Computer Aided Solid Modeling about Ellipse Gear

Using curvature radius of tooth shape center on ellipse gear pitch curve as equivalent gear pitch circle radius,column gear design method was used to set up ellipse gear equation.By design VC program and input tooth,modulus,eccentricity to realize automatic calculate ellipse gear's other parameters,tooth outline coordinate and show the outline shape,as well as output ibl file needed for Pro/E solid modeling,by using powerful function Pro/E to complete solid modeling of ellipse gear.
