How to understand the gear involute equation of proe r = 36 theta = t * 45 x = R * cos (theta) + R * sin (theta) * theta * pi / 180 y = R * sin (th)

How to understand the gear involute equation of proe r = 36 theta = t * 45 x = R * cos (theta) + R * sin (theta) * theta * pi / 180 y = R * sin (th)

The Descartes equation of involute, you know, there are only two variables: the radius of base circle and the angle of development. If you write r = 36 in PROE, proe will automatically define the variable r value as 36. You can write the name of the variable as you like. The following theta is the same. You can also write a. t is the built-in function of PROE, and the operation will be from 0 to 1
