高性能齿轮表面微观形貌及表面完整性设计制造基础研究

This proposal focuses on design and manufacture basic theories of gear tooth micro-topography and surface integrity. To propose and improve these basic theories is important from a scientific and engineering viewpoint, which can integrally synergize macro- and micro-topography, geometry-physical-material, design and manufacture. The key research contents are as follows. 1) The model and representation of gear tooth micro-topography and surface integrity under conditions of Ultrasound-assisted grinding. 2) The effects of manufacturing parameters on the gear tooth micro-topography and surface integrity are investigated and their quantitative relations with fatigue characteristic are analyzed. 3) The controllable generation method and parametric process of the gear tooth micro-topography and its integrity are developed. The main objectives of the project are to construct a basic theory and technology method of high-performance gear surface micro-topography and surface integrity quantitatively, by which a given surface micro-topography precision can be achieved. In China's conversion from gear manufacturing country to gear manufacturing power, the research proposal and its achievement can make a big difference.
