摘要： A degree of freedom of a hypoid gear is improved. An instantaneous axis in a relative rotation of a gear axis and a pinion axis, a line of centers, an intersection between the instantaneous axis and the line of centers, and an inclination angle of the instantaneous axis with respect to the rotation axis of the gear are calculated based on a shaft angle, an offset, and a gear ratio of a hypoid gear. Based on these variables, base coordinate systems are determined, and the specifications are calculated using these coordinate systems. For the spiral angles, pitch cone angles, and reference circle radii of the gear and pinion, one of the values for the gear and the pinion is set and a design reference point is calculated. Based on the design reference point and a contact normal of the gear, specifications are calculated. The pitch cone angle of the gear or the pinion can be freely selected.

摘要： A hypoid gear device and a final reduction gear for a vehicle. The drive pinion (12) of the final reduction gear (10) having a hypoid gear is formed of a gear having a cylindrical outline. A drive pinion shaft (16) is projected from both sides of the drive pinion (12), and the drive pinion is supported on bearings (18) and (20) at these both projected portions. Since the outline of the drive pinion is formed in a cylindrical shape, the drive pinion can adopt a both side supporting structure. Thus, the deflection of the shaft can be suppressed and a bearing load can be lowered.
