Elastic coupling motor fitting

In 2006, Varvel introduced a valuable and upgrading feature to the 'flexibility

evolution': the strategic road map of the company's development in years to come.

The usual key-coupling between motor and gearbox was replaced by a customized type "G" elastic coupling without any increase in the geared motor dimensions.

The advantages of elastic coupling usage are:

  • inventory reduction, just one reducer stocked for each ratio regardless input shafts;
  • flexibility and stock-rotation increase;
  • fretting corrosion elimination;
  • zero backlash in motor/reducer fit;
  • reduced heat transmission via motor shaft;
  • high motor vibration damping.

The elastic coupling "G" is now available on:

  • Worm speed reducers series RS from size 28 to 110;
  • Worm speed reducers series RT, all sizes;
  • Helical speed reducers series RD, all sizes;
  • Shaft mounted parallel reducers series RN, all sizes;
  • Bevel/helical reducers series RO e RV, all sizes.
