A coupling can be defined as a mechanical device used to transmit power and permanently connect two rotating shafts. For example, a coupling is used to connect the output shaft of a motor to the input shaft of a hydraulic well pump, or to connect the output shaft of an electric motor to the input shaft of a gearbox in machinery. Disc couplings are very suitable for use in medium and high torque applications that require torsional rigidity.

The advantages of this type of coupling are compatibility with operating conditions with misalignment (axial, angular and lateral), and the lack of the need for lubrication. Lateral misalignment is also known as radial misalignment or parallel offset. Also, these couplings can be used in both spacer-free and spacer-equipped modes.

Disc couplings with spacers can compensate for angular, axial and parallel offset misalignment. While disc couplings without spacers can only compensate for angular and axial misalignment. Therefore, spacer-free couplings cannot be used where there is a parallel offset.

With more than a decade of experience in industrial fields, Tavan Mohar Company has designed and manufactured couplings in various sizes and with diverse applications. Disc couplings designed by Tavan Mohar Company include: two hubs, and a stainless steel disc pack.

In a spacer coupling, the length of the spacer is placed between two disc pack assemblies.

The disc packs and spacers can be moved or installed radially, and there is no need to move the rest of the assembly components.

The coupling system components such as the hub and flange are machined. For this reason, they can be easily used for high-speed applications.
