An intermediate parallel shaft ‘Z’ is used for gearing together two shafts ‘X’ and ‘Y’ which are co-axial to each other. The gear wheel connecting ‘X’ and ‘Z’ have a module of 2 and those connecting ‘Z’ and ‘Y’ a module of 3. The speed of ‘Y’ is to be about, but less than, 1/12 that of ‘X’. If the two pinions have 24 teeth each, find suitable numbers of teeth for the gears and pinions, the actual velocity ratio and the corresponding distance of shaft ‘Z’ from shaft ‘X’.
