Abstract
A planetary gear mechanism converts rotational movement of a drive shaft into rotational movement of an output shaft. The mechanism includes a planetary gear carrier, a planetary gear, and a bearing arrangement. The bearing arrangement includes roller bearings spaced apart between the planetary gear and planetary gear carrier. Each roller bearing has an inner ring and outer ring. The bearing arrangement includes a ring to position the roller bearings on the planetary gear carrier and a collar to secure the planetary gear. The ring is on an outer face of the planetary gear carrier between the inner rings. The collar is on an inner face of the planetary gear between the outer rings. An intermediate ring on the inner face of the planetary gear positions the roller bearings. The intermediate ring has a cutout directed to the collar which corresponds to an axial length of the collar.
