A fluid coupling is a hydrodynamic device that transmits rotational power from an engine to machinery without using a mechanical connection. It uses a liquid, typically oil, to transfer torque between an input impeller and an output turbine, providing smooth, gradual acceleration and overload protection.

JAW couplings are a type of flexible coupling known for their high torque capacity and ability to accommodate misalignment. This brief introduction highlights their key distinctions from other common coupling types, such as gear, grid, and elastomeric couplings, focusing on design, performance, and typical applications.

Introduction to calculating the service factor for chain couplings.

A rigid coupling is a mechanical device used to connect two shafts together, transmitting torque while maintaining precise alignment and preventing relative movement between them.

This introduction briefly explains the role of MH couplings in reducing vibrations and improving overall stability within a drive system.

This article explores typical failure modes of FCL couplings with PIN designs, covering causes and preventive measures.
