Abstract:
An article of manufacture comprising:a first shaft provided with a flange having a through bore,a second shaft provided with a flange having a blind bore aligned with the through bore in the flange of the first shaft,a coupling device including an adapting bolt having an external tapered surface and an axial hole open at the narrower end of the adapting bolt and a cylindrical sleeve element having an internal tapered surface corresponding to the external tapered surface of the adapting bolt, the adapting bolt being within the sleeve element and the coupling device being located in the aligned bores so that the narrower end of the adapting bolt is toward the flange of the first shaft and an end surface of the sleeve element is exposed through the bore in the flange of the first shaft,a means for engaging the adapting bolt at the axial hole and applying a force tending to displace the adapting bolt relative to the sleeve element in the direction from the wider end of the adapting bolt toward the narrower end thereof, anda separate end piece in the blind bore and having an annular abutment shoulder for engaging the sleeve element and surrounding a recess for receiving the adapting bolt with a clearance fit, whereby the adapting bolt can be moved relative to the sleeve element in the direction from the narrower end of the adapting bolt toward the wider end thereof without interference from the end piece.
