Abstract
A machine tool gear mechanism (1) such as a spindle gear mechanism, transmits torque from an output shaft (3) of the gear mechanism directly to a spindle (6). The mechanism includes a rotary passage (14) as a device for delivering coolants, emulsions, oils or air between the output shaft (3) or the motor and the spindle (6). The rotary passage (14) is integrated in the spindle (6).
