Abstract
An apparatus has been developed for the measurement of the pressure distribution in the lubricant between a roller and a flat plate in relative motion.
A hole of diameter 0002 in is drilled in a flat plate which is mounted on a co-ordinate table. A traverse of the pressure zone in two directions is effected by moving the co-ordinate table in discrete steps, so that the lubricant pressure at each location is transmitted through the small hole. Connecting to the small hole is a pressure transducer which feeds a signal, proportional to the pressure, to an ultra-violet recorder. Conversion of the recorder print-out to pressure is accomplished by calibration of the transducer and the recorder against known pressures
