Due to the climate change, changing legislation and increased demands on energy efficiency, the industry is constantly looking for ways to minimize costs. Not only in the packaging industry, but also in the fields of handling and forming technology, non-uniformly translating mechanisms are used to generate certain motions. For several decades now, there have been attempts to operate such mechanisms in a more energy-efficient manner, with so-called eigenmotion being a promising approach. Practical implementation in industry has become possible with the development of servomotors, as they can reproduce the eigenmotion with high precision. The combination of non-uniformly translating mechanisms and a variable drive speed has been the subject of research ever since. The variation of the input speed of a mechanism results in a changed output speed. This article presents the development and the validation of a design method for energy-efficient cam mechanisms while maintaining the exact motion specification.
