A quantitative calculation approach research of tooth surface friction characteristic parameters

Abstract

Abstract:A new calculation approach of tooth surface friction characteristic parameters is raised in this paper, the caclulation approach is based on gear drive test experience and finite element multi field coupling analysis method and technology.In the process of solution, friction characteristic concept of engineering oriented complex gear drive is raised, "experiment-calculation composite model" is built, tooth surface friction characteristic parameters(friction coefficients) are inversely analyzed by the composite model under different lubrication conditions. The problem of complicated tooth friction coefficients is solved. The calculation method is a new idea on solving friction characteristic parameters under complex lubrication conditions, it unites theoretical research, system modeling, numerical simulation and experimental test, so its solution is more reasonable. Exactly research friction coefficients can help to search gear friction principle and to upgrade the level of decrease noise and vibration of gear.
