Title:
LINK COMPONENT WITH OIL HOLE
Document Type and Number:
WIPO Patent Application WO/2019/150465
Kind Code:
A1
Abstract:
A link component 150 is mounted on a crankshaft 106 of an internal combustion engine E and has an oil hole 150E that communicates from the outer side to the crankshaft 106 side, wherein: the oil hole 150E includes an oblique surface 150F on a peripheral edge of an opening section on the crankshaft 106 side; the carbon concentration of the surface excluding the oil hole 150E is at least 0.5% by weight; and the carbon concentration of the oblique surface 150F is within a range of 0.7–0.9% by weight. Due to this configuration, the resistance of the oil hole section, where stress is likely to concentrate, is increased thereby preventing breakage, and manufacturing costs are moderated.
