自润滑滑动轴承
自润滑轴承
自润轴承

In the present work , 40cr alloy steel was selected as the backing material , and ptfe composite was acted as a solid lubricant . the self - lubricating bearing was designed by an ansys software , and a solid lubricant embedded 40cr - ptfe bearing was prepared . it was expected to be effectively strengthened leading to long service life
本研究选择40cr为背衬与聚四氟乙烯( ptfe )复合材料为润滑剂,利用ansys有限元进行结构设计,制备出40cr - ptfe自润滑轴承,希望能够结合钢的高强度与ptfe的低摩擦,实现重载长寿命的目标。
