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.
