摘要

Sun wheel (SOP1), bridge (SP1) with planet wheels (P1) and hollow wheel (HOP1), belong to stage (P1). Sun wheel (SOP2), bridge, planet wheels (P2) and the hollow wheel (HOP2) belong to stage (P2). Sun wheel (SOP2), bridge (SD) with stage planet wheels (P2-P3) and the sun wheel (SOP3), belong to stage (P3). Shaft (B) with sun wheels: (SOP1) and (SOP2) forms a unit. Shaft (D) forms a unit with hollow wheel (HOP1) and bridge (SD). Bridge (SP1) belongs to shaft (E). The hollow wheel (HOP2) belongs to shaft (A). The bridge SD comprises left, central and right faces, the central one forming the flange of the connection shaft (D), and is located between planet wheels (P2, P3) of the stage planet wheels (P2-P3) The design is further elaborated by detailing bolted connections.
