【摘要】 为了开发新型免维护高性能带式运输链托辊,文中分析了炼铁厂托辊的运行工况,并基于该工况,分析了满足该工况条件下的托辊自润滑滑动轴承材料PV值范围;试验研究了所采用的新型自润滑轴承的摩擦学性能;并将采用该轴承制备出的托辊应用在现场中进行了长寿命考核;运行结果证实了该新型自润滑轴承和托辊的长寿命和工作可靠性。更多还原

【Abstract】 A new type of high-capability tape transporter which needs nomaintenances is introduced in the paper. At first running condi-tion of carrier roller in puddling plant is analyzed. Based on it, the PV value range of the material to be used in self-lubricatedbearing of carrier roller is calculated. Tribology performance ofthis new self-lubricated bearing was tested. And this bearing ap-plied in carrier roller in-site is assessed for its long life. The re-sult verified that this new self-lubricated bearing and carrier rollerlong life and reliability.更多还原
