Abstract
An oscillating reversible motor providing a novel means of converting oscillating motion into selectable clockwise or counterclockwise rotary motion. More particularly, the invention presents a novel approach to a foot or hand pedal driven apparatus with which a traditional rotary water propeller or other output device may be employed in both forward and reverse directions of relative motion.
Claims16
A motor for the conversion of an oscillating input to a rotary output which is reversible by user selection, comprising:
- one or more oscillating torque inputs;
- one or more torque conversion units, comprising:
- an inner cam lobe configured to transfer torque to a rotary shaft;
- a bell housing configured to apply torque and freewheel on alternating phases of the oscillating torque inputs;
- a directional selection switch configured to select the rotational direction of torque output;
- and
- a drive shaft configured to transfer the selected unidirectional rotational torque to an output device.
4 more elements
An oscillating reversible motor comprising:
- a first input lever connected to a second input lever and operable to apply torque to a first torque conversion unit on a forward stroke and return on a backstroke;
- the first torque conversion unit configured to apply torque to a rotatable shaft on the forward stroke of the first input lever and disengage from the rotatable shaft and freewheel during the backstroke of the first input lever;
- the second input lever operable to apply torque to a second torque conversion unit on a forward stroke of the second input lever and return on a backstroke;
- the second torque conversion unit configured to apply torque to a rotatable shaft on the forward stroke of the second input lever and disengage from the rotatable shaft and freewheel during the backstroke of the second input lever;
- and
- wherein the first and second input levers oscillate to rotate the rotatable shaft in a single direction.
3 more elements
A method of converting oscillating motion into rotary motion comprising:
- connecting a first input device to a second input device with each of the first and second input devices oscillating from a forward stroke to a backstroke;
- applying torque to a first torque conversion unit from the forward stroke of the first input device;
- freewheeling the first torque conversion unit on the backstroke of the first input device;
- applying torque to a second torque conversion unit from the forward stroke of the second input device;
- freewheeling the second torque conversion unit on the backstroke of the second input device;
- biasing the rotational direction of the applied torque from the first and second torque conversion units to a single rotational direction;
- and
- rotating a drive shaft in the single rotational direction from the applied torque of the first and second torque conversion units.
