Abstract:
PCT No. PCT/EP97/02752 Sec. 371 Date Jul. 28, 1998 Sec. 102(e) Date Jul. 28, 1999 PCT Filed May 28, 1997 PCT Pub. No. WO97/49511 PCT Pub. Date Dec. 31, 1997In order to fasten parts, such as cams, gear wheels, and discs, in a torsionally resistant manner on a hollow shaft, it is proposed to expand the shaft by pulling an expanding drift through the shaft after threading on the parts, which are provided with slight mating play, and consequently to establish at least frictional engagement between the shaft and the parts. A particularly secure connection can then be achieved when the bore of the parts is provided with a profiling into which the material of the shaft displaced by the expanding drift is pressed. Expansion of the shaft may be performed in stages by using an expanding drift having a staged increase in its effective diameter or successively using a plurality of expanding drifts of respectively larger effective diameter.
