Abstract:
A bearing supporting a non-homogeneously or homogeneously loaded rotating component of a motor vehicle engine includes a plurality of bearing portions joined together and forming a substantially cylindrical outer surface and a substantially cylindrical center bore, the substantially cylindrical central bore surrounding and supporting the non-homogeneously or homogeneously loaded rotating component. The bearing having a plurality of bearing layers made of different materials unevenly distributed about a circumference and along a longitudinal axis of the bearing, the bearing layers reactively ovalizing in response to loads imparted by the non-homogeneously or homogeneously rotating components, and changing a minimum lubricating fluid thickness on a portion of the substantially cylindrical central bore that ovalizes in response to transient local loads imparted by the non-homogeneously or homogeneously loaded rotating component.
