Abstract
An assembly comprising a crank configured to rotate about an output axis; a first motor configured to rotate a first screw; and a first nut assembly configured to translate along the first screw in response to rotation of the first screw. The first nut assembly is coupled to the crank. The assembly further includes a second motor configured to rotate a second screw; and a second nut assembly configured to translate along the second screw in response to rotation of the second screw. The second nut assembly is coupled to the crank. Translation of the first nut assembly along the first screw is out of phase with translation of the second nut assembly along the second screw.
Claims27
An assembly comprising:
- a frame;
- a motor coupled to the frame and movable with respect to the frame about a pivot axis;
- a screw rotationally driven by the motor;
- a nut coupled to the screw and configured to translate along the screw in response to rotation of the screw;
- and
- a crank configured to rotate relative to the frame about an output axis;
- wherein the nut is coupled to the crank and configured to drive the crank about the output axis;
- and
- a carriage positioned between the nut and the crank, wherein the carriage translates along the screw with the nut;
- and wherein the carriage rotates relative to the crank about a carriage axis;
- and
- wherein the motor is movable with respect to the output axis of the crank about the pivot axis.
