Planetary gearset with multi-layer coated sun gear |
摘要 |
A planetary gearset includes a sun gear member having a sun gear body made of a steel material and an outer periphery with a plurality of teeth formed thereon. Each of the sun gear teeth has at least one mating surface for engaging mating surfaces on complementary teeth on at least one planet gear. A fatigue-resistant coating is applied to the mating surfaces of the sun gear teeth. The coating is harder and more abrasive than the mating surfaces of the planet gear teeth.
