A gear pump based on harmonic gear drive
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2013Aimed 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.

Torsional rigidity of harmonic gear drives
Russian Engineering Research, 2016A model is proposed for harmonic gear drives. The model takes into account that harmonic engagement involves multiple pairs and multiple zones and also takes account of the manufacturing and assembly errors, the deformation of the drive components, and the adjustment of the gaps in the engagement under load.

2009 IEEE International Electric Machines and Drives Conference, 2009
The harmonic gear is among the more interesting mechanical devices for amplifying torque. This gear has zero backlash with high gear ratios. The number of teeth on the rotor is typically two less than that on the stator. An electromechanical motor equivalent to this device is discussed and analyzed.

On a Gearing Problem in Conventional Harmonic Drives With Involute Toothed Gear Set
Volume 8: 11th International Power Transmission and Gearing Conference; 13th International Conference on Advanced Vehicle and Tire Technologies, 2011Circular pitches of flex spline teeth of a ‘Strain Wave Gearing’, also known as a ‘Harmonic Drive’, are deformed when the Strain Wave Generating Cam is inserted into the flex spline cup. In the present work the deformed pitch distances considering that flex spline teeth remain rigid while the rim deforms, are estimated.

Kinematics and Enumeration of Combined Harmonic Drive Gearing
Journal of Mechanical Design, 2015The combined harmonic drive (HD) gearing is a class of differential gears composed of traditional and HD gears. In this paper, the kinematic analysis and enumeration of these less known gear devices are discussed. In particular, a new graph-based method of kinematic analysis has been developed.

The Effects of Harmonic Drive Gears on Robot Dynamics
17th Design Automation Conference: Volume 2 — Computer-Aided Design, Mechanical Systems Simulation, and Analysis, Mechanisms, and Robotics, 1991Abstract Mathematical models of the harmonic drive have been developed, and their effects on manipulator dynamics have been examined. The harmonic drive is modelled as a flexible gear with a high gear reduction ratio. The recursive Newton-Euler dynamic formulation is applied to deriving the system equations of motion that include the ...

Planetary-Gear-Type Second-Harmonic Balancers
Journal of Mechanisms, Transmissions, and Automation in Design, 1987This paper describes several mechanical balancers, based on the planetary gear trains known as the hypotrochoid and epitrochoid trains, for reducing or eliminating second-order out-of-balance in mechanical systems. It is shown that by proper arrangement of the planetary gear trains, a balancer can be obtained for the elimination of second-order shaking

The Analysis And Design Of Harmonic Gear Drives
Proceedings of the 1988 IEEE International Conference on Systems, Man, and Cybernetics, 2005Harmonic gear drive, a compact mechanical device producing high mechanical advantage and speed reduction, has been used to accurately position the arms and wrists of robots. This device, operating on the principle of nonrigid body mechanicsr has been found to have positioning errors. Such errors, inherent in the drive, adversely affect the performance.
