Information

According to the geometrical relationship, the intersection line between the normal plane and the indexing cylindrical surface at a point on the helical cylindrical gear tooth line is an ellipse. The radius of curvature of the ellipse is taken as the dividing circle radius of a hypothetical spur gear, and the normal modulus and normal tooth angle of the helical gear are taken as the modulus and tooth angle of the hypothetical spur gear. The hypothetical spur gear is called the equivalent gear of the helical spur gear. The so-called equivalent number of teeth of helical cylindrical gear refers to the equivalent number of teeth of helical cylindrical gear.
