Investigation on Inertia Force Balancing and Torque Compensation of Slider-Crank Mechanisms

Abstract

This paper proposes a new design concept, which allows the simultaneous inertia force balancing and input torque compensation in slider-crank mechanisms. In the previous study, the inertia forces have been cancelled via a cam mechanism carrying a counterweight. Then, the spring designed for maintaining contact in this balancing cam mechanism has been used for torque compensation. Therefore, the spring has been jointed with a second cam mounted on the input crank. Thus, a complete balancing has been achieved. The present study proposes to minimize the shaking force and the input torque by a single cam. The proposed design concept allows one to use only one cam for solving the both mentioned problems. The suggested solution is illustrated by CAD simulations, which show its efficiency.
