Analysis and Experiment on Tribological Performance of Vein-Bionic Textured Cylindrical Roller Thrust Bearing
In order to study the influence of bionic vein texture on friction and wear performance of cylindrical roller thrust bear-ing,the finite element model of cylindrical roller thrust bearing was established by ANSYS Workbench,and the real physical state of untextured and textured cylindrical roller thrust bearing under test conditions was analyzed by transient dynamics,which was verified by test.The vein-shaped bionic texture samples were prepared by laser surface texturing technique,and were tested by MMW-1A vertical universal friction and wear tester.The simulation and test results show that,compared with the non-textured bearing,the rising inflection point of the friction coefficient of the vein-shaped bionic textured bearing is obviously prolonged,and the wear rates of the shaft ring,cage and seat ring are reduced by 96.92%,96.74% and98.92%,respectively,which signifi-cantly improves the wear resistance of the bearing,which is consistent with the simulation results.This laid a foundation for the theoretical research of bionic texture design of vein shape.
