Zero-Free-Length Elastic Systems for Static Balancing

The static balancing of the weight forces is necessary to any mechanical system which is not working in horizontal plane. The effect is the decreasing of the acting power. From practical point of view two main passive ways of static balancing could be taken into consideration: by mass redistribution of components or/and by adding counterweights, and by elastic forces of the springs or of the gases. The first solution is not always possible due to the dimensions of mechanical systems and due to increasing of the dynamic stresses of components. Second solution is more and more used to various mechanical systems. The complexity of balancing systems with springs comes from the need of using zero-free-length springs. Instead of using complex balancing systems with real springs, some zero-free-length elastic systems are proposed. Present paper is continuing former papers of authors and is presenting some new constructive solutions of zero-free-length elastic systems. Finally an example is solved.
