Abstract

A multi-station turret head for machine tools, in particular drilling machines, which has a built in speed change operated automatically as the turret indexes. A gear (50) on the power input shaft (35) drives another (47) on a hollow layshaft (44) which forms part of a gear train (51, 54, 55, 56) operating the output shaft (38). The required speed is selected by a cam rod (68) inside the hollow shaft and moving steel balls (69) to lock selected gears onto the shaft. The speeds required are predetermined and brought into action when the turret indexes by a cam finger (90) raising or lowering the cam rod operating mechanism (66, 67, 91, 92).
