Planetary gear mechanism
First Claim
1. A planetary gear mechanism for converting a slow rotational movement of a drive shaft into a rapid rotational movement of an output shaft, the planetary gear mechanism comprising:
- a planetary gear carrier;
a planetary gear; and
a bearing arrangement arranged on the planetary gear carrier and configured to rotatably mount the planetary gear, the bearing arrangement including;
at least two tapered roller bearings arranged spaced apart axially from one another between the planetary gear and the planetary gear carrier, each of the at least two tapered roller bearings having an inner ring and an outer ring;
a first intermediate ring configured to axially position the at least two tapered roller bearings on the planetary gear carrier, the first intermediate ring arranged on an outer circumferential face of the planetary gear carrier between the two inner rings;
a collar formed on an inner circumferential face of the planetary gear between the two outer rings radially along an inner circumference of the planetary gear, the collar configured to axially secure the planetary gear; and
at least one second intermediate ring configured to axially position the at least two tapered roller bearings with respect to one another, the at least one second intermediate ring arranged on the inner circumferential face of the planetary gear, the at least one second intermediate ring having;
an outer circumferential face; and
a cutout formed on the outer circumferential face and directed to the collar, the cutout configured to correspond at least to an axial length of the collar.

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.
