Abstract:
A planetary gear arrangement of gearwheels, comprising:a gear housing; a first shaft; a second shaft arranged coaxially opposite said first shaft; an internal geared wheel that is torsionally fixedly connected to said gear housing or to a third coaxial shaft; a sun wheel that is torsionally fixedly connected to said first shaft; a planet carrier that forms, together with said second shaft, a structural unit that is rotatably supported at at least two axially spaced-apart positions; and a plurality of identical step planets, each of which comprises a larger planet wheel (16) having a relatively larger effective diameter and intermeshing with said sun wheel, a smaller planet wheel (17) having a relatively smaller effective diameter and intermeshing with said internal geared wheel and being a separate structure relative to said larger planet wheel, at least one respective highly loadable roller bearing (25, 26) arranged respectively on both sides axially in front of and axially behind a center plane of each respective one of said planet wheels (16, 17), and an additional shaft (22) that torsionally fixedly couples said larger planet wheel and said smaller planet wheel to each other while allowing limited axial and radial movement relative to each other, wherein said additional shaft (22) engages each said planet wheel (16, 17) in a positive form-locking manner in a circumferential direction.
