Malásek, Petr ; Novotný, Lubomír (referee) ; Marek, Jiří (advisor)
This thesis is dealing with determining of technical and economical limits of axis X of portal milling machine driven by gear rack and pinion. And designing drive of axis like this. In chapter overview of the current state of knowledge are researched options of drive systems of linear axis, primarily of using ball screw and couple of pinion and gear rack. Basic parameters of axis X portal milling machines, options of measuring, guiding of axis and electric motors. Then the limit suitability of using pinion and gear rack is determined. In next chapters is designed few variations of arrangements of drives and selected the best one. This arrangement is then designed.
