摘　　要：为降低低速重载滑动轴承的摩擦振动噪声,对滑动轴承的材料、润滑槽及润滑脂进行了改进,并对原有轴承副及改进后的轴承副进行摩擦性能试验。结果表明:新型润滑脂有利于降低滑动轴承的临界爬行角速度;直槽结构的滑动轴承摩擦力矩和临界角速度均小于斜槽结构;直槽MGB轴承具有较好的抗摩擦振动性能。To reduce the frictional vibration and noise of sliding bearings under low speed and heavy load conditions, the materials, lubricating groove and lubricating grease of sliding bearings are improved. The friction properties of the original and improved bearing pair are experimented. The results show that the new type lubricating grease is benefit to reduce the critical crawling angular velocity of sliding bearings. The friction moment and critical angular velocity of slid- ing bearings with straight groove strueture are smaller than bearings with skewed groove structure. The MGB bearings with straight groove have better frictional vibration resistance.
