<p><P>PROBLEM TO BE SOLVED: To provide a meshing gear device of a vehicle, which is composed of a pair of helical gears, and can suppress tooth face wear and suppress gear noise. <P>SOLUTION: A tooth face in a meshing start part of a drive gear 68 is cut off, and the apex O2 of a convex curved surface shape formed on the tooth face of the drive gear 68 is set in a position away from the cut-out 80 (meshing start part) so that the meshing in the meshing start part is eliminated by the cut-out 80 formed on the tooth face that corresponds to the meshing start part, thereby suppressing the tooth face wear. Moreover, since the apex O2 of the convex curved surface shape formed on the tooth face 68a of the drive gear 68 is set in a position away from the meshing start part, tooth contact 82 necessary for a gear noise performance can be secured which enables the suppression of gear noise. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
