Abstract

Rolling
element bearings experience dynamic axial thrust and shaft movements of various
frequencies and amplitudes in a multitude of applications, such as drive
trains, industrial gearboxes and heavy-duty machinery like cranes, paper- and
weaving machines, harvesters, crushers or milling plants. These operating
conditions often cause significant friction losses that entail higher operating
temperatures and lower lubricant operating viscosities. Dynamic axial shaft
movements excessively increase shearing between rollers and raceways which
impairs the mechanical stability of the lubricant. In consequence, this may result
in insufficient lubrication or even premature bearing failure. In order to choose
a suitable lubricant for such a bearing application that experiences axial
shaft movements or to be able to adequately enhance the mechanical stability of
the lubricant in this regard, the occurring shear- or friction forces between rollers
and raceways are of particular interest. Therefore, in an experimental study, a
cylindrical roller bearing has been subjected to dynamic axial shaft movements
of various frequencies and amplitudes, utilizing a specifically designed test
rig. Within the scope of this presentation, this test rig is briefly introduced
and the experimental set-up is presented. The results obtained, which include measurements
of axial friction forces between rollers and raceways, operating temperatures
of inner and outer ring, test bearing friction moments, as well as cage
slippage, are discussed in detail. Concluding, a short assessment is given, to
what extend axial shaft movements might exhibit a critical impact on lubricant
performance.
