Abstract: The invention relates to a device for angularly adjusting an internal combustion engine camshaft in relation to a crankshaft and comprises an adjusting bushing connected to the camshaft, with an input sleeve surrounding said bushing, and with an actuator displaceably arranged there between. An input sleeve, the actuator, and the adjusting bushing are each provided with helical gear teeth to translate axial shifting of the actuator into relative rotation between the camshaft and crankshaft. In order to prevent rattling noises in the gear teeth that are caused by changing moments in the drive of the camshaft, the actuator is guided in stop-free fashion. A stop, which is effective between the input sleeve and camshaft, limits the angular adjustment so that the actuator is stressed between the input sleeve and camshaft to avoid backlash during rattling.
