Design Overview

Description/Basics

A shaft coupling, also called a compensating coupling, is generally used for the transmission of torque for mechanical engineering. Flexible shaft couplings (non-rigid) can compensate for lateral, axial and angular offsets (misalignment). Therefore, these are common connecting elements between motors and axles/shafts or even ball screws.

There are various types of designs, such as the jaw couplings, disc couplings (servo couplings), slit couplings, bellow couplings, Oldham couplings and many others, which are selected depending on the type of misalignment. You can determine which design is the right one for transmission in your application with the Coupling Selection Method available as a PDF.

When the shaft coupling is professionally installed, the transmission of rotational forces should be slip-free. To do this, the appropriate shaft coupling must be selected depending on the application. Here, it is important to observe the degree of misalignment, the maximum speed of rotation and the permissible torque of the compensation coupling and not to exceed these values during operation. If several misalignments occur at the same time, it is recommended to reduce the maximum value of the specified misalignment by approximately half.

The most commonly used elastomer coupling is the jaw coupling, which consists of a plastic buffer with damping properties. As a result, shocks and vibrations in a drive system can be damped, which protects adjacent components in the transmission of force. Our product range offers you alternative materials for the elastomers. These include among others aluminum bronze and carbon fibre-reinforced plastic.

The different shaft connections on the compensation couplings allow various connection variants for assembly. For this purpose, hub clamping, half shell clamping, slot clamping, threaded pin clamping, chip sleeve and keyways are available.
If a keyway is selected for a MISUMI shaft coupling, it is recommended obtaining the MISUMI machine key, as it is best to combine these.

A shaft coupling can be used for precise positioning. These are often combined together with slide screws or ball screws. A disc clutch (servo coupling) is suitable for this application, since it has a high torsional rigidity.

In addition to the standardized diameter of the shaft bore, MISUMI offers the option LDC and RDC, which allows the drill diameter to be adjusted to the shaft end in 0.1 mm increments.
