Abstract:Kinematic error is an important indicator for evaluating the performance of harmonic drive gears. Previous methods for calculating the kinematic error only considered a single meshing tooth, the effect of other meshing teeth was compensated by the error homogenization coefficient. Because of the complex contact state of harmonic drive gears, the results of these methods are always inconsistent with experimental results. This paper proposes a mathematical model considering all meshing teeth to predict the pure … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
