Filed: 2001-09-18
Abstract: A load responsive hydrodynamic bearing is provided in the form of a thrust bearing or journal bearing for supporting, guiding and lubricating a relatively rotatable member to minimize wear thereof responsive to relative rotation under severe load. In the space between spaced relatively rotatable members and in the presence of a liquid or grease lubricant, one or more continuous ring shaped integral generally circular bearing bodies (6) each define at least one dynamic surface (22) and a plurality of support regions (B0). A plurality of flexing regions (37) are defined by the generally circular body of the bearing and are integral with and located between adjacent support regions (B0). Each of the flexing regions (37) has a first beam-like element (38) being connected by an integral flexible hinge (44) with one of the support regions and a second beam-like element (39) having an integral flexible hinge connection with and adjacent support region (B0). At least one local weakening geometry of the flexing region (44) is located intermediate the first and second beam-like elements. In response to application of load from one of the relatively rotatable elements to the bearing, the beam-like elements (38, 39) and the local weakening geometry (44) become flexed, causing the dynamic surface to deform and establish a hydrodynamic geometry for wedging lubricant into the dynamic interface.

Abstract: An oil circulation system that monitors filter life and can notify the operator of the oil filter life status. the oil filter life is calculated based upon oil pressure sensors on the inlet and outlet of the oil filter. Pressure drop, oil temperature, and engine speed from the tachometer are factored into an algorithm to calculate the percentage of oil filter life remaining. If the percentage is below the predetermined level, the system will warn the operator to change the filter.  If the percentage is above the predetermined level, the system will record the extent of oil filter life remaining and repeat the process.
