  • Patent number: 5470166
    Abstract: A press fit joint shafting connection for hollow cylindrical steel shafts has shaft end faces provided with eccentrically arranged axial recesses wider than the main shaft bores. An annular toughened steel locking insert having an eccentrically arranged through bore is retained in the space formed by the eccentrically arranged bores when the shaft ends meet. The degree of eccentricity of the bore in the locking insert corresponds to that of the eccentrically arranged shaft recesses while the locking insert bore diameter corresponds to the diameter of the main shaft bores. The inner bores with free lumen are in alignment in a mounted state. A corresponding shafting method is also described.
