Szukana fraza: [Abstract = "As a result of this, a 5R model was obtained of a five\-bar mechanism. It was demonstrated that there are 16 cases of the intersection of two universal tori with constant linear dimensions and that they differ with the angles of the mutual positions of rotation axes. A particular case of the five\-bar mechanism presented herein is the well\-known Goldberg mechanism \(Goldberg, 1943\), which was initially formed out of a particular case combination of two Bennett mechanisms \(Bennett, 1903\; Baker, 1979\)."]
