  • Thin Film Lubrication | SpringerLink

    The definition of different lubrication regimes is a historic problem (Jost et al. 2000).In boundary lubrication, molecules are absorbed on solid surfaces of a tribo-pair and form a mono-molecular absorbed layer as described by Hardy as shown in Fig. 1a.If the lubricant film thickness in the contact region is in a range from a few …

  • Modified Reynolds equations for thin film

    2020-11-1 · Therefore, bearing characteristics similar to those in the previous paper calculated from the two-side model are shown comparatively with the one-side model. Thin film lubrication analysis of tapered bearings was performed numerically by discretizing the one-dimensional Reynolds equation of Eq. .

  • 7. Lubrication of Bearings - NTN

    2018-5-25 · 7. Lubrication of Bearings In a bearing, lubrication forms a thin oil film on both the rolling surface and sliding surface to prevent metal-to-metal contact. The benefits of lubricating a rolling bearing can be summarized as follows: (1) Alleviation of friction and wear (2) Removal of friction heat (3) Longer bearing life (4) Rust …
