Variable preload shaft bearing for turbocharger |
摘要 |
A rotating shaft of a turbocharger is supported by two rolling bearings enclosed in a bearing housing. Two collar members are interposed between the housing and bearings for supporting the bearings in the housing. A U-shaped preloading member is interposed between the two collar members in such a manner that the U-shaped member forms an oil chamber therein. The U-shaped member receives a pressure of a lubricating oil supplied to the oil chamber from an engine, and expands to puch the rolling bearings through the collar members with a greater force when the engine speed is high, and therefore, the oil pressure is high.
