WebGear teeth are designed with the unique profile and it’s called an involute profile. The involute profile is made by taking a string and wrapping it around a cylinder. We then trace the curve of the end of the string as it unwinds. As you can see, a curve with a constantly increasing radius is made. WebMar 4, 2024 · For 20° gears, have more than 16 teeth, or be prepared to learn a lot of advanced geometry; Tooth length is largely independent of the pressure angle or involute. By convention: gear teeth stick out one modulus above the pitch circle (there are variations). gear teeth extend to one modulus below the pitch circle (there are variations).
