摘　　要：利用飞秒激光刻蚀技术在滚动轴承内圈沟道中心两侧制备了梳齿型沟槽阵列,在限量供油条件下,利用滚动轴承摩擦力矩测量仪测量了轴承的摩擦力矩及温升。结果表明:带有梳齿沟槽阵列表面的轴承摩擦力矩、外圈温升以及沟道磨损状态均得到改善;限量供油条件下,轴承摩擦力矩降低率随着载荷增加而降低,外圈温升得到有效抑制。利用光干涉弹流润滑油膜测量仪在限量供油条件下测量梳齿沟槽阵列表面润滑油膜厚度的结果,验证了该表面对滚动轴承具有润滑增效的作用。The comb-tooth groove arrays are prepared on both sides of inner ring raceway center of rolling bearings by femtosecond laser etching technology.The friction torque and temperature rise of the bearings are measured by friction torque measuring instrument under limited oil supply condition.The results show that the friction torque,temperature rise of outer ring and wear state of raceway of the bearings with comb-tooth groove array surfaces are improved;under limited oil supply condition,the reduction rate of friction torque of the bearings decreases with the increase of load,and the temperature rise of outer ring is effectively suppressed.The results of measuring the lubricating oil film thickness on comb-tooth groove array surfaces under limited oil supply condition by using optical interference elastohydrodynamic lubricating oil film measuring instrument verify that the surfaces have lubrication enhancement effect on rolling bearings.
