为建立超精密磨齿工艺的科学原理与技术框架, 以研制ISO 1328-1∶1995中1级精度的基准标准齿轮为目标, 研究了超精密齿轮磨齿工艺原理与方法。首先, 依据渐开线齿轮最佳成型原理, 考虑机床关键元部件易精化及结构刚度高的特点, 选择Y7125型大平面砂轮磨齿机为工具机。然后, 从齿坯工艺与基准修复、机床参数的优化调整及科学的磨齿操作等方面对超精密磨齿工艺进行了探讨与研究。最后, 通过磨齿实验研制出了m2和m4一级精度的基准标准齿轮。该项工艺的研究对我国齿轮制造技术与水平的全面提升具有指导作用。

To establish the scientific principles and technical frameworks of the ultra-precision grinding technology, the research work was performed on the processing principles and methods of the ultra-precision gear-grinding to develop the ultra-precision master gears with class 1(ISO 1328-1: 1995). Firstly, according to the optimal forming of an involute and the easy refinement and high structural rigidity of the machine, the gear grinder with flat-faced wheel Y7125 was chosen as the object machine tool. Then the ultra-precision gear-grinding processing was discussed and studied from the aspects of gear blank processing and datum renovation, optimal adjustment of grinder parameters and scientific gear-grinding operation. Finally, the medium module (m2 and m4) ultra-precision master gears with class 1 were developed by a scientific gear-grinding experiment. The research on ultra-precision gear-grinding processing plays a guiding role in the overall improvement of gear manufacturing technology in China.
