How Are Bevel Gears Manufactured?

February 17, 2023

Bevel gears are an essential component of many machines, from car and truck engines to wind turbines and more. It is a type of curved gear with teeth that allows for meshing between two perpendicular rotating shafts. Its distinct shape and design make it highly efficient at transferring motion from one shaft to the other. But how exactly are these gears manufactured? In this blog post, we will explore the different methods used to make bevel gears.

How are bevel gears manufactured?

They are manufactured by first cutting a cone-shaped piece out of a larger piece of metal. This cone is then cut in half to create two bevel-shaped gears. These gears are then put together so that they mesh with each other and rotate smoothly. The teeth of the gears can be cut in a variety of ways, including milling, hobbing, shaping, and grinding. The material used to make these gears can vary greatly depending on the application and can range from steel to plastic.

Applications of bevel gears

They are commonly used in drivetrains for cars, trucks, and motorcycles. The gears are used to change the direction of the rotational force being applied to the shaft. Bevel gears can also be found in differentials and final drives. 


They are also used in marine applications such as in the steering systems of boats and ships. They are also used in transmissions for wind turbines to convert the rotational force of the rotor into linear motion. In addition, bevel gears can be found in construction equipment, conveyor systems, printing presses, and pumps.


Bevel gears are an important component in many machines and can be manufactured in a number of ways. The most popular methods involve cutting the gear teeth with hobbing, shaping, or broaching tools, but they can also be milled or die-cast depending on the required application. Each method has its own advantages and disadvantages that must be weighed before deciding which method is best for your specific applications.
