A rigid open coupling is a mechanical component used to connect two shafts and transmit torque. Its open structure design facilitates installation and operation without the need for axial movement of the shaft. This type of coupling plays a key role in heavy machinery such as crushers, pumps, and ship propulsion systems. It can withstand huge torques and adapt to harsh working conditions. Its rigid characteristics ensure direct transmission of torque, which is crucial for the synchronous operation of precision processing equipment or printing presses. In terms of material selection, the use of materials such as steel or stainless steel improves the durability of the coupling, while surface treatment processes such as quenching and electroplating further enhance its wear resistance. Rigid open couplings combine strong torque transmission capabilities with convenient installation methods, making them a trustworthy component in systems that require high mechanical stability and focus on maintenance efficiency.

What is another name for a rigid coupling?
Rigid couplings, also called muff or sleeve couplingsconsist of cylindrical sleeves, and are the simplest type of coupling. However, they arenot used very often because the shafts of the motor anddriven load must be axially aligned and kept parallelaccurately.
Why use rigid coupling?
Rigid couplings are designed to connect two shafts together so that no relative motion occurs between them. Rigid couplings are suitable when precise alignment of two shafts is required. lf significant radialor axial misalignment occurs, high stresses may result, which can lead to early failure.
What is the most common type of rigid coupling?
Sleeve Couplings also called Muff Couplings or straight tooth couplings are the most common type of rigid coupling and consists of a solid cylindrical sleeve that connects two shafts. They are easy to install and require no special tools.
