Beveloid gears are used to accommodate a small shaft angle. The manufacturing technology used for beveloid gearing is a special setup of cylindrical gear cutting and grinding machines. A new development, the so-called Hypoloid gearing, addresses the desire of gear manufacturers for more freedoms. Hypoloid gear sets can realize shaft angles between zero and 20° and at the same time, allow a second shaft angle (or an offset) in space that provides the freedom to connect two points in space. The first application of Hypoloids is found in all-wheel-drive vehicles. Because of their unique geometry, Hypoloids can be used to connect the transfer case to the front axle without the use of CV joints, allowing for greater efficiency, reduced NVH characteristics and tighter packaging. The Hypoloid technology does not apply only to automotive drive trains. Its advantages apply also to aircraft as well as general gearbox manufacturing.
