... of such a cam mechanism can serve as the grooved types. Since the follower has three rollers that can simultaneously contact the cam at any instant, it can be positively driven along the guided groove of the cam contour. The contact forces and contact stresses of such a cam mechanism are analyzed to illustrate...

...Chiu-Fan Hsieh Gerotor performance is influenced by sealing properties, area efficiency, contact stress, and outlet pressure. This paper uses the hypotrochoidal curve to generate the gerotor profile, and adopts the curvature difference method to assess the sealing property and predict the stress...

... of pumps have demanded to maximize efficiency and to reduce manufacturing costs by improving its two main performance indexes: volumetric characteristics and teeth contact stress. The existing methodologies and software fail to thoroughly address the design by taking into account both performance indexes...
