Abstract: A gear system for mechanically transforming motion on an infinitely variable basis as desired, having a unique arrangement of gear elements and clutches between the input and output shafts (1 and 6). A first set of gears (2) divides the motion put into the system through the input shaft (1). A controller (7) sets the phase shift in the division of motion from the first set of gears (2). Sets of non-circular gears (3) connecting the intermediate shafts (9) to "on/off" clutches (4) transform the motion output from the first set of gears (2). Finally, the resulting motion from the clutches is transferred to an output shaft (6) through a third set of gears in a summing device (5). Shaft (6) is connected to a load (not shown). The output shaft (6) is connected to the input shaft (1) by means of an "on/off" clutch (8) which is normally disengaged during variable motion transformation, but which can be engaged when the same output motion as input motion to the system is desired, without loading any of the gears during such equal motion operations.

Abstract: A method for manufacturing a variable-diameter gear pair operable with a conjugate action therebetween includes the steps of providing a first workpiece and a second workpiece, each having a minor and a major diameter portion in spaced relation therefrom along a longitudinal axis. At least one gear tooth is formed within the first (second) workpiece for forming at least one first (second) gear body, wherein the at least one gear tooth within the first (second) at least one gear body curves outwardly in a radial and axial direction from the longitudinal axis, and wherein each of the at least one gear tooths includes a width dimension that changes in size between the minor and major diameter portions. Each of the first and second at least one gear bodies has the variable diameter and variable pitch for forming a gear pair operable with each other with a conjugate action therebetween.

Abstract: A speed selector (24, 25, 40) actuates a computer (32, 35, 38, 39) to calculate optimum engine speed, speed-change rate and gear ratio for achieving a selected speed of a motor vehicle (18). An actuator (36) then accomplishes throttling of an engine (19) with a throttling means (20) and gear changes of a transmission (21) as necessary to achieve the selected vehicle speed with least-possible fuel consumption and exhaust smog. When a desired change in speed is made, it is maintained in a cruise-control mode with optimized rates of change of throttling and gear-shifting for necessary changes in engine speed for varying terrain and driving conditions.

Abstract: A method of gear design perfects design of gear teeth geometry (30) instead of limiting gear-tooth design to present cutter geometry and manufacturing methods. A pair of varied-diameter cutters (22, 29), such as hypoid cutters, have a geometric form that generates variable diameter toothed elements. Structures of hypoid or other varied-diameter cutters are achieved with a cutting tool (9) having a design cross-sectional shape of an idealized space between gear teeth on both of a pair of cutters. The cutter tool is rotated and reciprocated in shaping or machining relationship to other cutter blanks (18) or workpiece (10) in design rotation on cutter axes of a cutting-machine spindle (5). The cutter axes have variable heights above the cutter tool. Simultaneously with shaping or machine cutting either cutter blank, the angle of reciprocation and linear positioning of the cutter tool and height of center of the cutter axes are varied designedly. Appropriate cutting edges (33, 34) are then formed on or attached to the varied-diameter cutter so formed. Pairs of gear blanks are then cut to perfected gear form by the pair of varied-diameter cutter tools. The same method and machine used for making varied-diameter cutters can be employed for cutting gears (26, 27, 28) directly. The machine can also be used to manufacture dies or molds to produce toothed bodies. The method is based on general new mathematical formulations for conjugate surfaces in space for any motion or load transmission between generally oriented axes.
