Abstract:
A device for mounting or positioning a machine element having a bore upon a shaft element comprising a one-piece outer sleeve for engaging the machine element associated with said outer sleeve, having a uniform outside diameter and having a tapered internal surface,a one-piece inner sleeve having a uniform inside diameter for encircling the shaft element associated with said inner sleeve, and having a tapered external surface matching the tapered internal surface of said outer sleeve, and at least one axial slot extending longitudinally along at least a first of said inner and outer sleeves to permit adjustment of the uniform diameter of said first sleeve in one direction to effect interlocking of said first sleeve with its associated element and in the opposite direction to release said interlocking, each of said inner and outer sleeves having an annular radial end face and threads adjacent said end face, and an adjuster having first threads and a first annular radial abutment face adjacent said first threads, said adjuster first threads adapted to engage the threads of one of said inner and outer sleeves and said adjuster radial abutment face adapted to engage the radial end face of the other of said inner and outer sleeves, whereby tightening of said adjuster on said one sleeve effects relative axial displacement of said sleeves, the relative axial displacement of said matching tapered surfaces of said sleeves adjusting the uniform diameter of said first sleeve.
