A study on stress and vibration analysis of a steel and hybrid flexspline for harmonic drive

摘要

The conventional speed reducer uses the concept of rigid bodies, but the harmonic drive is operated by the elastic theory. As for this, harmonic drive shows different characteristics in operation principles and analysis compared to the conventional ones. Flexspline with components of harmonic drive can generate repeated vibration by the wave generator. Thus flexspline should have a Good vibration characteristic. In this paper, a study on stress, deformation and related vibration characteristics using the finite Element method tool has been carried out on the flexspline as a part of speed reducer.
