Abstract
A cable tensioning capstan assembly comprises a capstan drum and at least a first traction flange. The capstan drum may be configured to support a cable (e.g., a cable is configured to wrap around the capstan drum), and the capstan drum may be configured to rotate about an output axis. The first traction flange may be disposed adjacent the first axial end of the capstan drum and configured to rotate about the output axis. In various embodiments, the first traction flange is independently rotatable relative to the capstan drum. A clutch assembly between an input shaft and the first traction flange may facilitate the independent rotatability of the first traction flange.
Claims19
A cable tensioning capstan assembly comprising:
- a capstan drum around which a cable is configured to be wrapped, wherein the capstan drum is configured to rotate about an output axis and wherein the capstan drum comprises a first axial end and a second axial end;
- and
- a first traction flange disposed adjacent the first axial end of the capstan drum and configured to rotate about the output axis, wherein the first traction flange comprises a first gear track and a second gear track that circumferentially extend around a radially inward surface of the first traction flange;
- wherein the first traction flange is independently rotatable relative to the capstan drum.

A cable tensioning capstan assembly comprising
- a capstan drum comprising a radially outward surface around which a cable is configured to be wrapped, wherein the capstan drum is configured to rotate about an output axis and wherein the capstan drum further comprises a first axial end, a second axial end, and a radially inward surface, wherein the capstan drum comprises a capstan drum gear track circumferentially extending around the radially inward surface of the capstan drum;
- a first traction flange disposed adjacent the first axial end of the capstan drum and configured to rotate about the output axis, wherein the first traction flange comprises a first gear track and a second gear track that circumferentially extend around a radially inward surface of the first traction flange;
- a second traction flange disposed adjacent the second axial end of the capstan drum and configured to rotate about the output axis, wherein the second traction flange comprises a third gear track and a fourth gear track that circumferentially extend around a radially inward surface of the second traction flange;
- an input shaft configured to be rotated about an input axis, wherein the input shaft comprises a pinion, a first shaft portion, and a second shaft portion, wherein the pinion engages the capstan drum gear track to drive rotation of the capstan drum about the input-output axis;
- and
- a first clutch gear, a second clutch gear, a third clutch gear, and a fourth clutch gear, wherein the first clutch gear engages the first gear track, the second clutch gear engages the second gear track, the third clutch gear engages the third gear track, and the fourth clutch gear engages the fourth gear track;
- wherein the first traction flange and the second traction flange are each independently rotatable relative to the capstan drum;
- wherein the first clutch gear and the third clutch gear are configured to drive rotation of the first traction flange and the second traction flange, respectively, about the output axis in response to rotation of the input shaft in a first direction, with the second clutch gear and the fourth clutch gear configured to freely rotate relative to the input shaft in response to the input shaft rotating in the first direction;
- wherein the second clutch gear and the fourth clutch gear are configured to drive rotation of the first traction flange and the fourth traction flange, respectively, about the output axis in response to rotation of the input shaft in a second direction, with the first clutch gear and the third clutch gear configured to freely rotate relative to the input shaft in response to the input shaft rotating in the second direction.
