ABSTRACT:
A planetary gear assembly is disclosed for a planetary gear transmission which also includes a sun gear and a casing. The planetary gear assembly is comprised of a ring-shaped planetary ring gear (7) and two planetary discs (6) supporting the planetary ring gear (7). Each planetary disc (6) has an outer thrust projection (17) and an inwardly projecting boss (18). The inwardly projecting bosses (18) support the inner surface of the planetary ring gear (7). The thrust projections (17) have a greater diameter than the tooth-edge circle of the planetary ring gear 7. A planetary shaft extends through planetary shaft hole (19) of the planetary discs (6) and is fixed by a carrier (4) at both ends. A unitary outer, inner-toothed ring gear (3) has an inner ring gear portion (8) and two outer cylindrical extension portions (9). The outer cylindrical extension portions (9) have a smaller diameter than the tooth-root circle of the outer ring gear portion (8). A unitary sun gear (1) has an inner sun gear portion (26) and two outer sun gear boss portions (27). The diameter of the outer surface of the sun gear boss portion (27) is smaller than the diameter of the tooth-root circle of the sun gear portion (26). The outer surfaces (20) of the thrust projections (17) of the planetary discs (6) roll on the outer surfaces (28) of the sun gear boss portions (27) as well as on the inner surfaces (21) of the outer cylindrical extension portions (9) of the outer, inner-toothed ring gear (3).
