摘要
轴承润滑脂的应用使摩擦副表面形成一层薄薄的油膜,防止滚动体与滚道两者间直接接触,从而减少轴承内部摩擦、磨损及发热,防止烧粘,同时还具有密封及防止轴承被锈蚀腐蚀的作用。因此,轴承润滑脂选型至关重要,不仅要考虑轴承的工作温度、转速、载荷等要求,还要考虑润滑脂的初始填充量和使用寿命等因素。本文主要对润滑脂的作用及机理、润滑脂选择要点、使用寿命等方面进行总结分析,且列举两个型号轴承进行计算验证,期望为轴承行业润滑脂的应用与选型提供参考与借鉴。
The application of the bearing grease forms a thin oil film on the surface of the friction pair to prevent direct contact between the roller and the raceway,thus reducing the internal friction,wear and heat of the bearing,preventing burning and sticking,as well as sealing and preventing the bearing from being corrosed by rust.So bearing grease selection is extremely important,not only to consider the operating temperature,speed,load and other requirements of the bearing,but also to consider the factors such as initial filling amount of the grease and service life.This paper mainly summarizes and analyzes the function and mechanism of the grease,selection points of the grease and service life,and lists two types of bearings for calculation and verification,so as to provide references for the application and selection of the grease in the bearing industry.
