Abstract:
A 2-ball test machine, especially designed for sliding tests and capable of being used with irradiated balls for purposes of wear determination, was used to determine the load-speed relationship at the initiation of smearing failure in a sliding 2-ball configuration for three highly refined mineral oils and three ester-type lubricants. A configuration of three crowned cylindrical rollers was operated between two flat thrust washers in the presence of a non-metallic cage. The elastohydrodynamic film condition between rollers and flat washers was determined using a previously developed contact conductivity method. Preliminary surface microgeometry tracings were made on the test elements and the required modification of statistical theories relating conductivity results to the film thicknessroughness ratio was accomplished. Kinematical studies were made of the axial roller motion and skew of cylindrical rollers running in a conventional cylindrical roller bearing with flanged outer ring, in aligned or misaligned conditions.
