A hub clamp assembly includes a hub that has a flange portion and an annular sleeve portion. The sleeve portion has a plurality of substantially longitudinal slits therein extending from a distal end toward the flange portion to form a plurality of sleeve segments. The sleeve portion further has an outer surface that includes a first set of surface features. The assembly also includes an annular collar that has one or more sleeve engagement pieces each having a first surface and an opposing second surface. The first surface of the sleeve engagement piece contains a second set of surface features configured to correspond to and engage the first set of surface features of the sleeve portion of the hub. A support ring surrounds the sleeve portion of the hub and overlies the second surface of the sleeve engagement pieces.

1. A hub clamp assembly comprising: a hub, the hub comprisinga flange portion, andan annular sleeve portion, the flange portion and annular sleeve portion together defining a common passageway through the hub, the sleeve portion having a plurality of substantially longitudinal slits therein extending from a distal end toward the flange portion to form a plurality of sleeve segments, the sleeve portion further having an outer surface comprising concentric, unthreaded grooves; andan annular collar, the annular collar comprising:a plurality of sleeve engagement pieces together substantially surrounding the sleeve portion, each sleeve engagement piece having a first surface and an opposing second surface, the first surface containing concentric, unthreaded grooves slidably engaged with the concentric, unthreaded grooves of the outer surface of the sleeve portion, anda support ring surrounding the sleeve portion of the hub and overlying the second surfaces of the sleeve engagement pieces;wherein each sleeve engagement piece includes a lip intermediate the flange portion and the support ring and wherein the hub and annular collar are configured to cooperatively clamp a shaft within the common passageway through the hub,wherein the hub is provided with a plurality of threaded members in the flange portion for engaging the lip of the sleeve engagement piece, the lip in turn contacting a facing surface of the support ring to apply an axial force thereto, the threaded members urging the collar axially away from the flange portion to an operative position along the length of the sleeve portion such that the grooves of the sleeve engagement pieces slide against the grooves of the sleeve portion, thereby forcing the sleeve engagement pieces radially inward to exert a clamping force. 2. The assembly of claim 1, wherein the sleeve portion is keyless. 3. The assembly of claim 1 having from two to five sleeve engagement pieces. 4. The assembly of claim 1, wherein the support ring comprises two separate support ring units. 5. A hub clamp assembly comprising: a hub, the hub comprising:a flange portion having a plurality of apertures about its periphery configured to be attached to a mechanical device to which rotational energy is to be transferred from a shaft, andan annular sleeve portion, the flange portion and annular sleeve portion together defining a common passageway through the hub, the sleeve portion having a plurality of substantially longitudinal slits therein extending from a distal end toward the flange portion to form a plurality of sleeve segments, the sleeve portion further having an outer surface comprising concentric, unthreaded grooves; andan annular collar, the annular collar comprising:a plurality of sleeve engagement pieces together substantially surrounding the sleeve portion, each sleeve engagement piece having a first surface and an opposing second surface, the first surface containing concentric, unthreaded grooves slidably engaged with the concentric, unthreaded grooves of the outer surface of the sleeve portion, anda support ring surrounding the sleeve portion of the hub and overlying the second surfaces of the sleeve engagement pieces, the sleeve engagement piece including a lip intermediate the flange portion and a facing surface of the support ring, the lip in contact with the facing surface of the support ring;wherein a plurality of threaded members extend through the flange portion to engage the collar, the threaded members configured to cause axial movement of the collar with respect to the sleeve segments such that the grooves of the sleeve engagement pieces slide against the grooves of the sleeve portion, thereby forcing the sleeve engagement pieces radially inward to exert a clamping force on the shaft. 6. The assembly of claim 5, wherein the plurality of threaded members are configured to urge the collar axially away from the flange portion to force the sleeve engagement pieces radially inward to exert the clamping force.
