Abstract: 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.

Abstract: A hypoid gear tooth surface design method, wherein normal lines and helical angles of two tooth surfaces are properly selected so as to position action limit curves (L3Acc) on the outer of the areas (R2t to R2h) where the tooth surfaces are formed, whereby undercut to a gear small end side can be prevented and, by setting the involute helicoids of two tooth surfaces on a pinion side to an equal lead, a pinion top land and a gear top land (z2h=0) can be made generally equal to each other in tooth lengthwise direction, such that sharpening of the top land can be prevented.

Abstract: 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.

Abstract: A method of evaluating motion characteristics of a workpiece gear, wherein the amount of tooth profile deflection of the workpiece gear in a direction substantially perpendicular to a surface of each tooth of the gear is obtained in relation to an angle of rotation of the gear, and a differentiated value of the amount of tooth profile deflection is obtained by differentiating the amount of tooth profile deflection by the angle of rotation. The motion characteristics of the gear are evaluated based on the differentiated value. Also disclosed in an apparatus for practicing the method.
