Planet Gear HarmonicPlanetary® Speed Reducer HPG Series Gear Head Type (helical gear)

Features

NEW

  • Wide range of speed ratios
    The addition of a two-level speed reduction type means we now offer reduction ratios from 3 to 50
  • Quieter operation and higher torque capacity achieved by a helical gear (approx. 30% higher compared to conventional designs)
  • Low backlash (standard product 3 arc-min or less, precision product 1 arc-min or less)
  • Accurate rotation with original high accuracy cross roller bearing (high surface runout accuracy)

Integer full speed ratios from low-speed reduction 3 to 50 have been added to new HarmonicPlanetary® HPG Series models with a helical gear.
A helical gear is also used for the thin flexible gear, which achieves high reliability with extremely low backlash degradation.
The characteristics of the helical gear contribute to achieve quieter operation and higher torque capacity (approx. 30% higher compared to conventional designs) and deliver reduction ratios optimal for designing various machines and equipment.
