According to the basic principle and calculation diagram of involute gear, the thickness of spiral teeth on any circle ly: In the formula θ， θ Y is expressed in radians, where: Basic parameters of involute gear: RB = mzcosa, r = MZ, RA = R + MHA, RF = R-M (HA + HF), where m is the module of involute gear, Z is the number of involute gear teeth, ha is the tooth height coefficient, HF is the tooth top coefficient, then the area of single tooth s tooth: As shown in Figure 2, it can be concluded that:
