参数：- No_Of_Teeth - 32 Normal_Module - 2.8 Pitch_Diameter - 100 Normal_Pressure_Angle - 20 Helix_Angle - 26 宽度 - 25

斜齿轮公式：- Transverse_module = normal_module / cos (helix_angle) Normal_circular_pitch = pi * normal_module Transverse_circular_pitch = pi *transverse_module Transverse_pressure_angle = atan((tan (normal_pressure_angle))/(cos (helix_angle))) Outer_Diameter = pitch_diameter + (2 * normal_module) Root_diameter = pitch_diameter - (2 * 1.25 * normal_module) Base_diameter = pitch_diameter * cos (transverse_pressure_angle) Normal_tooth_thickness = (pi *transverse_module) / 2 Lead = pi * Pitch_diameter / tan (Helix_angle)

渐开线曲线方程（笛卡尔坐标）：- Base_radius = Base_diameter / 2 角度 = t*90 Cir_len = (PI * Base_radius * t ) / 2 X_PNT = Base_radius * cos（角度） Y_PNT = Base_radius * sin（角度） x = X_PNT + ( Cir_len * sin(Angle)) y = Y_PNT - ( Cir_len * cos(Angle)) z = 0
