What is an elastomeric coupling?

Elastomeric couplings are essentially a coupling made from a flexible elastic material that transmits torque. This specific type of coupling is designed to allow the elastic to wear out before the actual metal components wear out.

Is a coupling a sleeve?

A Sleeve coupling is a basic type of coupling. This consists of a pipe whose bore is finished to the required tolerance based on the shaft size. Based on the usage of the coupling a keyway is made in the bore in order to transmit the torque by means of the key.

What types of misalignments can an elastomeric shear tire coupling accommodate?

To be considered flexible, a coupling must handle parallel and angular misalignment. Couplings with four-way flexibility accommodate both end float and torsional movement.

Which is related to the sleeve which couples the two shafts comprises two halves bolted together?

a key and sleeve are useful to transmit power from one shaft to another shaft. In this coupling, the muff or sleeve is made into two halves parts of the cast iron and they are joined together by means of mild steel studs or bolts.

What is meaning of elastomeric?

Definition of elastomer : any of various elastic substances resembling rubber polyvinyl elastomers.

What is an elastomeric component?

elastomer, any rubbery material composed of long chainlike molecules, or polymers, that are capable of recovering their original shape after being stretched to great extents—hence the name elastomer, from “elastic polymer.” Under normal conditions the long molecules making up an elastomeric material are irregularly …

What are the three types of misalignment?

The main types of misalignment are angular, radial, and axial displacement.

What is one of the advantages of elastomer couplings over flexible metal couplings?

Elastomeric couplings also have good vibration dampening and shock absorbing qualities and allow for more misalignment than most metallic couplings. The couplings are, however, sensitive to chemicals and high temperatures and are usually not torsionally stiff enough for positive displacement.

What are the three types of couplings?

They can create effective seals between two tubes, and hence, in addition to power transmission, they are used in pressurised fluid systems. Flange couplings are of three major types: Unprotected type flange coupling. Protected type flange coupling.

What are the two types of coupling?

Following are the different types of coupling:

  • Rigid Coupling.
  • Sleeve or muff coupling.
  • Clamp or split-muff or compression coupling, and.
  • Flange coupling.
  • Flexible coupling.
  • Bushed pin-type coupling,
  • Universal coupling.
  • Oldham coupling.
