What are the standard modulus of a straight bevel gear on which circle?
The standard modulus is specified on this scale and conforms to the calculation method of the spur gear. The top of the tooth and the height of the root are measured on the back cone.
The standard modulus of a straight bevel gear is specified on the back cone (the big end). The pitch cone (also called the sub cone) is perpendicular to the back cone, and the circle generated by the intersection is the dividing circle of the straight bevel gear;
