'Railway application - Wheel bearings with rotating outer ring - Rig performance testing
Abstract
'This document specifies a possible test setup and test methodology on how bearing arrangements can be tested in which the bearing outer ring instead of the inner ring is the rotating component. The bearing arrangement can be based on cartridge bearings but also on a symmetric or asymmetric combination of single row roller bearings which do not constitute a self-contained unit. This document focusses on grease lubricated bearing arrangements. A test setup for oil lubricated bearing arrangements is different. The document also suggests test acceptance criteria based on the thermal behaviour of the bearings which takes the special loading and application conditions into consideration. This document offers the possibility to be referred to if bearing arrangements with rotating outer ring undergo performance testing in line with EN 12082-1 for conventional bearings. The necessary type and extent of testing are specified by the deployment procedure specified in EN 12082-2, with respect to design requirements on the axlebox and its components. A compliance with EN 12080 and EN 12081 of bearing and grease is not a pre-requisite for the application of this document.
