比较了润滑脂耐高温性能的静态和动态试验方法,说明润滑脂的耐高温性能应该采用动态试验方法,以试验后润滑脂润滑功能的劣化程度即轴承摩擦力矩的升高程度或手感的加重程度来评价,强调试验后润滑脂色变与否及色变程度与其润滑功能没有必然联系,不宜作为润滑脂耐高温性能的评价依据。 The static and dynamic test methods of the high temperature grease performance are compared. It is suggested that the dynamic test method should be adopted for the high temperature performance of the grease. After the test, the degree of deterioration of the grease lubrication function is the degree of increase of the bearing friction torque or the aggravation of the hand feel To evaluate, emphasizing the test whether the grease discoloration or not and the degree of discoloration is not necessarily linked with its lubricating function, should not be used as a basis for evaluating the high temperature performance of grease.
