Gear unit for valve gear, has freewheel unit tapping oscillation circular motion and converting oscillation circular motion into drive circular motion, and toothed gear units displaceable around phase angle

摘要

The gear unit has an oscillation unit (1a) converting uniform drive circular motion into oscillation circular motion. A freewheel unit (2a) taps the oscillation circular motion and convert the oscillation circular motion into the drive circular motion. Drive units (4a, 5a) are connected with each other in form fit manner for an operating mode. Toothed gear units (6a, 11a) are displaceable around a phase angle. A gear wheel (10a) of the gear unit (6a) and a gear wheel (12a) of the gear unit (11a) are connected with each other in rotational fixed manner.
