Harmonic Drive LLC, a leader in high precision motion control adds Harmonic Planetary HPG gearheads with helical gearing and low reduction ratios to its current planetary gearhead lineup. Harmonic Gearhead products are available with quick lead times. 
The new models, 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. Ideal for a variety of machinery and equipment designs, these new models enhance the already successful HPG series.
A special design of the HPG internal gear allows a preload of the gear and enables it to slightly deform elastically thus maintaining low backlash for the life of the gearhead, without any need for adjustment. This preload not only minimizes backlash but also compensates for interference between meshing parts. The result is low backlash for the life of the gear, without any backlash creep.
Like all Harmonic Planetary gearheads, the HPG-Helical gears feature Quick Connect coupling for easy mounting to any servo motor. They are also available with flange output, shaft output without key and shaft output with key and center tapped hole.
