PLANETARY GEAR

摘要

A machine tool transmission, in particular a spindle transmission, with which the force and/or the torque transfer from an output shaft ( 3 ) of a transmission ( 1 ) takes place directly on a spindle ( 15 ). The spindle ( 15 ) is placed co-axially over the output shaft ( 3 ). An integration of a sealed rotary feed-through is proposed to serve as a transfer device for the flow of cooling fluids, oil or air between the transmission output shaft and the spindle ( 15 ).
