In this paper, structure and working principles of oscillating-teeth end-face harmonic gear, as well as its types and classification are investigated, based on statement on structure and development of oscillating drive and harmonic drive.
According to achievements and shortages that have achieved on study of harmonic drive at the present time, by applying elastic theory, nonlinear FEM and the techniques of CAD/CAE, a 3-D model of flexible wheel is established. The model is analyzed by finite element contact method in order to gain stress and displacement of flexible wheel.
Based on AutoCAD platform, the principle of expert system and CAD techniques are adopted to develop the function module of harmonic gear transmission CAD system with ARX and object-oriented techniques.
An external harmonic drive signal is used for stimulating chaos in a system with time delay, in which the parameters admit only rigid excitation of oscillations and a single impact produces only regular motions.
As an efficient actuator, a high-power AC servo motor and a backlash-free harmonic drive reduction gear were utilized.
Disturbance-observer-based adaptive feedforward cancellation of torque ripples in harmonic drive systems
This paper proposes a scheme for controlling the output torque of a harmonic drive actuator equipped with a torque sensor.
This work is directed towards improving the performance of flexible jointrobots equipped with harmonic drive (HD) as gear train mechanism.
