Abstract: 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.

Abstract translation: 通常，涡轮增压器轴承座被铸造，然后将油通道钻入或钻入铸件中。 因此，钻孔限于从钻孔接入点延伸的直线。 通过在模具中预先分配金属管道的集合来提供更大的设计灵活性，金属管道将限定一个或多个油，空气和水库，然后在管道周围铸造轴承壳体。 这在成型和定位油孔等功能方面提供了几乎无限的自由度。
