Abstract An interchangeable universal-type hub useable with an assortment of shaft-carried products such as sprockets, pulleys, sheaves, gears, couplings and the like comprising a male sleeve and a female collar, wherein the sleeve has an axial shaft-receiving bore with a longitudinally extending keyway and an exterior toothed surface formed by circumferentially spaced longitudinally extending spline grooves that define wide uniform teeth, each of sufficient width circumferentially to bridge or nestingly accommodate an interior bore keyway in radial registry and wherein the collar has an axial sleeve-receiving opening correspondingly formed with circumferentially spaced longitudinally extending spline teeth to mate with the splined grooves and wide intermediate teeth of the sleeve in nonrotatable, torque-transmitting, press-on relation. The wide teeth of the sleeve preferably do not exceed eight in number. There are carefully selected tolerances between the sleeve and mating components and the sleeve and collar of the device may be bonded in complete assembly by an anaerobic sealant.
An interchangeable, universal-type hub for shaft-carried products comprising a sleeve having a shaft-receiving bore with a longitudinally extending keyway and exterior, circumferentially spaced, longitudinally extending spline grooves defining therebetween wide uniform block, teeth each of sufficient width circumferentially that a tooth in radial registry with said keyway will accommodate the same, and a collar with an axial sleeve-receiving opening correspondingly formed with circumferentially spaced, longitudinally extending spline teeth, mating with the spline grooves and the wide teeth therebetween of the sleeve mounted thereon in non-rotatable, torque-transmitting, press-on relation; the tolerance between said sleeve and said collar being in the order of approximately 0.005 inch; and the tolerance between the torque-transmitting sides of the spline grooves of said sleeve and the mating collar''s spline teeth being in the order of approximately 0.00075 inch providing clearance between said concentric mating sleeve and collar for a sealant; the uniform block teeth of said sleeve numbering not more than eight for full torque capacity and capable of being fashioned by a single thread hob to assure invariable mating of both new and replacement components.
