TURBOCHARGER BEARING HOUSING

摘要

There is provided a turbocharger bearing housing having no necessity to use a core and capable of achieving cost reduction. A bearing housing 100 of a turbocharger 10 contains a shaft 20 connecting a turbine 40 and a compressor 30 and turnably supports the shaft 20. The bearing housing 100 of the turbocharger 10 is divided into a turbine-side housing 120 disposed at a turbine 40 side and a compressor-side housing 110 disposed at a compressor 30 side. The turbine-side housing 120 and the compressor-side housing 110 is subjected to machining to thereby form a cooling water passage 130 for supplying cooling water and a lubricating oil passage 140 for supplying lubricating oil.
