  • Assembled shaft element, particularly assembled camshaft for valve-controlled internal combustion engines
    Patent number: 8662043
    Abstract: The present invention relates to an assembled shaft element, in particular an assembled camshaft for valve-controlled internal combustion engines, wherein a hub body having at least one functional part, in particular at least one cam, is held on a shaft by a formfit connection using a splined tooth system in the circumferential direction, wherein the splined tooth system includes shaft splines formed on the shaft and interacting with hub body splines formed in a hub body recess. According to the invention, the at least one hub body (14) is held in addition to the circumferential formfit connection by an interference fit on the shaft (12) implemented by a press fit between a tooth circle of the shaft splines (22) and a root circle of the hub body splines (26). The invention further relates to a method for producing an assembled camshaft for valve-controlled internal combustion engines.
