    The invention relates to the field of engineering, in particular to a drive shaft with drive elements attached to it, i.e. gears, cams, etc. The purpose of the invention is to simplify the design and improve manufacturability. The drive elements 2 are rigidly fixed on the shaft 1. The drive elements are combined into groups and connected to each other by means of connecting sleeves 4. The shaft sections corresponding to the sections of connecting sleeves are subjected to elastic expansion. 2 hp f-ly, 1 ill.

    The invention relates to mechanical engineering, namely to drive shafts with drive elements fixed on it, i.e. gear mi, cams
    % The fSfc-rcS of the invention is the simplification of end and the improvement of manufacturability. V drawing shows a hollow shaft with drive elements, a longitudinal 10 axial section.
    Double cams 1 are mounted on the hollow shaft, each of which consists of two sections 2 forming the cams themselves and of sleeve 3 connecting them to J5. Using a hydraulic strain gauge (not shown), the sections 4 of the hollow shaft are expanded, and thereby plastically deform them. The deformation extends to the coupling sleeves 3, but only in the elastic range. By resiliently restoring the sleeves, a dynamic connection is formed, connecting the shaft and the drive elements with each other. Expansion section 4 (left 25 half of the drawing) may be limited only to that part of the hollow shaft which is located adjacent to the coupling sleeve 3, so that the elastic deformation does not extend to 30 sections 2 of the cam (or only to a small extent). There is a gap between the hollow shaft and the cams. In the right half of the drawing, the expansion portion 4 extends over the entire double cam 1. To avoid an undesirably large deformation, in particular, extending to the surface 5, the deformation portions 2 have a diameter slightly larger than the joint. Sleeve sleeves 3, so that in this case elastic deformation is practically

    it extends only to the connecting sleeves, or it is possible to provide notches 6, by means of which between the radially inner region 7, which is also subjected to elastic deformation, and the outer surface 5, bridges 8 are formed, in which there is no elastic deformation.

    1. A hollow shaft with drive elements interconnected with various degrees of tension by means of internal pressure with the formation of extended shaft sections, characterized in that
    In order to simplify the design and improve the manufacturability, a part of the drive elements is combined into groups in which the individual elements are interconnected by means of elastically expanded thin-walled connecting sleeves, with the extended shaft sections being located opposite the connecting sleeves.

    2. A shaft according to claim 1, characterized in that the drive elements are integral with the coupling sleeves.
    [3]
     3. Shaft across l characterized in that the drive elements having a cross-section that is asymmetrical with respect to the axis of rotation are made with axial recesses forming bridges with a weakened cross-section between the inner concentric portion of the drive element and the outer eccentric portion of this element in the radial direction
