A gear pump based on harmonic gear drive

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2013
Aimed at solving the problems of radial fluid pressure imbalance, bigger flow ripple and shorter service life that exists in traditional gear pumps, a new type of gear pump based on the principle of harmonic gear drive is put forth, where the function for pumping fluid is achieved by mutual engagement between flexible gear and rigid gear.

Non-Linear Dynamic Modeling and Experiment of Harmonic Gear Drive

Applied Mechanics and Materials, 2014
A non-linear torsional vibration model of harmonic gear drive is proposed in the current study. The model includes clearance, nonlinearity torsional stiffness and nonlinearity damping. The clearance model is developed by introducing the piecewise-linear displacement functions.
