|Usage/Application||mounted on shafts|
|Material||cast irons,non ferrous material and non metallic materials|
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. The pitch surface of bevel gears is a cone.The various materials used for gears include a wide variety of cast irons, non ferrous material and non – metallic materials. The selection of the gear material depends upon:
Type of workPeripheral speedDegree of accuracy requiredMethod of manufactureRequired dimensions and weight of the driveAllowable stressShock resistanceWear resistance.Some materials chosen include:
Cast iron, which is popular due to its good wearing properties, excellent machinability and ease of producing complicated shapes by the casting method. It is suitable where large gears of complicated shapes are needed.Steel, which is sufficiently strong & highly resistant to wear by abrasion.Cast steel, which is used where stress on the gear is high and it is difficult to fabricate the gears.Plain carbon steels, which find application for industrial gears where high toughness combined with high strength.Alloy steels, which are used where high tooth strength and low tooth wear are required.Aluminum, which is used where low inertia of rotating mass is desired.Gears made of non–metallic materials give noiseless operation at high peripheral speeds.Advantages :
This gear makes it possible to change the operating angle.Differing of the number of teeth (effectively diameter) on each wheel allows mechanical advantage to be changed. By increasing or decreasing the ratio of teeth between the drive and driven wheels one may change the ratio of rotations between the two, meaning that the rotational drive and torque of the second wheel can be changed in relation to the first, with speed increasing and torque decreasing, or speed decreasing and torque increasing.
