一种牵引杆球铰椭圆度的改善方法

摘要

The influence of cold and hot extrusion, conditioning time after hot extrusion, and secondary cure on the ellipticity of traction link bush was investigated. The results showed that the ellipticity was improved by hot extrusion, conditioning after hot extrusion and secondary cure. Longer conditioning time after hot extrusion led to better modification result,and the effect of secondary cure was the most significant.%研究冷热挤压、热挤压后停放时间和二次硫化对牵引杆球铰椭圆度的影响.结果表明,热挤压、热挤压后停放和二次硫化对产品椭圆度有改善作用,并且热挤压后停放时间越长,改善作用越大,而二次硫化的改善作用最为明显.
