Estimating the lifetime of gear lubricants

Abstract

The main goal of this paper is to present methods on how to take oil degradation into account in reliability modeling. Therefore mineral oil based gear lubricant was artificially aged in an oven and reliability data was gathered from exemplary selected tests. For testing the aged oil, three tests were selected: two simple test benches (Brugger test apparatus and a four-ball roller test) and a gear test bench.
