JOINED SINTERED COMPACT AND PLANETARY CARRIER PROVIDED WITH THE JOINED SINTERED COMPACT

摘要

PROBLEM TO BE SOLVED: To provide a joined sintered compact in which the breakage of a projecting part can be prevented and the enlargement of the projecting part for increasing the strength of the projecting part is made needless, and which can be made compact and lightweight, and to provide a planetary carrier provided with the joined sintered compact.;SOLUTION: Provided that the height H of a projecting part 31d is defined as a longitudinal direction and the width W of the projecting part 31d in the rotational direction of annular plates 31, 32 is defined as a horizontal direction, the projecting part 31d is projected from a joined face 31c in such a manner that the aspect ratio (W/H) in the projecting part 31d reaches ≥2, and the tilted angle β of one side face A1 in the width direction of the projecting part 31d and one side face B1 on the inner circumference of a recessed part 33a to which power A transferred from an annular plate 32 to an annular plate 31 is high is made narrower than the tilted angle α of the other side face A2 in the width direction of the projecting part 31d and the other side face B2 on the inner circumference of the recessed part 33a to which power B transferred from the annular plate 32 to the annular plate 31 is small.;COPYRIGHT: (C)2010,JPO&INPIT
