机械压力机球头螺杆烧伤的问题分析及解决方案

Problem analysis and solving method of burned ball screw for mechanical press

曲柄滑块机构是机械压力机的重要部分,而滑块上的球头螺杆的螺纹及球头在工作时因反复受到挤压力、摩擦力以及频繁承受较大的冲击力,容易产生烧伤现象。本文通过摩擦学原理相关知识判断故障产生原因,通过分析故障原因提出相关解决方案。

The reason for failure has been judged in the text on the basis of the theory of tribologieal prin- ciple. The related solving project has been put forward by analysis of failure reason.
