LB Series shaft Metal quick Plate Flexible Coupling

A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. Couplings do not normally allow disconnection of shafts during operation, however there are torque limiting couplings which can slip or disconnect when some torque limit is exceeded.

The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. By careful selection, installation and maintenance of couplings, substantial savings can be made in reduced maintenance costs and downtime. 

In a more general context, a coupling can also be a mechanical device that serves to connect the ends of adjacent parts or objects.

Use and characteristics
High torque rigidity and high sensitivity.
Zero rotation gap.
Clockwise and counterclockwise rotation characteristics are exactly the same.
Stainless steel diaphragm compensates for angular and axial deviations.

Applications 
1. Widely used in various mechanical and hydraulic fields 
2. Small dimension, low weight, high transmitted torque 
3. Elastomers made of polyurethane with shore hardness between 80-98 
4. Compensating the axial relative drift, buffer and vibration reduction 
5. Material: cast iron, steel and aluminum alloy
