Balancing of Stephenson’s Mechanisms

Abstract

This paper deals with the problem of shaking force and shaking moment balancing of high speed planar mechanisms. The design equations and techniques for the complete shaking force and shaking moment balancing of two types of six-bar linkages due to both linear and rotary inertia but without considering external loads are developed. Shaking force is balanced by the method of redistribution of mass and shaking moment by the geared inertia counterweight and planetary-gear-train inertia counter- weight. These geared inertia counter weights are very useful for balancing of multi-bar linkages. The proposed techniques produce better results than that of the previous techniques.
