A New Method of Constructing Tooth Surface for Logarithmic Spiral Bevel Gear

Abstract

In this article it constructs tooth surface equation of a new type of bevel gear which is logarithmic spiral bevel gear by the tooth trace and the tooth profile curve with space geometric knowledge. By means of the CAD software which can intuitively understand the complex curves and surfaces and the MATLAB software platform, it makes the complex mathematical theory be easier to understand and apply correctly, and verifies the correctness of the tooth surface equations.
