1.范围 1.1 该方法对做为润滑物的石墨的摩擦性进行估测。 2.方法概述 2.1 石墨悬浮于矿物油中,形成含石墨15％的混合物,该混合液借助螺旋浆和导管装置在滚珠轴承中旋流,轴转速1750转/分运转时间二小时,可确定出轴承重量的损
1. Scope 1.1 This method estimates the friction of graphite as a lubricant. 2. METHOD OVERVIEW 2.1 Graphite is suspended in mineral oil to form a 15% graphite-containing mixture which is swirled in a ball bearing by means of a propeller and a conduit arrangement with a shaft speed of 1750 rpm for two hours to determine Loss of bearing weight
