As shown in the figure, the coordinate system Sa of the large wheel surface cone of spiral bevel gear is established, and the large wheel coordinate system S2 is established at the intersection point O2. After the design of the large wheel blank of spiral bevel gear is completed, its structural parameters are known.
In the coordinate system SA, the cone equation of the large wheel surface of spiral bevel gear is:
Where:
(V, J) – determine the parameters of the moving point m on the face cone
δ A — bevel angle of spiral bevel gear surface
In the figure:
Za — distance from cone apex of spiral bevel gear face to staggered point
B – width of large tooth surface of spiral bevel gear
