Contact Model of Double Circular Arc Gear Based on Fractal Theory

Abstract

Aiming at the problem that it is difficult to solve contact strength calculation of double circular arc gear with the method of traditional the Hertz contact theory and FEM, methods of fractal theory had been used to establish the contact model of double arc gear based on fractal theory, and an example of calculation was given away. This article results that it is feasible to calculate contact strength with fractal theory in the driving of concave convex meshing gear and this contact model of double circular arc gear based on fractal theory would provide a new way of the research of contact strength calculation of double circular arc gear.
