摘要： A method includes the steps of compacting powder metal to form a powder metal blank, and forming gear teeth on the powder metal blank by rolling the powder metal blank between rolling dies rotating about parallel axes. The step of forming gear teeth on the powder metal blank by rolling includes the steps of rotating the rolling dies about parallel axes and maintaining the distance between the parallel axes constant during forming of the gear teeth on the powder metal blank. Powder metal gears having 45.degree. helical gear teeth are cold rolled. Herringbone gears and pinion gears are made with the 45.degree. helical powder metal gears.

摘要： A method is provided for forming a one-piece sheet metal toothed wheel including a central sheet metal wall of predetermined thickness and a series of integral teeth on the periphery of the central wall.The method comprises a combination of steps the initial one is cold-forming a circular piece of sheet metal into a preform having an outer annular section of generally uniform cross-sectional configuration and an integral sheet metal central wall.The next step is rotating (1) the rotary holding unit with the preform secured thereto about the preform axis, and (2) the tooth-forming tool unit about the rotational axis thereof in a predetermined rotational relation wherein the axes are parallel and the rotational speeds are synchronized. The third step is performed while the rotary holding unit with the preform secured thereto and the tooth-forming tool unit are in the predetermined rotational relation, effecting a relative movement between the units and the axes thereof in a direction toward one another to engage the tooth-forming periphery of the tooth-forming tool unit in cooperating metal-deforming relation until the sheet metal of the outer portion of the annular section is cold-formed into a series of initially-formed teeth, peripheries of the series of initially-formed teeth being cold-formed by rolling contact with the tooth-forming periphery of the tooth-forming tool unit. Each of the initially-formed teeth has a pair of oppositely disposed operative surfaces defined between a crest portion and a trough portion. The final step is to form the series of integral teeth by removing material from the pair of operative surfaces.

摘要： In forming helical splines with stoppers on a rotary shaft, its large-diameter portion is held between a pair of rolling tools, each of which comprises: a helical teeth forming die having inclined teeth; an aligning teeth die having aligning teeth which are aligned with every other inclined tooth when combined with the helical teeth forming die; and a finishing teeth die having finishing teeth which are equal in pitch to the aligning teeth. Under this condition, the shaft is rolled under pressure by moving the rolling tools, to form helical grooves, and communication grooves communicated with every other helical grooves on the large-diameter portion, leaving stoppers between the communication grooves. Hence, the helical splines are formed by one rolling operation, with burrs formed between the spline grooves and the communication grooves being automatically removed.

摘要： An apparatus allows for chamfering and deburring the end edges of a toothed production gear in a single operation and with one and the same tool. The tool includes two pressure wheels. Provided on each pressure wheel, axially side by side, are a ring of guide teeth and a ring of deburring teeth projecting circumferentially beyond the ring of the guide teeth. The rings have a filleted transition between them and together form chamfering teeth by means of which the end edges of the production wheels are pressed radially and axially against the production gear by means of adjusting drives.

摘要： An apparatus and method for forming a power transmission member from a thin-walled blank, the apparatus including a pair of dies (84) having opposed work surfaces, and a mandrel (50) positioned between the work surfaces of the dies (84) for receiving a blank (52) to be formed and rotated upon movement of the work surfaces of the dies in opposite directions during a forming operation. The mandrel (50) includes a work surface for cooperating with the work surface of the dies (84). Notch forming projections (70) on the work surfaces of the dies (84) cooperate with the work surfaces of the mandrel (50) for roll punching notches (72) through the blank (52) as the blank (52) is rotated between the moving dies (84).

摘要： A cold-formed ring gear is made from a relatively thin circular metal body, the outer peripheral edge of which is preformed to define a radially inwardly opening U-shaped channel in the outer surface of which the gear tooth pattern is subsequentially cold rolled using a known method and tooling. The unique preformed plate body obviates the need for a grooved interior supporting mandrel and results in a toothed rim of substantially enhanced strength and rigidity. The gear tooth pattern which is cold rolled in the preform provides tooth faces of substantially enhanced width and depth relative to the width and thickness of the base material from which they are formed. All of the other known advantages of cold formed teeth, as opposed to conventional cut teeth, are also realized.

摘要： In pressure forming splines or teeth in the sleeve of a clutch hub and the like, a rotatable toothed mandrel and a pair of sliding toothed racks are offset relative to one another such that when the sleeve of the clutch hub blank is placed on the mandrel, a ring-shaped lip portion of the sleeve adjacent the open sleeve end is not intermeshed between the mandrel teeth and rack teeth and thus is not splined and such that a transition region between the cylindrical oil seal surface and the sleeve is splined. The clutch hub thus includes splines on the sleeve terminating short of the open sleeve end in an unsplined ring-shaped lip portion and extending at the other end contiguous with splines formed in the transition region between the oil seal surface and sleeve. A clutch hub can thereby be manufactured having, in combination, a longitudinal tooth taper (bellmouth) within required close tolerances, e.g., within 0.010 inch, preferably within 0.005 inch, and an oil seal surface with roundness within required close tolerances, e.g., within 0.005 inch.
