  • Vehicle differential
    Patent number: 10012302
    Abstract: A vehicle differential includes a pair of side gears, a pinion gear, a differential case, and an annular ring gear. The differential case includes an opening penetrating a peripheral wall of the differential case. The annular ring gear is attached to an outer side of the peripheral wall of the differential case such that a central axis of the annular ring gear and a rotational axis of the differential case coincide with each other. The annular ring gear includes a protrusion on an inner peripheral edge of the annular ring gear. The protrusion covers a part of the opening when viewed in a penetration direction of the opening. The protrusion protrudes toward the inner side of the opening in the radial direction of the rotational axis as compared with an other part of the inner peripheral edge of the annular ring gear that has no protrusion.

  • Gear device
    Patent number: 9593758
    Abstract: A gear of a gear device includes a plurality of teeth having tooth surfaces. The tooth surfaces are shaped such that contact length ratios of three or more of the teeth are outside a predetermined range centered on an average value of the contact length ratios of all of the teeth, where the contact length ratio is obtained by dividing a contact length of a tooth contact face by a diagonal length of a plane of action.
