METHOD OF FASTENING DRIVE ELEMENTS ON A HOLLOW SHAFT

摘要

Method of 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), 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.
