Abstract
A coupling for shafts and the like, comprising a sleeve having a passage adapted to receive the end portions of two aligned shafts, an outer circumferential surface having two axially spaced sections which conically diverge towards each other, and a radial flange intermediate the sections; a pair of pressure rings each surrounding one of the sections and having a conically tapering inner circumferential surface complementary to the respectively surrounded section; and bolts connecting the pressure rings with the flange and operative for pulling the pressure rings axially towards each other and towards the flange to thereby compress the sleeve radially inwardly into frictional engagement with shaft end portions located in the passage.
