摘　　要：齿轮上钻孔能够有效地降低齿轮传动的振动水平。针对某型直齿圆柱齿轮的有限元模型进行应力计算,将计算数据用响应面法和最小二乘原理拟合成二次多项式,再以最大应力最小化为目标进行优化求解,得到孔穴参数的设计值,并加工了齿轮样件;在齿轮封闭试验台上完成了孔穴齿轮与普通齿轮的对比试验。试验结果表明,孔穴结构可以降低齿轮副的振动,具有广阔的应用前景。Drilling on gears could reduce the vibration effectively.The finite element models of a pair of spur gears are studied for stress calculation.The stress data is fitted with quadratic polynomial by response surface method and least squares method.The design values of holes＇ parameters are presented through the optimization of minimizing the maximum stress.The gear samples are produced and the contrast test between holey spur gear and common spur gear is applied on the gear closed test bench.The test results imply that drilling on gears would damp the vibration of gear pair and can be applied extensively.
