A method and apparatus for adjusting tooth flank play between two sun gears and at least two planetary gears of a bevel gear differential drive is provided in which, after establishing the operating positions of both sun gears on their sun gear shaft, each planetary gear is shifted on its shaft, previously inserted into a transverse bore of the sun gear shaft, after which the planet gears are brought into their precise operating positions relative to the sun gears and perpendicular to the sun gear shaft and are stopped there with the maintenance of an equal tooth flank play to the sun gears, by first inserting the planetary shaft into the transverse bore of the sun gear shaft in an axially displaceable manner, then placing each planetary gear on its planetary gear shaft with a previously calculated axial distance from the sun gear shaft, and then adjusting an equal tooth flank play by axial displacement of the planetary gears with their planetary gear shafts in the transverse bore and finally fixing planetary gear shafts definitively in the transverse bore.
A bevel gear differential drive comprising a sun gear shaft having a transverse bore intermediate its ends, a pair of sun gears fixed against axial movement and rotatable on said sun gear shaft on opposite sides of said bore and functionally equally spaced therefrom, at least one planetary gear shaft in said transverse bore having an end extending from each side of said bore, a planetary gear fixed on each said end extending from the bore and means on said sun gear shaft for shifting the planetary gear shaft in the bore along with the planetary gears until flank play between the planetary gears and sun gears is substantially equal, and means frictionally fixing the planetary gear shaft as a press fit against a further movement in the transverse bore of the sun gear shaft.
