A Torsional Coupling is used to transmit torque while accommodating angular misalignments and dampening torsional vibrations between the rotating elements. It consists of an input and output hub, an input hub connected to the engine's output shaft, and the output hub linked to the air compressor. These hubs are connected by an intermediate element, often it is a flexible material and allows it to absorb torsional vibrations generated by the engine.Attributes:• Reduce excessive torsional vibrations, leading to fatigue failure• Provided with a maximum speed limit of 3000 rpm Applications:A Torsional Coupling ensures the transfer of torque between two rotating shafts while compensating for misalignment, vibration, and shock loads. It helps to protect the drivetrain components and ensures a smooth power transmission unit.
