Wheel assembly for support of planetary gearing - has axially offset spur gears circumferentially overlapping

摘要

With two planetary wheels (6, 7) adjoining each other in the circumferential direction of a central axis the tooth width (13) is less than the tooth width of the central wheel. The spur gears (16, 17) are offset from each other both in the directions of the central axis and in the circumferential directions of the central axis with mutual overlapping. The spur gear (16, 17) of the planetary wheel (6, 7) is mounted on a hub part (19) of reduced dia. The hub parts of all the planetary wheels can be the same. USE/ADVANTAGE - Through the larger number of planetary wheels the tooth force distribution on the central wheel is more even and the service life is thereby increased.
