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