Harmonic Drive HPG Standard Planetary Gearheads
Harmonic Drive HPG Standard Planetary Gearheads
HPG standard-series gearheads combine inline planetary reduction, a cross-roller output bearing and a servo-motor mounting arrangement. The family includes flange and shaft output choices and a backlash-compensating design. HPG standard, HPG-R helical, HPGP high-torque and HPG-RA right-angle products have distinct ratings and geometry; their shared branding does not make them interchangeable.
Review Summary
Consider standard HPG for a supported inline rotary axis where its torque-duty, backlash and motor-interface data meet the machine requirement. Select the exact frame, ratio, output and backlash option. A family peak-torque headline should not replace the separate rated-life, repeated-peak and momentary limits.
