Gear Cutting

Reference work entry



Gears are used in many applications and geometries. The geometry reaches from gears with only a few millimeters of diameters until large gears with diameters of several meters. Most power gears for the automotive and high-performance industry sector are manufactured by cutting. Further manufacturing technologies are casting, powder metallurgy, and forming. The most common gear types for such applications are cylindrical and bevel gears. The general geometry elements of gears are manufactured by conventional technologies like turning and grinding. But for manufacturing of the tooth gap, gear-specific manufacturing technologies are used. This is caused due to the complex geometry and high requirements on the manufacturing accuracy of gears.

Figure 1shows the two general gear cutting technologies:...
