Harmonic Drive adds Planetary HPG gearheads

Oct. 7, 2016 – Harmonic Drive adds Harmonic Planetary HPG gearheads with helical gearing and low reduction ratios to its current planetary gearhead lineup.

The new model, HPG-R, add low-speed ratios from 3:1 through 10:1 including all integer ratios in between. HPG-R employs helical gearing for improved noise reduction and higher torque capacity, says Harmonic Drive, adding that the gearheads are “ideal” for a variety of machinery and equipment designs. The design of the HPG internal gear allows a preload of the gear (on the order of microns) and enables it to “slightly deform elastically thus maintaining low backlash for the life of the gearhead, without any need for adjustment,” it says. This preload not only minimizes backlash but also compensates for interference between meshing parts, it notes. The HPG-Helical gears also feature Quick Connect coupling, which boasts “easy mounting” to any servo motor.
