摘要： A multi-spindle automatic lathe comprises several workpiece spindles driven by separate drive motors through gear units arranged outside the spindle circle. The motors are disposed behind the spindle drum in positions to which the indexing of the spindle drum brings the gear units, so that the gear units can then be coupled to the motors through cone friction clutches comprising parts mounted on the gear units to be displaceable along the axes of the drive output shafts and engage axially non-displaceable parts of the clutches transmitting the drive from said shafts. In the event of axial misalignment each axially non-displaceable clutch part is so connected to its drive output shaft through a cardan shaft that said clutch part can move radially and compensate for the misalignment.
