The harmony of the three basic components of the harmonic drive-the flexible wheel, the stiff wheel, and the wave generator-defines its working concept. The wave generator drives the elastic wavy teeth of the flexible wheel by means of a unique waveform created by the rotation of its elliptical gear, hence producing elastic deformation. The great energy storage capacity of this deformation makes effective energy transmission possible.
Harmonic drive's special functioning mechanism makes it extensively employed in many precision instruments including astronomical telescopes. Its great accuracy and consistent performance guarantee in complicated surroundings the exact functioning and long-term dependability of these equipment.
