计量泵蜗轮磨损分析及解决方法

Analysis and Solution of Worm Wheel Wear in Metering Pump

蜗轮传动作为计量泵中的重要传动机构,其传动效果会直接影响计量泵工作的平稳性。论文结合蜗轮传动的特性,阐述了蜗轮传动的失效形式以及引起这种现象的主要原因,提出了用飞刀加工蜗轮的方法来克服蜗轮磨损严重的情况,并严格按照啮合原理设计出理论飞刀齿形,得出的飞刀齿形各点坐标值,利用Matlab软件在数据方面的可视化将其转化为图像,为蜗轮制造精度及效率提供了新制有效的方法。

Worm gear drive as an important transmission mechanism in metering pump,its transmission effect will directly affect the stability of metering pump work. In this paper,combined with the characteristics of worm gear drive,This thesis expounds the worm gear transmission failure forms and the main cause of this phenomenon,with fly-cutter machining worm gear method is proposed to overcome the worm gear wear serious condition,and strictly according to the design of meshing principle theory tooth profile,fly-cutter teeth that shaped the coordinates of each point value,and then use Matlab software in data visualization of the transformation for the image. It provides a new effec-tive method for the manufacture precision and efficiency of worm gear.
