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.
Abstract translation: 本发明涉及一种用于相对于曲轴角度地调节内燃机凸轮轴的装置,包括连接到凸轮轴的调节衬套,围绕所述衬套的输入套筒以及可移动地布置在其间的致动器。 输入套筒,致动器和调节衬套均设有斜齿轮齿,用于将致动器的轴向移动转换成凸轮轴和曲轴之间的相对旋转。 为了防止由凸轮轴的驱动中的转矩引起的齿轮齿中的晃动噪声,致动器以无停止的方式被引导。 在输入套筒和凸轮轴之间有效的止动器限制了角度调节,使得致动器在输入套筒和凸轮轴之间受到应力,以避免在晃动期间产生间隙。
