现在国外对密封的齿轮和蜗轮传动装置,广泛使用半流体润滑脂,这种脂的状态介于液体润滑油和塑性润滑脂之间。半流体润滑脂是由分散介质和分散相(稠化剂)组成的,这与塑性润滑脂相似。但是,由于稠化剂含量较少,在没有任何外加负荷时,受本身重量的作用,半流体润滑脂的流动又与润滑油相似。半流体润滑脂的特性决定了它比液体传动润滑油具有一系列优点。例如,在减速器中使用半流体润滑脂,可节省复杂和贵重的密封费用,大大降低润滑脂的消耗和简化设
Now abroad for the sealed gear and worm gear, widely used semi-fluid grease, the state of this lipid between the liquid lubricant and plastic grease. Semi-fluid greases are composed of dispersion media and disperse phase (thickener), similar to plastic greases. However, due to the small amount of thickener, the semi-fluid grease flows in the same way as the lubricating oil due to its own weight without any applied load. The characteristics of semi-fluid grease determine it has a series of advantages over liquid-based lubricants. For example, the use of semi-fluid grease in the gear unit saves on complex and expensive sealing costs, greatly reduces grease consumption and simplifies the design of
