<p>#CMT# #/CMT# 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. #CMT#USE : #/CMT# Planet pinion carrier for receiving planetary gears of planetary gear stage for vehicle. #CMT#ADVANTAGE : #/CMT# Since the connecting bars are tapered between the carrier portions, the material burden in end region of the welded joints can be prevented effectively and the turbulence of the oil mist can be enhanced. Thus the structural strength and mechanical performance of the pinion carrier can be improved efficiently. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of the pinion carrier. 1,2 : Carrier portions C1,C2,C3,C4 : Connecting bars F : Planetary gear windows W1,W2,W3,W4 : Welded joints b1 : Circumferential direction measured width of connecting bars b2 : Circumferential direction measured width of welded joints.</p> |
