Summary of Expertise: Listed with other top experts in: 
Expert is an expert with over twenty-five years of experience in research, development, and design of mechanical motion and power transmission. He is the developer of a gear design method and software. This method allows him to significantly maximize gear transmission technical and market performance including: increased load capacity; reduced size and weight; higher efficiency; lower noise and vibration; increased reliability and lifetime; reduced cost, and more. Expert is the author of a unique methodology for the design of gears with asymmetric tooth profiles that provides additional performance enhancement for gear drives with unidirectional load transmission. He applies the Finite Element Method (FEM) for stress analysis of gears resulting in accurate bending and contact stress definition for load sharing calculations.
