EWD type and EWE type, etc. In order to choose the most satisfactory product, you need to consider many things. The good choice of products is related to performance, reliability, service life, vibration, noise, power, transmission efficiency, transmission precision, economy and other issues. In addition, it is also related to the quality of the product. All in all, the jaw coupling is also an important kind of mechanical product that can be applied to meet different requirements.
