Title: PLANET CARRIER FOR A SPEED-REDUCING UNIT WITH AN EPICYCLIC GEAR TRAIN
Abstract:
Planet carrier (18) for a speed-reducing unit with a planetary gear set (10), comprising a torque transmission part (24) having a longitudinal axis A and an annular cage (26) extending about the axis A and connected to one longitudinal end of the part (24). The cage (26) comprises two flanks (28, 30) extending substantially radially relative to the axis A and connected by curved members (32), seats (36) extending axially between the flanks (28, 30) and being intended for carrying planet wheels (20) mounted rotatingly about the seats (36). The curved members (32) comprise bars (33, 34) which are each inclined relative to a longitudinal plane passing through the axis A and substantially through the corresponding bar (33, 34).
