PROBLEM TO BE SOLVED: To provide a journal bearing that is for use with turbochargers. SOLUTION: The journal bearing includes a free floating bushing 106 rotatable between a shaft 102 and a housing. In one embodiment, a single oil feed passage 108 is provided at an angle in the housing, and a number of radially disposed oil transfer passages 110 are provided in the free floating bushing 106. The angle of the housing passage 108 relative to the bushing passages 110 is such that oil flowing between the passages imparts an angular momentum to the bushing 106 opposite the shaft rotation to slow the rotational velocity of the bushing 106. Alternatively, the housing passage 108 may be radially disposed and the bushing passages 110 may be inclined at an angle relative to the housing passage 108 to similarly impart an angular momentum to the bushing 106 opposite the shaft rotation. |
