Flexible Couplings are one of the major types of couplings. They find use to connect two shafts, end-to-end in the same line to transmit power that is torque from one shaft to another, thereby causing both to rotate in unison, at the same rpm.

The purpose of a Elastic Coupling is to transmit torque from one piece of rotating equipment to another, while accepting at the same time a small amount of misalignment. Flexible coupling misalignment is expressed, as an order of magnitude, in thousandths of an inch. Actual misalignment, expressed in coupling terms, is angular in nature and expressed in angular units, that is, degrees. How much misalignment is a function of the coupling type and installation. An installation variable is the equipment movement due to the temperature changes taking place in the machines as they go from the non-operating state to operation. Some angular values will be used in the discussion of the various types, but, again, these are for reference only. Each application must be reviewed using the type of coupling selected and the specific design proposed by the vendor.

The plum coupling is composed of two semi-couplings with convex claws and a plum-shaped flexible non-metallic element whose hardness can be adjusted. By embedding the plum-shaped flexible element into the two semi-couplings to realize the connection, it has the characteristics of compensating the relative displacement of the two axes, reducing vibration and buffering, simple structure and easy maintenance without lubrication.

Flexible plum blossom coupling is made up of semi-shaft coupling with the same protruding claw and flexible component.utilizing the plum blossom elastic component put between the protruding claw and two half shaft coupling.in order to realize the connection of two semiaxis devices.

Jaw coupling has compensating by two axle to be relative skew,reducing shaking buffering.smaller diameter simple structure.without lubricating.bearing large capacity,and convenient repair But the semi-shaft coupling needs to move along the axial while changing the elastic component.

Claw coupling is suitable for two with axis,start frequent,positive and negative change,low-speed and medium speed.medium and small powerrotate axle department,requiring working dependability high working position;it is not suitable for the heavily loaded and restricted axial in size.Two axis put in the difficult position after exchange of flexible component.
