Abstract: A method is provided for remanufacturing a transmission assembly including an output shaft having an input end positioned adjacent an input sun gear. The method includes machining a pocket into the input end of the output shaft. A first roller needle bearing is positioned inside the pocket. The input sun gear is then replaced with a modified sun gear having a protruding center support hub configured to extend into the pocket and cooperate with the first roller needle bearing, thereby supporting the output shaft to prevent tilting of the output shaft to reduce wear.

Abstract: In a method of making a rotation-symmetrical gear member, an outer edge of a circular blank is shaped to form a concentric thickened area which extends in axial direction to thereby realize a ring structure. A remaining area of the circular blank is then shaped into a cap-like structure through application of compressive forces by means of a pressure roller such that the ring structure adjoins a sidewall of the cap structure and projects outwardly in radial direction. The ring is then formed with outer teeth in opposition to the sidewall.

Abstract: A method is provided for manufacturing a compound helically toothed planet gear for a planetary gear set wherein the individual gear elements of the compound planet gear have different leads. The method identifies and utilizes the several factors affecting gear timing for compound helical planet gears having different leads to provide planet gears capable of attaining equal load share among the several gears of the planetary gear set. Specifically, the method of the present invention utilizes a mounting shoulder and bore axis to provide common locating features for use throughout the manufacturing process The method further provides for bore honing and removal of equal amounts of material from both sides of each gear tooth in the gear finishing process so as not to alter gear timing between the compound gear elements.

Abstract: A hypoid gear tooth surface design method, wherein normal lines and helical angles of two tooth surfaces are properly selected so as to position action limit curves (L3Acc) on the outer of the areas (R2t to R2h) where the tooth surfaces are formed, whereby undercut to a gear small end side can be prevented and, by setting the involute helicoids of two tooth surfaces on a pinion side to an equal lead, a pinion top land and a gear top land (z2hnull0) can be made generally equal to each other in tooth lengthwise direction, such that sharpening of the top land can be prevented.

Abstract: A full form net shape roll finished contacting machine element such as a gear or sprocket is produced from a near net shape workpiece of wrought or forged steel including teeth with an initial outer peripheral contoured surface, each having a tooth flank with a nominally involute surface and a root/fillet region with a trochoidal surface. A rolling die is rotatably supported on a first axis. With the workpiece rotatably supported on a parallel distant second axis, the rolling die is advanced in an in-feed direction to meshingly engage with the workpiece. The involute surface of each tooth of the rolling die engages the involute surface of a mating tooth of the workpiece and the tooth tip of the rolling die engaging the trochoidal root/fillet surface between adjacent mating teeth of the workpiece to effect material flow along the outer peripheral contoured surface. This process continues for all of the teeth of the workpiece.
