摘要 使用滚动轴承高速试验台和BRG 3000轴承力矩测量仪研究了填脂量对轴承温升、摩擦力矩和振动性能的影响。试验结果表明,高速工况下填脂量对轴承温升、摩擦力矩和振动的影响均呈非线性变化,中低速工况下填脂量与温升呈正相关关系。高速工况条件下存在一个填脂量值使轴承的温升、摩擦力矩和振动的综合性能最好,确定最佳填脂量时需在一定的温度范围内兼顾振动性能,本文中在给定高速工况条件下轴承填脂量为自由空间的15%时轴承综合性能最佳,且少于FAG超精密轴承样本中推荐的26%的填脂量。 The effects of grease filling amount on the temperature rise, friction torque and vibration performance of bearing were investigated on a high-speed rolling bearing test rig and the use of a BRG3000 bearing torque tester. Test results show that under high speed condition grease filling amount has non-linear relationship with bearing temperature rise, friction torque and vibration, unlike the positive relationship between the grease filling amount and temperature rise under middle and low speed condition. There exists an optimum grease filling amount that results in the best comprehensive performance of the bearing, including temperature rise, friction torque and vibration. Considering a lower temperature rise, the optimum value also results in a lower vibration. Under the given working condition the optimum value is 15% of the free volume, which is less than the 26% free volume recommended by FAG supper precision bearings catalog.
