摘　　要：采用指状砂轮磨削等速万向节钟形壳椭圆沟道的理论误差在4μm左右,为减小理论误差,提出了一种用盆状砂轮来磨削等速万向节椭圆沟道的新方法。因避免了指状砂轮头部的干涉,其参数优化的有效性和精确性得到了提高,能最大限度地保证加工截面的形状和精度。建立了盆状砂轮加工的数学模型,采用约束随机方向法对砂轮的参数进行了优化,对其加工原理进行了详细的理论研究,并对加工误差进行了分析。仿真结果表明,用盆状砂轮磨削的椭圆沟道的理论误差可减小到1μm。The theoretical error of outer race elliptic track in ball basket constant velocity joint ground by finger--like grinding wheel is about 4μm. In order to decrease the error, a new grinding method with basin--like grinding wheel was proposed herein. When the design parameters were optimized,the basin--like grinding wheel will avoid the problems that the feasibility and grinding accuracy were restricted by the interference of the head in the grinding process by means of finger-- like grinding wheel, and can be used to ensure the machining precision and the sectional shape of the raceway to the greatest extent. Aiming at the grinding process with basin--like grinding wheel, the paper established the mathematical model, optimized the parameters by using restrictive random direction method, studied the processing principle in detail, and analyzed the machining errors. The simulation results indicate that the theoretical error of elliptical groove ground by basin--like wheel will be reduced to the level of 1 μm.
