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.Authors with CRIS profile
