Gear ratio of bevel gears isnumber of ring gear teeth divided by number of pinion gear teeth.
It is called a gear tooth. There can be many types of teeth based on the gear design; such as spur, helical, straight bevel, spiral bevel, hypoid, and several others.

What is the speed ratio of an input with 36 teeth meshed to a gear with 20 teet?
The best way is to count the teeth on the ring gear and divide by the number of teeth on the pinion gear. Or you can count the number of turns of the pinion it takes to get one full turn of the ring gear. For example, if we divide a ring gear with 41 teeth by a pinion gear with 10 teeth we find that the gear ratio is 4.10:1 (41/10 = 4.10).
The engineer that designs the gearbox. The sizes of the bull gear and pinion gear(s), as well as any idler gear(s) are dependent upon the sizes of the drive and driven shafts and the torque that will be applied to each, as well as the ratio of gear reduction, and speed of rotation.

a bevel gear assembly.
An example of a bevel gear is a hand drill.
bevel gear is driven by a ring gear thus turning the axles
A bevel gear can change the direction of the driven shaft/axle by 90 degrees. If different tooth counts are used, bevel gears can also change the ratio between speed/strength of the turning motion.
hypoid bevel, spiral bevel and straight bevel
A bevel gear provides torque and rotation at 90 degrees, and a helical gear provides it at 180 degrees.
Hypoid gear, Spiral bevel gear, straight bevel
Hypoid bevel
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.
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.
