Beveloid gears are used to accommodate a small shaft angle. Themanufacturing technology used for beveloid gearing is a special setup of cylindrical gear cutting and grinding machines. A newdevelopment, called Hypoloid gearing, addresses the desire of gearmanufacturers for more freedom in shaft angles. Hypoloid gear setscan realize shaft angles between zero and 20° and at the same timeallow a second shaft angle (or an offset) in space which providesthe freedom to connect two points in space. In all wheel drivenvehicles that traditionally use a transfer case with apinion/idler/gear arrangement or a chain, the exit of the transfercase needs to be connected with the front axle. This connectionnecessitates the use of two CV joints, because the front axle inputpoint has a vertical offset and is shifted sideways with respect tothe transfer case exit. Compared to a single CV joint, the two CVconnections are more costly and less efficient. However, the newlydeveloped Hypoloids can remedy the situation by offering morefreedom in shaft angle and additional offset which eliminates theneed for an additional CV joint. Moreover, the Hypoloid technologyoffers enhanced performance compared to beveloids with straightteeth. In addition to the automotive drive trains, Hypoloidtechnology can be applied to aircraft as well as general gearboxmanufacturing.
