Abstract
The planet wheel carrier for a planetary gearing, especially a cycle multi-speed hub, comprises two annular discs (1) of substantially like form shape-stamped out of sheet metal material which are arranged coaxially and in mirror-image to one another each comprising several circumferentially mutually offset cylindrical bearing journals (5) pressed out of the sheet metal material and bridge dogs (11) pressed out of the sheet metal material in the same axial direction between the bearing journals (5) in the circumferential direction. The bearing journals (5) of the two annular discs (1) are aligned by pairs in the mirror-image arrangement and rotatably mount the planet gear wheels (7) arranged axially between the annular discs (1). The bridge dogs (11) lie against one another and are connected firmly with one another by securing means, for example rivets (15). Toothings (17) are provided on the internal circumference of the annular discs (1) for torque transmission. A planet wheel carrier of this kind can be produced at favorable cost and without detriment to its operational reliability.
