  • Type:

    hydrodynamic, gear

  • Rotational speed:

    Min.: 0 rpm (0 rad.min-1)

    Max.: 20,000 rpm (125,663.71 rad.min-1)


The core components of the geared variable speed coupling are a hydrodynamic variable speed coupling combined with a mechanical gear stage. The gear stage is designed for the initial increase or decrease of the input driver speed. The variable speed coupling then varies the speed of the driven machine within the required range.

Variable speed drives using a Voith geared variable speed coupling are compact, efficient and offer unbeatable reliability. The reliability of the couplings is 99.97%. The range of application includes powers up to 30 MW and output speeds up to 20,000 rpm. The standard motor and the geared variable speed coupling form a strong pairing in the thermal power plants and in oil and gas industry applications.
