Gear Principle Principle of Operation The gear was originally developed for space applications to provide reliable performance under harsh conditions. Wave Generator Circular Spline The Wave Generator is a thin raced ball bearing fitted onto an elliptical plug serving as a high efficiency torque converter. A solid steel ring with internal teeth. The Flexspline is slightly smaller in diameter than the Circular Spline resulting in it having two fewer teeth on its outer circumference. It is held in an elliptical shape by the Wave Generator and its teeth engage with the teeth on the Circular...

Hollow Shaft Applications Slow speed output High Speed Input Gears from Harmonic Drive® with large hollow bore Central hollow shaft One of the major advantages of the unique priciple is the optional Hollow Shaft. Depending on the requirements of the application we are able to produce gears with large hollow shafts. This hollow shaft affords the designer a chance to optimize the use of the space available as it can be used to pass services such as: fluids, electric cables, shafts, supply lines and spindles
