【摘要】：H型动压气体轴承陀螺电机(以下简称"动压电机")装配后的组合间隙是轴承筛选的关键指标。实际工程中部分动压电机产品的组合间隙与按照轴承零件尺寸计算的间隙相差较大,测量重复性差,合格率较低。为了进一步提高动压电机的一致性和合格率,首先从轴承间隙的测量方法入手,对轴承间隙测量误差建立模型树进行分析,找出了轴承零件尺寸稳定性、多余物以及间隙测量工装是影响轴承间隙测量误差的主要因素,提出了增加稳定处理,优化间隙测量工装,抑制电机污染源,组合清洗等技术改进措施,并通过合理调整间隙控制指标,显著提高了动压电机一致性和合格率。这些思路方法都为动压电机生产量化控制和可靠性筛选提供了很好的借鉴参考价值。
[Abstract]:The combined clearance of H type hydrodynamic gas bearing gyroscope motor (hereinafter referred to as "hydrodynamic motor") is the key index of bearing screening. In actual engineering, the combined clearance of some hydrodynamic motor products differs greatly from the gap calculated according to the size of bearing parts, the repeatability of measurement is poor, and the qualification rate is low. In order to further improve the consistency and qualification rate of hydrodynamic motor, starting with the measuring method of bearing clearance, the model tree of bearing clearance measurement error is analyzed, and the dimensional stability of bearing parts is found out. Superfluous material and gap measuring tool are the main factors that influence the error of bearing clearance measurement. The technical improvement measures such as increasing stability treatment, optimizing gap measuring tool, restraining the pollution source of motor, combined cleaning and so on are put forward. By adjusting the clearance control index reasonably, the consistency and qualified rate of hydrodynamic motor are improved significantly. These ideas and methods provide a good reference value for the quantization control and reliability screening of hydrodynamic motor production.
