摘要
Abstract
In order to solve the local wear problem of crankshaft in higher motor thickness and smaller crankshaft diameter rolling rotor compressors,through coupled simulations of friction dynamics and fluid dynamics,the impact on the lubrication oil film thickness of the shaft system was analyzed.Besides,the optimal mounting position of PTFE bushing on main bearings was determined.The improvement of PTFE bushings on the load pressure and oil film lubrication of main bearings was analyzed.The performance,noise and durability tests were carried out to verify the effectiveness and feasibility of PTFE bushings for the improvement of crankshaft lubrication of high motor thickness and small-diameter compressors,provided design solutions and experimental basis for addressing the problem of crankshaft wear in rolling rotor compressors.关键词
