摘要: 测量非圆齿轮时存在坐标系误差与加工误差相互耦合、噪声点多和测量效率低等问题.为了检测齿面真实情况,需对理论齿面进行测量规划并建立测量坐标系.基于此,根据测量坐标系与设计坐标系之间的关系建立数学模型,并对其进行优化和求解.同时,针对测量点与理论点之间的关系建立数学模型,分析测量误差对检测结果的影响并进行补偿.进而,通过三坐标测量机误差检测实验验证该方法的正确性.结果表明,该方法的网格畸变程度比常规方法和无约束方法分别降低了15.6%和6.6%.由此说明该方法是正确有效的.

Abstract: When measuring non-circular gears, it will encounter problems such as mutual coupling of coordinate system error and processing error, many noise points, low measurement efficiency, etc. In order to detect the true condition of the tooth surface, it is necessary to plan measurements of the theoretical tooth surface and to establish a measuring coordinate system. Accordingly, a mathematical model is established based on the relationship between the measurement coordinate system and design coordinate system, which is optimized and solved. At the same time, a mathematical model is established for the relationship between the measurement point and the theoretical point. It also analyses the effect of measurement error on the detection results and compensates the measurement error. Further, the accuracy of this error detection method is verified by coordinate measuring machine error detection experiments. The results show that the degree of mesh distortion of this method is reduced by 15.6% and 6.6% compared to the conventional and unconstrained methods, respectively, thus indicating its correctness and effectiveness.

Key words: non-circular gear, coordinate measuring machine, tooth surface error, measuring coordinate system, error compensation
