摘要： An apparatus for producing pairs of spur gears by cutting tooth gaps with a rotating end cutter head or face milling cutter, wherein, in order to manufacture the one spur gear, one of the elements--the spur gear or the end cutter head--carries out an arcuate or circular rolling movement about an axis which coincides or approximately coincides with the gear axis of the other gear, and the other gear is produced by a cutting-in depth or plunge cut operation without any rolling movement.

摘要： Formations on a workpiece (1) are machined along an arcuate path (5) having a center (4) in eccentrically spaced relation to a rotational axis (3) about which the workpiece is indexed by a holder (2). A tool (7) is controllably displaced through its carrier (12) in such a manner as to establish radial alignment of the tool relative to the indexing axis and the path center during operational strokes to enable machining of identical formations spaced along the path. The radius of curvature of the path is greater than the maximum distance (4-14) to which said operational strokes are limited.

摘要： A gear including plural teeth 3 to mesh with teeth of a corresponding gear to thereby transmit a rotational motion is provided. A form (b) of a tooth root side of each tooth 3 includes: a first curved surface c that is smoothly connected to a tooth surface a having an involute curve and has a profile expressed by a curve that is convex in an inverse direction of the involute curve of the tooth surface a; and a second curved surface d that is smoothly connected to the first curved surface c and has a profile defined by a hyperbolic function having a curve being convex in the same direction as the first curved surface c. It is possible to reduce a stress generated on the tooth root side at the time of meshing with teeth of the corresponding gear and thus to increase the strength of the teeth.

摘要： A gear cutter is provided as an accessory to a milling machine. A single gear cutting blade makes successive passes across a continuously rotating gear blank to cut a desired number of gear teeth. The cycle time of the cutting blade and the angular velocity of the gear blank are such that the gear blank increments a number of cut positions after each cut which number is greater than one and prime to the total number of gears to be cut. The accessory includes a pivotal and oscillating gear blank carriage. A blank on the carriage is rotated through change gears by a main timing shaft. The timing shaft also controls vertical movement of the cutting blade through a cam, a rack and pinion assembly and change gears. Further, through another cam the timing shaft controls retraction of the gear blank from the cutter blade. Proper selection of change gears enables cutting of gears of any pitch or diameter.
