在滚动轴承中存在润滑脂并不意味着轴承就得到了合适的润滑。轴承运转一定时间后,润滑脂被“磨掉”,因此必须在一定时间内给轴承加润滑脂。这样的临界润滑应按时间表进行,不能盲目行事。本文介绍了有关润滑脂的作用,润滑脂的寿命和计算,以及怎样确定润滑周期等问题。 The presence of grease in the rolling bearings does not mean that the bearings are properly lubricated. Bearing a certain period of time, the grease is “worn away”, it must be within a certain period of time bearing grease. This critical lubrication should be carried out according to the schedule, can not act blindly. This article describes the role of grease, grease life and calculation, and how to determine the lubrication cycle and other issues.
