【摘要】：圓柱滾子軸承常用于冶金機(jī)械等領(lǐng)域超高負(fù)載和中等轉(zhuǎn)速的設(shè)備中,其運(yùn)轉(zhuǎn)狀態(tài)直接決定著現(xiàn)場(chǎng)生產(chǎn)的安全與否。提出在現(xiàn)場(chǎng)實(shí)測(cè)關(guān)鍵零部件應(yīng)力水平的基礎(chǔ)上,運(yùn)用理論計(jì)算和有限元仿真技術(shù)相結(jié)合的方法,分別得出圓柱滾子軸承外部機(jī)械載荷和內(nèi)部熱載荷作用下滾子與套圈之間的接觸應(yīng)力,以此評(píng)估軸承的工作狀態(tài)。將某煉鋼廠擺剪減速機(jī)軸承作為案例進(jìn)行了分析,分析結(jié)果與現(xiàn)場(chǎng)實(shí)際相吻合,表明上述分析方法的可行性。分析方法為相關(guān)技術(shù)人員進(jìn)行圓柱滾子軸承工作狀態(tài)的評(píng)估提供了技術(shù)路線。
[Abstract]:Cylindrical roller bearings are often used in ultra-high load and medium rotating speed equipments in metallurgical machinery and other fields, whose running state directly determines the safety or not of field production.Based on the field measurement of the stress level of key parts, the method of combining theoretical calculation with finite element simulation technology is proposed.The contact stress between the roller and the ring under the action of the external mechanical load and the internal thermal load is obtained respectively to evaluate the working state of the bearing.The bearing of pendulum shear reducer in a steelmaking plant is analyzed as a case, and the results are in agreement with the actual situation, which indicates the feasibility of the above analysis method.The analytical method provides a technical route for the related technicians to evaluate the working status of cylindrical roller bearings.
