Shaft Mount Harmonic Differential Gearboxes

Simplifies Installation for New and Retro Fit 3608 Phasing Applications
Our Conic 1:1 shaft mount harmonic differentials offer and excellent option for 3608 phasing, especially when mounting into tight gearing trains where space is limited. We offer standard units, but can easily modify our mounting dimensions to help you facilitate easy installation. The gearbox incorporates two precision harmonic gearing that allow for a 1:1 input/output ratio when the zero trim shaft is held at zero speed. Ideal applications are printing and finishing registration applications.

Models:
20, 25, 32, 40
  • High-speed capability (Over 2500 rpm).
  • Low heat generation. Due to the efficiency inherent in the harmonic gearing, Conic gearboxes run significantly cooler than planetary boxes.
  • Excellent positional accuracy
  • Easy to Install
  • Allows 360° continuous phasing
  • Low backlash
  • U.S. made and stock
  • Alloy Shafts

 

APPLICATIONS:

  • Inline and CI Printing Press Registration
  • Packaging Machines
  • Rotary Cutters / Dies / Gluers / Perforators
