Abstract
An assembled camshaft (11) wherein at least one oil distributing sleeve (14, 26) for a camshaft setting device (15) is secured in a force-locking way to a plastically expanded portion of a shaft tube (12), wherein the oil distributing sleeve (14) includes a seat face (31) centered on the axis A of the shaft tube (12) and/or a radial contact face (32) for the camshaft setting device (15), which radial contact face (32) is aligned in a normal way relative to the axis A of the shaft tube (12).
Claims15
An assembled camshaft (11), comprising:
- a shaft tube (12) including a plastically expanded portion;
- a camshaft setting device (15) secured to the shaft tube (12);
- at least one oil distributing sleeve (14, 26) for the camshaft setting device (15) and secured to the plastically expanded portion of the shaft tube (12), wherein the oil distributing sleeve (14, 26) includes one of a seat face (31) centered on the longitudinal axis (A) of the shaft tube (12) and a radial contact face (32), for the camshaft setting device (15), which radial contact face (32) is aligned axis-normal relative to the longitudinal axis (A) of the shaft tube (12).
A method of producing an assembled camshaft (11), comprising the following steps:
- providing a camshaft setting device (15) on a shaft tube (12) such that the camshaft setting device is centered relative to the longitudinal axis (A) of the shaft tube;
- securing at least one oil distributing sleeve (14, 26) for the cam-shaft setting device (15) to a plastically expanded portion of the shaft tube (12);
- machining at least one of a cylindrical seat face (31) and a contact face (34), for the camshaft setting device, which extends in a normal direction relative to the longitudinal axis (A) of the shaft tube (12) on said oil distributing sleeve (14, 26);
- and
- securing the camshaft setting device (15) into contact with the at least one oil distributing sleeve (14, 26) on the shaft tube (12).
