Document Type and Number:
Japanese Patent JP5333600
Kind Code:
B2
Abstract:
This invention addresses the problem of providing a press-fit structure and a press-fit method capable of improving the durability of a gear which press-fits into a ring part. As such, the embodiment of this invention is that, while one end side in the central axis direction of the ring gear abuts against a protrusion formed protruding on the outer side of the radial direction of the ring part from the outer circumferential surface of the ring of the ring part, and wherein the press-fit structure press-fits the inner circumferential surface of the gear into the outer circumferential surface of the ring part, when the inner circumferential surface of the gear is press-fitted into the outer circumferential surface of the ring part, there is a tensile strength reduction mechanism reducing the tensile strength generated in the lower portion of the gear teeth in at least the position of the aforementioned end side of the gear.
