A novel approach to obtaining localized bearing contact of spiroid gear drives has been developed. The localized contact is achieved by modifying the pinion tooth surface. With this approach, only the pinion cutter’s geometrical angles and mounting position need to be adjusted, and, hence, it is simpler and more economical than other methods. In this paper the following are presented: overview of the approach, equations for modified spiroid gear tooth geometry, and computer simulation results. The results confirm that the proposed modification of the tooth geometry pennits localized bearing contact.
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.
