A pushrod harmonic institution which is consisted of harmonic planetary and cam mechanism is proposed. As a result, speed-down device of low-speed motor is changed from external installed to interior installed. Design goals of the transmission with small size, light weight and low cost is achieved. Based on the mechanism principle analysis, the theoretical profile equation of the pushrod roller is deduced, then the displacement, velocity and acceleration equation of a random points are got by the analysis method. It is helpful to analyze the change of each motion parameters and the amplitude for the influence of the movement characteristics, at the same time provides evidence for mechanism simulation, kinematics parameters optimization and high-quality manufacturing of the equipment.
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.
