Types of Couplings

by Smriti G. Technical Consultant

Types of Couplings fall into two fundamental classifications: Material Flexing Couplings and Mechanical Flexing Couplings. The material flexible types acquire their flexibility from extending or compacting a versatile material, for example, elastic, or from the flexing of flimsy metallic circles or framework.

Material flexing couplings don’t require lubrication, except for grid couplings.

The mechanical flexing couplings acknowledge misalignment from rocking, rolling, or sliding of metal surfaces. All metal mechanical flexing couplings require lubrication.

Here are the types of couplings.

Jaw Couplings:

The jaw couplings are types of couplings that transmit torque through the pressure of an elastomeric insect addition put between two intermeshing jaws.

•Flex component is ordinarily made of NBR, polyurethane, Hytrel or Bronze

•Accommodates misalignment

•Transmits torque

•Used for torsional hosing (vibration)

•Low torque, broadly useful applications

Sleeve Couplings:

The sleeve couplings are types of couplings that transmit low to medium torque between associated hardware in shear through an elastomeric embed with male splines that mate with female hub splines.

The supplement material is ordinarily EPDM, Neoprene, or Hytrel and the addition can be a couple of piece designs.

•Moderate misalignment

•Torsional hosing (vibration)

•End drift with slight hub freedom

•Low to medium torque, universally useful applications
