Abstract
Embodiments of clamping hub are disclosed. In one embodiment, the clamping hub includes a non-circular aperture with a portion of the non-circular aperture being formed so as to be substantially flat. The clamping hub also includes a shaft securer aperture that is formed in a substantially flat wall that contributes to the substantially flat portion of the non-circular aperture.
Claims17
A shaft coupling system that includes:
- a hub with a shaft receiving aperture formed therein, the shaft receiving aperture having an end profile substantially in the shape of a capital letter “D” formed in part by at least three separate major circular arcs and a straight line;
- wherein
- an end profile of the shaft receiving aperture includes three separate curved areas and a flat area, the three separate curved areas including:
- a first curved area defining a major circular arc that comprises over half of a perimeter of the end profile;
- a second curved area disposed at a first intersection of the first curved area and the flat area, the second curved area extending outward from an expected intersection of a circle corresponding to the major circular arc and the flat area;
- and
- a third curved area disposed at a second intersection of the first curved area and the flat area, the third curved area extending outward from an expected intersection of a circle corresponding to the major circular arc and the flat area.

A hobby robotics hub comprising:
- a body having therein formed a non-circular shaft receiving aperture having a flat portion and a major circular arc portion such that the non-circular shaft receiving aperture that is substantially in the shape of a capital letter “D”;
- a shaft securer aperture formed in a substantially flat wall of the body such that the substantially flat wall contributes to the flat portion of the non-circular shaft receiving aperture;
- and
- at least three additional apertures formed in the body and situated such that a center axis of each of the three additional apertures is substantially equidistant from a center axis of the non-circular shaft receiving aperture;
- wherein the at least three additional apertures and the shaft securer aperture are coplanar;
- and
- wherein an end profile of the shaft receiving aperture includes three separate curved areas and the flat portion, the three separate curved areas including:
- a first curved area defining the major circular arc portion, the first curved area comprising over half of a perimeter of the end profile;
- a second curved area disposed at a first intersection of the first curved area and the flat portion, the second curved area extending outward from an expected intersection of a circle corresponding to the major circular arc and the flat portion;
- and
- a third curved area disposed at a second intersection of the first curved area and the flat portion, the third curved area extending outward from an expected intersection of a circle corresponding to the major circular arc and the flat portion.

A shaft coupling system, comprising:
- a hub having a shaft receiving aperture configured to slidably receive a shaft having a flat surface, the hub also including at least three additional apertures situated such that a center axis of each of the three additional apertures is substantially equidistant from a center axis of the shaft receiving aperture;
- and
- wherein the hub comprises an extrusion that extends from a body of the hub, the shaft receiving aperture being disposed through the extrusion, the extrusion having an exterior cross section shape that has multiple lines of symmetry;
- and
- an end profile of the shaft receiving aperture includes three separate curved areas and a flat area, the three separate curved areas including:
- a first curved area defining a major circular arc that comprises over half of a perimeter of the end profile;
- a second curved area disposed at a first intersection of the first curved area and the flat area, the second curved area extending outward from an expected intersection of a circle corresponding to the major circular arc and the flat area;
- and
- a third curved area disposed at a second intersection of the first curved area and the flat area, the third curved area extending outward from an expected intersection of a circle corresponding to the major circular arc and the flat area.
