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.
In veterinary anatomy, the term hyoid apparatus is the collective term used to refer to the bones of the tongue—a pair of stylohyoidea, a pair of thyrohyoidea, and unpaired basihyoideum [21] —and associated, upper-gular connective tissues. [22] In humans, the single hyoid bone is an equivalent of the hyoid apparatus. [23]
The front cone of a hypoid or bevel gear is an imaginary cone tangent to the inner ends of the teeth, with its elements perpendicular to those of the pitch cone. The surface of the gear blank at the inner ends of the teeth is customarily formed to such a front cone, but sometimes may be a plane on a pinion or a cylinder in a nearly flat gear.
The hyoid apparatus is the collective term used in veterinary anatomy for the bones which suspend the tongue and larynx. [1] It consists of pairs of stylohyoid, thyrohyoid, epihyoid and ceratohyoid bones, and a single basihyoid bone. [2] The hyoid apparatus resembles the shape of a trapeze, [3] or a bent letter "H".

Hypoid spiral bevel gears. A hypoid is a type of spiral bevel gear whose axis does not intersect with the axis of the meshing gear. 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 human head is an anatomical unit that consists of the skull, hyoid bone and cervical vertebrae.The term "skull" collectively denotes the mandible (lower jaw bone) and the cranium (upper portion of the skull that houses the brain).
