The shape of a hypoid gear is a revolved hyperboloid (that is, the pitch surface of the hypoid gear is a hyperbolic surface), whereas the shape of a spiral bevel gear is normally conical. The hypoid gear places the pinion off-axis to the crown wheel (ring gear) which allows the pinion to be larger in diameter and have more contact area.
Hypoid gear sets have long been used in the differential of rear-wheel drive cars, trucks and robotic arms.The scope of misalignment between the centers of the two interlinking shafts permits utilization of larger sized gears which enhances the contact surface area and reduces the wear and tear on the gear hence extending the life and power transmission capabilities of the gearboxes.
Hypoid gear. The gears in a matching pair are said to be skew if their axes of rotation are skew lines-- neither parallel nor intersecting. In this case, the best shape for each pitch surface is neither cylindrical nor conical but a portion of a hyperboloid of revolution. [35] [36] Such gears are called hypoid for short. Hypoid gears are most ...
