A Rubber coupling is an elastic coupling and consists of a flexible element—the tyre—and two coupling halves, also referred to as the hub or flange.As tyre couplings are flexible, they can compensate for significant angle errors and have a vibration and impact-damping effect.
Rubber couplings are used extensively in many industrial applications, especially with engines. Mainly used for their torsionally soft properties and damping effect on troublesome vibrations.
Rubber coupling device is used to reduce vibration in engines and also reduces the torque oscillation.These couplings are used to transmit the torque in between two hubs. The rubber torsional coupling is used in universal joints, shafts and flywheels.
