GEAR MECHANISM AND MANUFACTURING METHOD OF GEAR MECHANISM |
摘要 |
In a gear mechanism that includes a gear in which a tooth trace is twisted at a predetermined angle with respect to an axial direction, a curvature radius along a line of contact at a meshing position where a line of contact does not intersect a pitch circle is formed larger than a curvature radius along a line of contact at a meshing position where a line of contact intersects a pitch circle, on a plane of action of the gear. |

1. A gear mechanism comprising:
a helical gear in which a first curvature radius along a first line of contact at a meshing position where a line of contact does not intersect a pitch circle is larger than a second curvature radius along a second line of contact at a meshing position where a line of contact intersects a pitch circle, on a plane of action of the helical gear. |
