摘要： A camshaft arrangement includes an adjustable camshaft and an adjuster for adjusting the camshaft. The adjustable camshaft includes an outer shaft and an inner shaft arranged rotatably in the outer shaft. The adjuster includes a stator connected with the outer shaft in a rotationally fixed manner, and a rotor connected in a rotationally fixed inner with the inner shaft via an axially inserted coupling. A bush is connected with the rotor in a rotationally fixed manner and has at least one channel for supplying a lubricant. The bush has on a face side that axially faces the inner shaft a form that together with a counter-form on the inner shaft provides the axially inserted coupling.
