Abstract: The present invention is a variable-ratio line gear mechanism. The mechanism forms a transmission pair consisting of a driving line gear and a driven line gear, of which axes intersect at an arbitrary angle. Transmission is generated by point contact meshing movement of line teeth between the driving line gear and the driven line gear. A contact curve of the line tooth is designed in accordance with space conjugate curve meshing theory, and the designing equation is divided into an equal transmission ratio part and a variable transmission ratio part. The equal transmission ratio part provides a uniform transmission, and the variable transmission ratio part makes the transmission ratio smoothly transit. The line gear mechanism is able to provide periodically transmission with variable transmission ratio, to provide a plurality of transmission ratios during a movement period of the driven line gear, and to enable smooth transitions between respective transmission ratios in accordance with movement rules.

Abstract: A variable torque transmission includes at least one disc-shaped gear 30 having a circular toothed surface 36 with flat beveled teeth 32 that mate along radius 38 with the cone-shaped teeth of pinion gear 10 to produce an infinitely variable lever arm and thus infinitely variable torque while allowing a constant rotation ratio between the drive shafts of the flat beveled gear 30 and pinion gear 10. The result is that the drive shaft energy input may be constant and thus energy efficiency may be maximized while torque may be selectively varied.

Abstract: A Benesch transmission transmits power from an input shaft to an output shaft, wherein the input shaft defines a first axis and the output shaft defines a second axis, includes a first member including a contacting surface which extends along at least a portion of a circle. The first member is coupled to the input shaft such that, upon rotation of the input shaft about the first axis, the first member moves so that a central axis of the circle orbits the first axis, and wherein a distance between the central axis and the first axis is variable. A plurality of second members are coupled to the output shaft and extend away from the second axis. Each of the second members extends within the circle such that, upon motion of the first member relative to the first axis, contact between the contacting surface and the second members causes rotation of the output shaft about the second axis.

Abstract: A transmission device having a simplified construction as well as a higher power transmission efficiency is provided, wherein a rotational speed can be changed steplessly without interrupting a power transmission and the rotation can be reversed. In the outer periphery of the rotating shaft (2) a thread-shape spline (5) having a first inclined plane oblique to the axial direction is provided and a rotating body (3) having a spline (not-shown) engaging with the spline (5) is rotatably and externally engaged with the rotating shaft (2). One of the rotating shaft (2) or the rotating body (3) is selected as a driving side and the other is selected as a driven side and both or one of the rotating shaft (2) and the rotating body (3) are displaced in the axial direction of the rotating shaft (2). By changing the relative speed and direction of displacement between the rotating shaft and the rotating body at their displacement, a rotation of constant speed can be transmitted into the driven side at a speed changed steplessly in a possible range or in a reverse direction.
