锥齿轮综合检验机主轴相交度误差检测与补偿方法研究

Research on Detection and Compensation Method for Main Spindle Axial Intersection Error of Bevel Gear testing Machine

随着航空等传动领域对锥齿轮传动振动性能及寿命可靠性需求的不断提升,对锥齿轮综合检验机的精度和功能要求进一步提高。轴线相交度是锥齿轮综合检验机的一项重要的精度指标,但现有的测量方法只能测量特定设备中轴线的相交度,不具有广泛适用性。本文研究提出了一种新的检测方法,用于评估检验机主轴相交度误差。该方法利用高精度检棒延伸轴线在空间相交,简化了测量过程。结合检验机的结构特点,计算出相交度误差的补偿方法,根据不同锥齿轮副轴交角计算对应的补偿量。这种补偿方法提高了检验机的测量准确性。补偿完成后,通过球头检棒验证补偿结果,进一步确保测量的可靠性。

With the continuous improvement in the requirements for vibration performance and reliability of bevel gear transmissions in aerospace and other propulsion fields,higher demands have been placed on the accuracy and functionality of bevel gear testing machines.Axial intersection is an important precision indicator of bevel gear testing machines,but existing measurement methods can only measure the axial intersection of specific equipment and lack broad applicability.This study proposes a new detection method for evaluating the error of the main spindle axial intersection of inspection machines.The method utilizes high-precision checking rods to extend the axial intersection in space,simplifying the measurement process.Combined with the structural characteristics of the inspection machine,a compensation method for axial intersection error is calculated,and corresponding compensation amounts are determined based on different angular positions of bevel gear pairs.This compensation method enhances the measurement accuracy of the inspection machine.After compensation is completed,the compensation results are validated using a ball head checking rod to further ensure the reliability of the measurements.
