Abstract
Abstract A hub-to-shaft connection comprising a shaft, a hub, key means positioned directly between said hub and said shaft, first and second spaced tapered surfaces on the inside of said hub, first and second spaced collars each having a plurality of circumferentially spaced flexible tapered leaves in engagement with the first and second tapered surfaces, respectively, and screw means extending through said collars and received in said hub for moving said tapered flexible leaves into tight wedging engagement between said tapered surfaces of said hub and the outer surface of said shaft.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
225 words
A hub-to-shaft connection comprising a hub, a shaft, a tapered surface on said hub, a collar having a plurality of tapered fLexible leaf means circumferentially spaced thereon, and moving means for effecting relative axial movement between said tapered surface on said hub and said tapered leaf means in engagement therewith so as to effect a tight locking engagement between said hub and said shaft; a second tapered surface on said hub spaced from and extending in the opposite direction from said tapered surface, a second collar having a plurality of second tapered flexible leaf means circumferentially spaced thereon, and second wedge-moving means for effecting relative axial movement between said second tapered surface on said hub and said second tapered leaf means in engagement therewith so as to effect a tight locking engagement between said hub and said shaft at the location of said second leaf means, key means positioned directly between and engaging both said hub and said shaft, said key means being axially spaced on said hub from said leaf means so as to permit substantially 360* engagement between said leaf means and said hub, screw means for securing said key means to said shaft, and set screw means for securing said hub to said shaft in a predetermined axial position prior to effecting said tight locking engagement between said hub and said shaft.
