Static Balancing of Mechanical Systems Used in Medical Engineering Field – Continuous Balancing
Abstract:
In medical field are used many categories of mechanical systems, from simple mechanisms to the complex mechatronic systems. Present paper is focused to those mechanical systems that are working in vertical plane by supporting loads or by lifting weights. The targets are both patients and medical workers. Paper is proposing some new devices and mechanisms for supporting the weights that are hanged to the ceiling. These mechanical systems are called too with zero-stiffness because the balancing force does not depend to elongation of elastic system. For all the presented solutions the balancing of the weight forces will be done by using the elastic forces of torsion spiral springs and cylindrical helical springs with straight characteristics. The balancing is made exactly for all positions throughout the work field.
