Planetary Gearheads Add Helical Gearing, Low Reduction Ratios

Harmonic Drive (Peabody, MA) has added HPG gearheads with helical gearing and low reduction ratios to its current planetary gearhead lineup. The new models, HPG-R, feature:

• Low-speed ratios from 3:1 through 10:1, including all integer ratios in between.
• Helical gearing for improved noise reduction and higher torque capacity.
• Suitable for a variety of machinery and equipment designs.
• A special design that allows a preload of the gear (on the order of microns) and enables it to slightly deform elastically thus maintaining low backlash without need for adjustment.
• Preload that also compensates for interference between meshing parts.
• A Quick Connect coupling for mounting to any servo motor.
• Available with flange output, shaft output without key and shaft output with key and center tapped hole.
