Harmonic Drive: Hollow Shaft Gear Units (HPF Series)

These gearheads can be easily adapted to any OEM servo motor. Harmonic Drive® gear products offer zero-backlash with gear ratios from 30:1 to 160:1. Precision planetary gearing products are available with gear ratios from 3:1 to 45:1 with backlash maintained below 1 arc-min. High capacity output bearings are utilized for robust and accurate support of loads. Other benefits include flange and shaft output configurations, hollow shaft designs, and sizes ranging from 0.625 inches to over 10 inches in diameter.

Harmonic Gear Principle

Harmonic Drive® gearing utilizes a unique operating principle which is based upon the elastic mechanics of metals. The greatest benefits are the zero-backlash characteristics and the weight and space savings compared to other gears because our gear mechanism consists of only three basic parts. They are the: Wave Generator, Flexspline and Circular Spline.

This simple three element construction combined with the unique operating principle allows extremely high reduction ratio in a very compact and lightweight package. Neither the size nor weight of the gear vary with the reduction ratio. The high performance attributes of this gearing technology including zero backlash, high torque, compact size, excellent positional accuracy and repeatability are all a direct result of the unique operating principle.

HPF Series: Hollow Shaft Gearheads

The HPF Harmonic Planetary® gear unit delivers High-Torque and High-Accuracy with a Hollow Shaft design. The gearhead incorporates continuous backlash compensation that ensures low backlash throughout the life of the gear. An extra-large Cross Roller bearing serves as the output flange and can directly support large loads with exceptionally high moment stiffness. The large coaxial hollow shaft allows cables, shafts, ball screws or lasers to pass directly through the axis of rotation.

  • Available in 2 Frame Sizes

  • Peak Torque: 100Nm to 200Nm

  • Ratio: 11:1

  • Backlash <3 arc-min

  • Extra-large Cross Roller output bearing
