BEVELOID PLANETARY GEAR DRIVE FOR TRANSFER CASE OR TRANSMISSION
摘要
<p>A method of assembling a planetary gearset includes die-forming a plurality of circumferentially spaced apart teeth on a sun gear, a planet gear and a ring gear. Each tooth includes a pair of tooth flanks in a final net form for engagement with mating gear teeth. The sun gear teeth have a conical shape to allow a first die to linearly move relative to a second die after the gear teeth are die-formed. The planet gears are mounted on a carrier. The sun gear and the planet gear are oriented such that the conical shapes of the respective gear teeth taper in opposite directions from one another and the planet gear teeth meshingly engage with both the ring gear teeth and the sun gear teeth.</p>
