Non-circular gear example Another non-circular gear. A non-circular gear (NCG) is a special gear design with special characteristics and purpose. While a regular gear is optimized to transmit torque to another engaged member with minimum noise and wear and with maximum efficiency, a non-circular gear's main objective might be ratio variations, axle displacement oscillations and more.
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.
A crossed helical gear is a gear that operate on non-intersecting, non-parallel axes. The term crossed helical gears has superseded the term spiral gears. There is theoretically point contact between the teeth at any instant. They have teeth of the same or different helix angles, of the same or opposite hand.
Helical gears can be meshed in parallel or orientations. The former refers to when the shafts are parallel to each other; this is the most common orientation. In the latter, the shafts are non-parallel, and in this configuration the gears are sometimes known as "skew gears". An external contact helical gear in action
Bevel gears are gears where the axes of the two shafts intersect and the tooth-bearing faces of the gears themselves are conically shaped. Bevel gears are most often mounted on shafts that are 90 degrees apart, but can be designed to work at other angles as well. [1] The pitch surface of bevel gears is a cone, known as a pitch cone. Bevel gears ...

A herringbone gear, a specific type of double helical gear, [1] is a side-to-side, rather than face-to-face, combination of two helical gears of opposite hands. [2] From the top, each helical groove of this gear looks like the letter V, and many together form a herringbone pattern (resembling the bones of a fish such as a herring).
