NDE Clarke Pitchline Ltd has many years of experience in supplying Highly Flexible Coupling solutions and has built up a unique expertise in their design, selection and engineering.

This means we can offer all the advantages of highly flexible couplings with all the vital technical support and assistance our customers need.We have solved complex problems for a wide range of applications such as static test rigs, mobile plant and marine drive systems, where our Highly Flexible Couplings have delivered improved performance.

 

Features and Benefits

  • Designed to eliminate torsional vibration problems.
  • Designed to be used in conjunction with universal drive shafts.
  • Designed to mount directly onto flywheel of engine.
  • Offered in a variety of torsional stiffness’s.
  • Emergency operation device enables the coupling to continue to operate even when the rubber element fails.

 

Torsional Vibration Problems

Highly Flexible Couplings are introduced into drivelines where resonance or torsional vibration maybe a problem. This problem often occurs when two dissimilar inertias need to be connected together using a relatively flexible connecting shaft or element. When these conditions occur and the prime mover is an internal combustion engine there is a very strong likelihood that resonance will occur somewhere in the operating speed range.

 

Torsional Vibration Analysis

 

Resonance can be very harmful to driveline systems with peak torque in excess of 5 times nominal torque being experienced by the driveline elements which can lead to premature failure.

The introduction of a highly flexible coupling can ensure that any resonance will occur outside the normal operating speed range (normally above) thereby eliminating the possibility of these harmful peak torques being experienced.

A wide range of designs are available to suit flywheel to cardanshafts, shafts to shafts and flange to cardanshafts. The flexible elements can be supplied with different degrees of shore hardness which means we can optimise the coupling precisely to meet the system requirements.

 

Flexset Rubber Block Coupling

The robust, and reliable nature of the Flexset rubber block couplings makes them great couplings for a wide range of applications. Applications include pump sets, generator sets, wind energy, compressors, metal works, pulp and paper industry and many more general purpose industrial applications. Contact us now to discuss any enquiries you have about the Flexset rubber block coupling.

 

Jaw Type Coupling

Jaw type couplings use two hubs and an elastomer element to transmit torque. They are fail-safe because if the elastomer element fails, the hubs can still drive metal to metal. They are also maintenance free as they do not require lubrication. Contact us now to discuss any enquiries you have about the Jaw Type Coupling.

 

Tyre Coupling

Tyre couplings tolerate large amounts of axial, radial, angular and torsional misalignments and aborbs vibration from the transmission to the machines to which they are coupled. Contact us now to discuss any enquiries you have regarding tyre couplings.

 

Flywheel Mounted Couplings

Flywheel mounted couplings are used for a variety of applications. Applications generally involve off-road construction equipment such as aerial lifts, excavators, skid steer loaders and a variety of other mobile hydraulic applications. Mobile machines mainly use internal combustion engines as a drive. The two units are connected via a flywheel coupling to transmit the power reliably to ensure that the machine can perform without failure. Contact us now to discuss any enquiries you have regarding flywheel mounted couplings.
