熔体计量泵传动轴头断裂原因分析及改进

Causes Analysis and Improvement of the Driving Shaft Head Broken of Spinning Pump

针对长丝纺丝机高精度标准件——计量泵的传动轴头的断裂现象进行了原因分析、强度计算,通过理论分析和计算得出轴头断裂的主要原因是强度不够。为了满足现场需要,提出改进轴头设计结构和进行合适的热处理并用的工艺制造方法,使计量泵传动系统能够精确、安全、可靠的运行。

The causes analysis of driving shaft head broken of spinning pump and strength calculation of the shaft head are carried out. After theoretic analysis and calculation, the main reason of the shaft head broken is not enough strength. In order to meet the requirements of the user, the improvement of shaft head design and suitable heat treatment are put forward enabling driving system of the spinning pump exact, safe and reliable operation.
