Title:
AUXILIARY GEAR FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2020/129211
Kind Code:
A1
Abstract:
A resin-made auxiliary gear for an internal combustion engine with which the desired backlash with a motive power transmission gear made from a metal material that the auxiliary gear meshes with is achieved even after the auxiliary gear has been immersed in lubricating oil containing a blow-by gas or dew condensation water, gear cost can be reduced, durability can be improved, and meshing sound can be reduced. An auxiliary gear 82 for an internal combustion engine meshes with a motive power transmission gear 47 that transmits driving force of a crankshaft 31 to auxiliary machinery 8 of an internal combustion engine 3, wherein the motive power transmission gear is made from an iron-based metal material and is provided so as to rotate integrally with the crankshaft, the auxiliary gear for an internal combustion engine is a resin-made gear made by injection molding into a single composition of a heat-resistant resin not containing reinforcing materials such as fibers, the auxiliary gear is provided to a rotating shaft 88 rotatably supported inside a crank case 35 that supports the crankshaft, and the gear shape of the auxiliary gear for an internal combustion engine in a completely dry state before initial use is set so that the backlash with the motive power transmission gear is greater than a prescribed minimum state when the auxiliary gear for an internal combustion engine is in a maximum swollen state of having absorbed moisture.
