| 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. | ||||||

| 118 | Method of generating involute tooth forms with a milling cutter | US485408 | 1983-04-15 | US4565474A | 1986-01-21 | Paul A. S. Charles |
| An involute external tooth profile is cut into the periphery of a gear blank by positioning a rotating milling cutter with its cutting path perpendicular to the plane of action of the desired base surface of revolution within the gear blank so as to penetrate the plane of action from the side thereof opposite to the base surface and with a predetermined line of intersection which generates the involute profile as the base surface rolls upon the plane of action. The rolling action causes the generating line to traverse the blank between its addendum surface and a depth sufficient to provide the desired length of active profile. | ||||||

| A method and apparatus for grinding pairs of gear wheels such as spiral or curved tooth bevel gear wheels whereby a first wheel is ground with a male cup-type grinding tool and a second, counter wheel is ground with a female cup-type grinding wheel with an additional eccentric cyclic motion being applied to one of said wheels. In accordance with a preferred feature of the invention, the grinding tools utilized are not exactly complementarily congruent, the female tool differing by an amount that is equal to the amount of the additional eccentric cyclic motion that is effective in the direction of the tooth normal. The additional eccentric motion is preferably elliptical and in accordance with an apparatus aspect of the invention a drive is provided for achieving such elliptical supplementary motion. This drive is preferably characterized by a rod of specific length that is swingably borne and rotatably driveable at one end, about a rod axis that is stationary on the device (corresponding to the grinding axis when there is no supplementary motion), while at the other end of the rod there is a pivot arm of specific pivot length that is swingably and rotatably borne about a pivot axis (that consequently moves with reference to the machine frame), the grinding axis being guided by the free end of the pivot arm. | ||||||
| 120 | Bevolute gear system | US156107 | 1980-06-03 | US4367058A | 1983-01-04 | Willis M. Carter |
| The present invention relates to a bevolute gearing system which transmits torque between non-intersecting shafts at right angles to each other. The bevolute gear system includes a pinion gear which is flat and in one plane. The pinion gear is designed to include teeth which are shaped in the form of an involute spiral. The bevolute gear system includes a second gear which is also designed to include teeth which are shaped in the form of an involute spiral. The second gear is mounted on a non-intersecting axis at a right angle to the axis of the pinion gear. The bevolute gearing system of the present invention reduces the thrust loads to negligible values for the bearings of both the pinion gear and the second gear. In addition,. higher mechanical efficiencies, wider tolerances on alignment of the gears, interchangeability between the gear and the pinions to produce different ratios and a substantially eliminated gear noise are a few of the many advantages disclosed in the present invention. | ||||||
