ROBA®-DS (heavy duty)

ROBA®-DS (heavy duty):

  • Adapté aux applications pour charges lou
  • Rigide en torsion
  • Système de construction modulaire flexib
  • Compensation des désalignements d’arbres
  • Sans entretien

ROBA® -DS couplings connect shafts. They transmit torques in a torsionally rigid and backlash-free manner. 

On the ROBA®-DS with conical connection, the disk pack is connected via positive locking with the hubs, the flanges or the sleeves. Externally conical bolts are pulled into conical bores in the attachment parts and the collar bushings of the disk packs by tensioning screws. The conical shape produces forces which widen the collar bushings and the attachment parts radially elastically, thus guaranteeing a backlash-free connection of the disk pack. For this backlash-free, positive locking connection, far lower screw tightening torques are required in comparison to standard frictionally locking connections. This makes installation substantially easier. The disk packs and the sleeves can be installed and de-installed radially without having to move the respective aggregates.
