    Abstract: A disc, rotated continuously by a variable-speed driving means, has friction members clamped against its opposite faces by means of a calibrated, adjustable mechanism which controls the ''''normal'''' force holding the members against the disc. The friction force between the members and the disc may be determined by measuring the tangential force produced on the members as the disc rotates. One edge of the disc dips into a bath of the lubricant being tested, to provide lubricant at the juxtaposed disc and member surfaces. A heating means may be provided for the bath, to enable testing at elevated temperatures.

    Abstract translation: 通过可变速度驱动装置连续旋转的盘片具有通过校准的可调节机构夹紧抵靠其相对面的摩擦构件,该机构控制将构件保持抵靠盘的“正常”力。 可以通过测量当盘旋转时在构件上产生的切向力来确定构件和盘之间的摩擦力。 盘的一个边缘浸入待测润滑剂的浴中,以在并置的盘和构件表面提供润滑剂。 可以为浴提供加热装置,以使得能够在升高的温度下进行测试。
