Abstract
An energy conversion device may include a shaft including a first portion and a second portion wherein the first portion of the shaft is configured to rotate relative to the second portion of the shaft. A rotor may be coupled to the first portion of the shaft and a stator may be coupled to the second portion of the shaft. A first one-way bearing may be coupled to the first portion of the shaft and configured to transfer rotational input to the first portion of the shaft in a first direction. A second one-way bearing may be coupled to the second portion of the shaft and configured to transfer rotational input to the second portion of the shaft in a second direction opposite the first direction.
Claims20
An energy conversion device comprising:
- a shaft including a first portion and a second portion wherein the first portion of the shaft is configured to rotate relative to the second portion of the shaft;
- a coupler extending coaxially with the shaft, the coupler extending from a first lateral end of the first portion into a second lateral end of the second portion, the coupler configured to position the first portion radially relative to the second portion;
- a rotor coupled to the first portion of the shaft;
- a stator coupled to the second portion of the shaft;
- the first portion of the shaft configured to transfer a first rotational input to the rotor in a first direction;
- and
- the second portion of the shaft configured to transfer a second rotational input to the stator in a second direction opposite the first direction.
A rotational assembly comprising:
- a shaft, the shaft including a first portion axially aligned with a second portion, wherein the first portion is configured to rotate relative to the second portion;
- and
- a first input arm coupled to the shaft through at least two one-way bearings, wherein a first one-way bearing is coupled to the first portion of the shaft and positioned in a first direction and a second one-way bearing is coupled to the second portion of the shaft in a second direction opposite the first direction.
A generator comprising:
- a shaft including a first portion and a second portion wherein the first portion of the shaft is configured to rotate relative to the second portion of the shaft;
- a rotor coupled to the first portion of the shaft;
- a stator coupled to the second portion of the shaft;
- and
- an arm operatively coupled to the first portion of the shaft and the second portion of the shaft and configured to convert oscillating linear motion to a rotational input in a first direction into the first portion of the shaft and to convert the oscillating linear motion to a rotational input in a second direction into the second portion of the shaft, where the rotational input in the second direction is in a rotational direction opposite the rotational input in the first direction.
