a bevel gear assembly.
bevel gear is driven by a ring gear thus turning the axles
Gear ratio of bevel gears isnumber of ring gear teeth divided by number of pinion gear teeth.
hypoid bevel, spiral bevel and straight bevel
Gear ratio of bevel gears isnumber of ring gear teeth divided by number of pinion gear teeth.
A bevel gear provides torque and rotation at 90 degrees, and a helical gear provides it at 180 degrees.

Workers use bevel gear in the industry of locomotives. The use of bevel gears is used in numerous industrial applications. You can manufacture bevel gears for multiple uses in many situations such as maintaining a power plant.
If both gears designed and manufactured correctly, spiralbevel gear is stronger compare to a straight bevel gear. Spiral bevel gear is also quieter. For example, in mineral processing industry, spiral bevel gears are used in rock crashers because of the higher endurance. When the tooth is spiral (helical) it becomes possible to increase the size of the gear tooth without reduction of the contact ratio. The larger tooth is stronger compare to a smaller tooth. The reason why straight bevel gears are still used is because spiral bevel gears are more expensive in design and manufacturing, thanks to use of expensive spiralbevel gear cutting machines from Gleason Works or from Klingelnberg AG. In 1990, it became possible to manufacture spiral bevel gears on universal CNC milling machines, because of the development of special spiralbevel software for 3d CAD gear tooth modeling. Today, thanks to spiralbevel software, both straight and spiral bevel gears are manufactured on CNC milling machines at the same low cost.
