8. Basic parameters and expression of tooth profile: Bb%hwfu,b-r0 According to the standard gear design rules, as shown in Figure 2 groove Contour calculation reference diagram. +e "A[|B0
9. Basic parameter diagram:
10. Modulus and number of teeth are the most important parameters of gears. In the case of constant number of teeth, the larger the modulus, the larger the gear teeth, the stronger the ability to resist breakage, of course, the larger the gear wheel billet, the larger the space size; In the case of constant modulus, the larger the number of teeth, the more gentle the involute, the thicker the tooth top round teeth, the thickness of the tooth root round teeth correspondingly thicker.
