ABSTRACT:
A journal bearing for use with a turbocharger includes a free floating bushing rotatable between a shaft and housing. In one embodiment, a single oil feed passage is provided at an angle in the housing, and a number of radially disposed oil transfer passages are provided in the free floating bushing. The angle of the housing passage relative the bushing passages is such that oil flowing between the passages imparts an angular momentum to the bushing opposite the shaft rotation to slow the rotational velocity of the bushing. Alternately, the housing passage may be radially disposed and the bushing passages may be inclined at an angle relative to the housing passage to similarly impart an angular momentum to the floating bushing in a direction opposite the directing of rotation of the shaft, or both the housing passage and the bushing passages may be inclined relative one another to impart an angular momentum to the bushing in a direction opposite the direction of rotation of the shaft.
