Planet pinion carrier for receiving planetary gears for vehicle, has connecting bars that are tapered between carrier portions such that circumferential direction measured width of connecting bars is smaller than that of welded joints
Planet pinion carrier for receiving planetary gears for vehicle, has connecting bars that are tapered between carrier portions such that circumferential direction measured width of connecting bars is smaller than that of welded joints
The pinion carrier has several connecting bars (C1,C2,C3,C4) that are arranged along outer periphery of a carrier portion (2) while leaving planetary gear windows (F) and are formed integrally with the carrier portion (2). The ends of the connecting bars are connected to a carrier portion (1) over welded joints (W1,W2,W3,W4). The connecting bars are tapered between the carrier portions such that circumferential direction measured width (b1) of the connecting bars in the tapered region is smaller than circumferential direction measured width (b2) of the welded joints.
