油脂对轴承来讲有两个作用,一是封存,二是润滑。目前,大多数把封存用油和润滑用油分开来,这样,在轴承使用时,必须先把封存油清洗后再加入润滑油脂,不仅使用不便,而且造成油脂浪费。最理想的是只用一种油脂,既能起到防锈封存作用,又能起到润滑作用。一九七五年初,上海微型轴承厂要求我们为他们试制微型轴承封存、润滑两用脂,而且要求价格便宜,原料立足国内。我们在接受任务后,在我厂原精密机床主轴脂的基 Grease on the bearing in terms of two roles, first, sealed, and second, lubrication. At present, most of the sealing oil and lubricating oil separate, so that when the bearing is used, you must first seal oil and then add grease, not only the use of inconvenience, but also resulting in waste of grease. The ideal is only a grease, can play a rust-proof storage, but also play a role in lubrication. In early 1975, Shanghai Miniature Bearing Factory asked us to try miniature bearings for them to seal and lubricate dual-purpose grease, and they demanded that they should be cheaper and their raw materials should be based on the domestic market. We accept the task, the original precision machine tool spindle grease base
