进口TM35V双螺杆挤出机输出齿轮轴的修复设计

DESIGN FOR REPAIRING EXPORT GEAR-SHAFT FOR TWIN-SCREW EXTRUDER OF TM 35V

TM35V双螺杆挤出机系扬子石化公司研究院于1987年从意大利MARIS公司引进。该机长输出齿轮轴于1991年4月断裂。本文对事故原因进行了分析,对选材、参数、加工工艺作了推敲与计算,提出了保证新齿轮轴安全使用的一些措施与建议。

The rwin-screw extruder of TM 35 V was imported from Marls Co. of Italy by Research Insti-tute of Yangzi Petrochemical Corp. in 1987,the long export-shaft was broken in April 1991. Thebreakdown reason was analysed in this paper.Selection of the material parameters and technologicalrequirements have been deliberated and counted. A number of disadvantages have been suitablediscussed, some measures and proposition about safe use for new gear-shaft were presented.
