Abstract
A gear assembly includes an actuation gear and plural separate pinion bodies. The actuation gear has first gear teeth on one or more surfaces of the gear and is configured to rotate around an actuation axis of rotation. The pinion bodies have second gear teeth configured to mesh with the first gear teeth of the actuation gear in plural separate mesh zones of the actuation gear. Each of the plural separate pinion bodies are configured to be rotated about respective pinion axes of rotation to cause rotation of the actuation gear around the actuation axis of rotation.
Claims21
A gear assembly comprising:
- an actuation gear having first gear teeth on one or more surfaces of the gear, the actuation gear configured to rotate around an actuation axis of rotation;
- and
- plural separate pinion bodies having second gear teeth configured to mesh with the first gear teeth of the actuation gear in plural separate mesh zones of the actuation gear, wherein each of the plural separate pinion bodies are configured to be rotated about respective pinion axes of rotation to cause rotation of the actuation gear around the actuation axis of rotation,
- wherein the plural separate pinion bodies are configured to be coupled with plural separate torque generating devices so the plural separate torque generating devices separately rotate the plural separate pinion bodies.

- and
- plural separate pinion bodies having second gear teeth configured to mesh with the first gear teeth of the actuation gear in plural separate mesh zones of the actuation gear, the plural separate pinion bodies are configured to be rotated about respective parallel pinion axes of rotation to cause rotation of the actuation gear around an actuation axis of rotation of the actuation gear, wherein the pinion axes of rotation are oriented perpendicular to the actuation axis of rotation,
- wherein the plural separate pinion bodies are configured to be coupled with plural separate torque generating devices so the plural separate torque generating devices separately rotate the plural separate pinion bodies.
