Product information

Belt management will be facing major challenges in a variety of applications. Optimized combustion processes, higher torques and power outputs, the reduction of centrifugal masses, increasingly stringent emissions standards - all this leads to increased rotational vibrations. These vibrations are passed on to the auxiliary units through the drive belts. The consequences hereof are noise emissions, wear and fastening problems as well as increased energy consumption.

This is where Kendrion's LDDlite torsional vibration damper of the LINNIG brand provides a convincing solution by significantly reducing generator vibrations. In this, the torsional vibration damper ensures double damping based on the following two features:

  • Permanent magnets achieve a progressive, smooth damping function while transferring low to medium-range torque.
  • Special rubber dampers are used as the stop for full power transfer of maximum torques.

The decisive unique characteristic is a result of the properties of a permanent-magnet system: Contact-free power or load transmission means wear-free operation, so that Kendrion's system will not be outdone in terms of service life.

The characteristic curve can be flexibly adapted to individual customer requirements, depending on the number and arrangement of the magnets. Even when retrofitting existing fleets, Kendrion torsional vibration dampers of the LINNIG brand provide a convincing and practical solution, as the installation is very simple: The present pulley package can be replaced as a complete unit – with the immediate result of desired quiet-running.
