Abstract
The disclosure is directed to a method of manufacturing a power transmission device that can include forging to form a planetary carrier plate integrated with dog teeth, sintering to form a planetary carrier, and joining the planetary carrier plate to the planetary carrier by brazing the planetary carrier plate to the planetary carrier at support parts arranged in a circumferential direction at a peripheral edge part of the planetary carrier so that the planetary carrier plate is fixed to face the planetary carrier on a side of the planetary carrier where a pinion gear is positioned. The method can further include sintering the planetary carrier plate and the planetary carrier, forming a pinion shaft hole for mounting a pinion shaft that constitutes the pinion gear in the planetary carrier plate and the planetary carrier, and performing high-frequency quenching on the dog teeth of the planetary carrier plate.
