A bevel gear is a type of gear that has a conical surface on one end. The cone shaped structure transmits torque between 2 non-parallel axes.

Depending on the helix angle used for particular applications and tasks, there are two further categories of bevel gears. The first one is straight bevel gears. As obvious by their name, they lack the helix angles. The second classification of a bevel gear is known as spiral bevel gears. There is another sub-classification of spiral bevel gears called zerol bevel gears but for the sake of description, we will use them as the same thing. Both of them have helix angles. As common as this is, only custom bevel gears Company US like Ami Gears can ensure that.

As technologies grow and industrialists and commercial users find other means to handle their applications, there remain only a handful of manufacturers who still manufacture straight bevel gears. Most only produce the spiral bevel ones but if you have a specific application that only a straight bevel gear could satisfy, there are manufacturers out there who might be able to help but you must carry out research as there is bound to be an apt and low-cost replacement for a straight bevel gear.

Furthermore, there are methods of manufacture that further divide the types of bevel gears available in the market. The first method is commonly known as the Gleason method while the second method of manufacture is usually referred to as the KlingenInberg method. The difference in these methods range from the shape of the gear's teeth. These days, the most commonly used method of manufacture of the bevel gears is the Gleason method. KlingenInberg method has fallen out of favor for a variety of reasons, the complexity of the process and lack of application maneuverability being not the least of them. As a custom bevel gears Company US, Ami Gears has helped dozens of customers build bevel gears.
