Clamping hub

1. A clamping hub comprising:

a body;

an aperture, defined by the body, configured to receive a shaft;

a clamp configured to secure the shaft in the aperture, the clamp comprising:

a first deformable component that defines a first portion of the aperture and configured to, when deformed, change a size of the aperture;

a second deformable component that defines a second portion of the aperture opposite from the first portion of the aperture and configured to, when deformed, change the size of the aperture; and

wherein the first deformable component and the second deformable component are defined, at least in part, by a S shaped slot formed in the body, wherein the S shaped slot forms an S shape on a plane that is tangential to an axis of the aperture.

2. The clamping hub of claim 1 , wherein the clamp further comprises:

a first fastener, configured to, when actuated, deform the first deformable component; and

a second fastener, configured to, when actuated, deform the second deformable component.

3. The clamping hub of claim 2 , wherein the first fastener engages a first threaded aperture of the first deformable component and the second fastener engages a second threaded aperture of the second deformable component.

4. The clamping hub of claim 2 , wherein the first fastener is disposed in a first concave portion of the body and the second fastener is disposed in a second concave portion of the body opposite of the first concave portion.

5. The clamping hub of claim 2 , wherein the clamp further comprises:

a third fastener, configured to, when actuated, deform the first deformable component; and

a fourth fastener, configured to, when actuated, deform the second deformable component.

6. The clamping hub of claim 1 further comprising three or more accessory mounting apertures configured to couple the clamping hub to an accessory and wherein the first deformable component is disposed at a location within a convex hull defined by locations of the three or more accessory mounting apertures.

7. The clamping hub of claim 6 , wherein the body comprises an extrusion that extends around the aperture on the first deformable component and the second deformable component.

8. The clamping hub of claim 7 , wherein the extrusion comprises a mating feature that couples to a corresponding mating feature of the accessory.

9. The clamping hub of claim 1 wherein the first deformable component and the second deformable component are portions of the body defined by a channel in the body that extends through the aperture.

10. The clamping hub of claim 1 , wherein a center of mass is located on a rotational axis of the shaft.

11. The clamping hub of claim 1 , wherein the body comprises plastic.

12. The clamping hub of claim 1 , wherein the body comprises aluminum.

13. A shaft-accessory coupling system comprising:

a shaft;

a hub comprising:

an aperture;

a clamp disposed around the aperture and configured to tighten and reduce a cross sectional area of the aperture;

wherein the clamp comprises a first gap in the hub extending from the aperture in a first direction and a second gap in the hub extending from the aperture in a second direction that is opposite the first direction, wherein a size of each the first gap and the second gap are adjustable;

wherein the first gap couples to a third gap that extends laterally from the first gap;

wherein the second gap couples to a fourth gap that extends laterally from the second gap;

wherein the third gap couples to a fifth gap that extends laterally from the third gap;

wherein the fourth gap couples to a sixth gap that extends laterally from the fourth gap;

accessory mounting apertures configured to receive coupling fasteners that couple an accessory to the hub; and

wherein the shaft is received by the aperture and secured in the aperture by the tightening of the clamp and when the clamp is tightened, positions of the accessory mounting apertures relative to one another remain substantially constant.

14. The shaft-accessory coupling system of claim 13 , wherein a size of the first gap is reduced by tightening a first fastener and wherein a size of the second gap is reduced by tightening a second fastener.

15. The shaft-accessory coupling system of claim 14 , wherein a spacing of the accessory mounting apertures is substantially a 0.544 inch by 0.544 inch square.

16. The shaft-accessory coupling system of claim 13 , wherein the hub is rotationally balanced about the shaft.
