Torsional rigidity of harmonic gear drives

Russian Engineering Research, 2016
A 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.

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, 2011
Circular 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.

Drives with harmonic gears for servo systems

Russian Engineering Research, 2016
Various drives with harmonic gear systems and generators of internal and external deformation waves are considered. A method of designing harmonic gear systems on the basis of dialog-based interactive software is outlined. A systems approach to the design of electromechanical servo-system drives improves the design quality and reduces the design time.

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, 1991
Abstract 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 ...

The Analysis And Design Of Harmonic Gear Drives

Proceedings of the 1988 IEEE International Conference on Systems, Man, and Cybernetics, 2005
Harmonic 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.

Kinematics and Enumeration of Combined Harmonic Drive Gearing

Journal of Mechanical Design, 2015
The 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.

Development of magnetic harmonic gear with stackable structure

International Journal of Applied Electromagnetics and Mechanics, 2016
A new type magnetic harmonic gear is proposed. The new magnetic gear has the stackable structure and is assembled easily. The proposed magnetic gear has stacked ring magnets and thin iron plates for the inner and outer rotors. And the two types of the inner and the outer rotors are compared.

Planetary-Gear-Type Second-Harmonic Balancers

Journal of Mechanisms, Transmissions, and Automation in Design, 1987
This 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
