| 渐开线的复杂性与加工、测试中的特殊性一直是渐开线样板制造技术中的瓶颈．为研制高等级渐开线样板,首先探讨了渐开线的成型原理,指出滚轮-导轨式机械展成机构具有渐开线一次成型、驱动精度不影响渐开线的展成精度、误差来源少的优点,适合加工高等级渐开线样板．然后根据渐开线的生成原理,设计了双滚轮-双导轨式渐开线样板测量与磨削装置．最后对一渐开线凸轮试件进行了精密磨削实验,精密测试表明,该渐开线凸轮试件在105 mm的展成长度内渐开面的齿廓总偏差不超过0.6 μm,齿廓形状偏差不超过0.4 μm．实验结果表明,双滚轮-双导轨式渐开线样板磨削与测量装置符合渐开线的成型原理,具备加工与测量高等级渐开线样板的能力． |

| The complexity and specificity of involute processing and test have been the bottleneck of manufacturing technique for involute artifact. In order to develop high-grade involute artifact, the forming principle of the involute is discussed, and it is pointed out that the wheel-rail type of mechanical generating mechanism which forms the involute by one-time method and has no effects of driving accuracy on generating accuracy and has less error source is suitable for processing the high-grade involute artifact. Then, the double-wheel-rail type of grinding and testing devices for the involute artifact is designed according to the forming principle of the involute. Finally, a precision grinding experiment for an involute cam is conducted. The testing results show that the total profile deviation is not more than 0.6 μm and the profile form deviation is not more than 0.4 μm in 105 mm generating length of the involute cam. The experimental results show that the double-wheel-rail type of mechanical generating mechanism matches with the forming principle of the involute and has the capability of processing and measuring high-grade involute artifact. |
