PCT No. PCT/DE92/00954 Sec. 371 Date May 13, 1994 Sec. 102(e) Date May 13, 1994 PCT Filed Nov. 15, 1992 PCT Pub. No. WO93/10336 PCT Pub. Date May 27, 1993.The present invention provides a disassemblable camshaft for internal combustion engines features a cylindrical shaft which in a single operation can be inserted in the bearing bores and cams arranged in between, so that undivided bearings of relatively small diameter can be used. The cams are joined in rotationally fixed fashion to the shaft by pinch-fitting them on the shaft. Transverse screw joints utilizing tensionally stressed clamping screws improve the fixed joint between the cam and both the conic sleeve and shaft. The screw joints are fashioned in a manner such that no additional construction space is needed as compared to conventional camshafts and assembly can be performed with only standard tools.
