BASIC STUDY OF THE SLIDING CONTACTS IN ROLLING BEARINGS.
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 thickness/roughness 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.
