Abstract
Method fastening drive elements on a hollow shaft, which comprises: pushing n drive elements with a thickness a over a hollow shaft, retaining the drive elements at mutual spacings b and in respective desired azimuthal positions by means of holding devices; providing active sections of a material with a given limit of elasticity, a length c, mutual spacings d and being bounded by sealing lips on a hydraulic expanding device so that .[.n (a+b)=n (c+d).]. .Iadd.n.a+(n-1) b=n.c+(n-1) d.Iaddend., pushing the hydraulic expanding device into the hollow shaft; and applying a pressure through the hollow shaft to the active sections stressing the material of the active sections radially beyond the given limit of elasticity.
