On the Kinematic Error in Harmonic Drive Gears
Journal of Mechanical Design, 1998 Harmonic drive gears are widely used in space applications, robotics, and precision positioning systems because of their attractive attributes including near-zero backlash, high speed reduction ratio, compact size, and small weight. On the other hand, they possess an inherent periodic positioning error known as kinematic error responsible for ...

Study on Gear Contact Stiffness and Backlash of Harmonic Drive Based on Fractal Theory [PDF]
Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2021 Abstract Contact stiffness and backlash model of harmonic reducer is related to robot’s positioning accuracy and vibration characteristics. Harmonic reducer tooth pair height is typically less than 1 mm. Thus, backlash and contact stiffness measurement and modeling are relatively complex.
