bevel gears are used in differential drives, which can transmit power to two axles spinning at different speeds, such as those on a cornering automobile.
bevel gears are used as the main mechanism for a hand drill. as the handle of the drill is turned in a vertical direction, the bevel gears change the rotation of the chuck to a horizontal rotation. the bevel gears in a hand drill have the added advantage of increasing the speed of rotation of the chuck and this makes it possible to drill a range of materials.
the gears in a bevel gear planer permit minor adjustment during assembly and allow for some displacement due to deflection under operating loads without concentrating the load on the end of the tooth.
spiral bevel gears are important components on rotorcraft drive systems. these components are required to operate at high speeds, high loads, and for a large number of load cycles. in this application, spiral bevel gears are used to redirect the shaft from the horizontal gas turbine engine to the vertical rotor. bevel gears are also used as speed reducers
