Properties

MATERIAL

  • Coupling from high strength steel

DESIGN

  • Hubs with keyway mounting or high precision cylindrical bore for interference fitting. Optional DIN 916 set screw for locking down onto shaft key.

 

 

  • Properties of Crowned Gear Coupling model BZ1:
    • high power density

    • very low backlash

    • economically priced

    • low maintenance due to special crowned tooth design
  • Function of the Gear Coupling:
    • the precise integration of the coupling hub and intermediate flange allow for low backlash and highly rigid torque transmission, while compensating for lateral, axial, and angular shaft misalignment.
    • the crowned geometry of the gearing allows for a long life, even without the presence of misalignment.
