Harmonic Drive, LLC. offers precision gears, gearheads, servo actuators and motion control systems. Multiple manufacturing facilities in the United States, Japan and Germany maintain the high-quality, precision and reliability standards required by the industry.

Harmonic Drive strain wave gearing is known for zero backlash, high torque, compact size, and excellent positional accuracy. Our motion control products including servo actuators, gearheads, gearing components exhibit these attributes.

Excellent Positional Accuracy and Repeatability - Positional accuracy may be minimized within one arc minute and repeatability within a few seconds.

High Torque Capacity - Since power is transmitted through multiple tooth engagement, the gear offers high output torque capacity equal to drives twice its size and three times its weight.

Single-Stage High Reduction Ratio - With only three elements, the single-stage reduction ratios range from 50:1 to 320:1 with the same weight and mechanical dimensions.

Zero Backlash - Cup-type gear operates with zero backlash between mating teeth because of natural gear preload and radial tooth movement. The only shaft-to-shaft backlash that exists, originates in the input coupling (oldham coupling) and ranges from 2-36 arc-sec depending on unit size and reduction ratio. This coupling can be eliminated if necessary, resulting in zero backlash for the entire drive.

In - Line Configuration - The gearing input and output shafts are concentric, allowing machine designers to dramatically reduce the required packaging space compared to other high ratio, high torque drives.

High Torsional Stiffness - The new "S" tooth profile greatly improves the torsional stiffness of the gear allowing greater precision and higher servo gains.

Efficiencies - Operating efficiencies of up to 90% can be obtained. Ratings are based on actual shaft-to-shaft tests.

Back Driving - Harmonic Drive gear is reversible and can be back driven. If necessary, loads can be held in place by braking the Wave Generator when the servo system is not powered.

Application engineers are available for technical consultation and customer service. Fully equipped facilities provide integration of components as well as prototype assembly.
