Harmonic Planetary Gearhead

Harmonic Planetary® HPG gearheads with helical gearing and low reduction ratios are available with quick delivery. 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 (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. 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.

• Ratios: 3,4,5,6,7,8,9 and 10:1
• High Efficiency
• Backlash <3 arc-min (<1arc-min available as an option)
• Repeatability ±20 arc-sec
• High load capacity Cross Roller output bearing
• Quick Connect® coupling for easy mounting of any motor
• Available with flange output, output shaft without key or shaft with key and center tapped hole

Harmonic Drive LLC has a dedicated website for its Harmonic Planetary® and Harmonic Drive® Quick Connect® gearheads (HPN, HPG, HPGP, CSF-GH, CSG-GH, HPF and HPG-U1).  The website offers users a quick and easy way to choose the best Harmonic Drive LLC product for their application. Developed with the design engineer in mind, the website features a robust product selector tool, PDF and DXF CAD drawings, as well as downloadable 3-D solid models. The Product Selector Tool enables the design engineer to quickly filter through Harmonic Drive product specifications to find the right gearhead to connect to their servomotor. 

Known for its expert engineering and manufacturing, Harmonic Drive LLC products are relied upon every day throughout the motion control industry.
