Patent number: 8881701Abstract: An adjusting device for adjusting a camshaft relative to a drive sprocket, which drives the camshaft coaxially. The adjusting device includes an actuating gear which acts between the drive sprocket and the camshaft and is driven via an electric motor to adjust the camshaft. The actuating gear has internally- and externally-toothed gearwheels in engagement with each other, in which the internally toothed gearwheel is rotated about a central axis of the adjusting device. The externally toothed gearwheel is arranged eccentrically with respect to the central axis and is driven to perform a circular motion about the central axis. The externally toothed gearwheel is supported eccentrically on at least two eccentric shafts, each eccentric shaft being driven to perform a rotary motion about a respective eccentric axis. The eccentric axes are arranged eccentrically with respect to the central axis and can be rotated about the central axis.Type: GrantFiled: July 6, 2011Date of Patent: November 11, 2014Assignee: MAGNA Powertrain AG & Co KGInventor: Michael Schober
