FULL TORQUE CRANK ASSEMBLIES

摘要

A crank assembly, comprising: a connecting rod; first gear; second gear; geared rotational guide; and crank journal. The connecting rod may have a gear end, which may be substantially oblong in shape. The oblong gear end of the connecting rod may comprise a geared interior surface, which may be configured to matingly engage with the first gear. The geared interior surface may comprise a long side length and a short side length, which is greater than a diameter of the first gear. The crank journal may be within the first gear, which may be configured to be in moveable but continuous contact with the geared interior surface. The first gear is connected to the second gear, such that when the first gear is rotated the second gear is also rotated. The second gear may matingly engage with and rotationally move within the geared interior surface of the geared rotational guide.

1. A crank assembly, comprising:
a connecting rod; a first gear; a second gear; a geared rotational guide; and a crank journal; wherein said connecting rod has a gear end and wherein said gear end of said connecting rod is substantially oblong in shape; wherein said oblong gear end of said connecting rod comprises a first geared interior surface; wherein said first geared interior surface of said oblong gear end of said connecting rod is configured to matingly engage with said first gear; wherein said first geared interior surface of said oblong gear end of said connecting rod has a long side length and a short side length; wherein said short side length is greater than a diameter of said first gear; wherein said crank journal is rotateably received by said first gear; wherein said first gear is configured to be in moveable but continuous contact with said first geared interior surface of said oblong gear end of said connecting rod; wherein said first gear is connected to said second gear, such that when said first gear is rotated said second gear is also rotated; wherein said second gear is configured to matingly engage with and rotationally move within a second geared interior surface of said geared rotational guide; and wherein said second gear's motion along said second geared interior surface of said geared rotational guide causes said crank journal to move in a substantially circular motion.
