What is the definition of the thickness of the base circle of spiral bevel gears?
Reply to hyfjy post, old fee hello! The three circles (the top circle, the round circle, the base circle) and the two spherical involute lines I show are all on a spherical surface.
On the basis of the plane gear of the equivalent gear, the thickness of the circular arc tooth of the equivalent gear can be calculated, and then the thickness of the base arc tooth is calculated by the formula. The thickness of the gear tooth is known, and the base tooth thickness is the center angle of the base tooth thickness, that is, the tooth thickness is divided by the radius of the base circle.
Reply to woodee post I think it is the analysis of spherical involute circular tooth indexing, thickness and base arc tooth thickness should be measured in the circular section, is also in a "section", must make in the "circle" section, that is to say, the first arc measurement the end and the center line of the intersection circle is two radius made with two spherical involute package is spherical for arc. This should be a theoretical discussion, so it is true to use the spherical involute to analyze the parts of the bevel gear. This is what one of my previous teachers told us, not the intersection of the sphere on the sphere and the involute of the two spheres, which are parallel to the base plane of the base cone. To extend it, for the vertical perpendicular to the two radii, the requirements of the circular arc tooth thickness angle to the vertical line is the intersection of the dihedral angle between two planes each with a radius and vertical line composition, which is the angle between the two radius, the angle and the other an angle is different, close, but not the same thing.
