TURBOCHARGER BEARING HOUSING WITH CAST- IN PIPES |
| 摘要 |
Conventionally, turbocharger bearing housings are cast, and then oil passageways are drilled or bored into the casting. As a result, bores are limited to straight lines extending from drill access points. Greater design flexibility is provided by pre-staging in a mold a collection of metal pipes which will define one or more of oil, air and water galleries, and then casting a bearing housing around the pipes. This provides almost unlimited freedom in shaping and locating the oil bores and other features. |

1. A method of manufacturing a turbocharger bearing housing, the method comprising:
preparing a pipe bundle (71, 74, 77, 78) including at least one pipe for defining at least one oil gallery, and casting the bearing housing (60) around the pipe bundle to form a bearing housing with said pipe defining an oil gallery. |
