The assembling of machine tool’s change gear quadrants based on modernized sets of gears

A method of assembling the twin-paired change gear quadrant with variable center distance that used on different metalworking machine tools is proposed. The possibility to increase the quality and reducing time of gears adjustment is proved — increase number of gear ratios provided by the modernized set of change gears while the number of change gears in set remains constant. Sets are created based on software tool executing the adjustment of twin-paired change gear quadrants regarding the primary kinematic and design constraints of a machine. The analytical methods and methods of computer modeling are used.
