按润滑材料的品种,滚动轴承的润滑可分为润滑油润滑和润滑脂润滑。一般来说,润滑油的流动性好,能充分润滑轴承的运转部位,减少运转阻力,避免引起轴承温升。因此,它的润滑效果好,这对高速运转的轴承尤为重要。但是它对于机械的密封性能要求高。润滑脂的流动性差,不能自动补足到润滑部位,所以它的润滑效果不如润滑油好,但对机械部件的密封防漏要求低。对于工程机械、汽车等转速要 According to the types of lubricating materials, the lubrication of rolling bearings can be divided into lubricating oil and grease lubrication. In general, the lubricating oil has good fluidity, can fully lubricate the running part of the bearing, reduce the running resistance, and avoid causing the temperature rise of the bearing. Therefore, it has a good lubricating effect, which is particularly important for high-speed bearings. However, it requires high mechanical sealing performance. The grease has poor fluidity and cannot be automatically replenished to the lubrication area. Therefore, its lubrication effect is not as good as that of the lubricating oil, but its sealing and leakage prevention requirements for mechanical components are low. For construction machinery, automobiles and other speed
