Method for joining bearing housing segments of a turbocharger incorporating an electric motor

A bearing housing (12) for a turbocharger (10) includes a split (60) defining a first bearing housing segment (62) and a second bearing housing segment (64). At least one channel (74, 84) for transporting fluid within the bearing housing (12) crosses the split (60) such that the channel (74, 84) ext...

Zusammenfassung:	A bearing housing (12) for a turbocharger (10) includes a split (60) defining a first bearing housing segment (62) and a second bearing housing segment (64). At least one channel (74, 84) for transporting fluid within the bearing housing (12) crosses the split (60) such that the channel (74, 84) extends within the first bearing housing segment (62) and the second bearing housing segment (64). A dowel (82, 92) having a hollow interior is inserted in the channel (74, 84) to align the first and second bearing housing segments (62, 64) and allows fluid to flow through the channel (74, 84). The invention further discloses a turbocharger incorporating an electric motor. 本申请公开了种用于涡轮增压器(10)的轴承壳体(12)，其包括个缝(60)，该缝限定了个第轴承壳体区段(62)和个第二轴承壳体区段(64)。至少个用于在该轴承壳体(12)内传输流体的通道(74，84)穿过该缝(60)使得该通道(74，84)在该第轴承壳体区段(62)与该第二轴承壳体区段(64)内延伸。个具有空心内部的定位销(82，92)被插入该通道(74，84)中以便与该第轴承壳体区段和第二轴承壳体区段(62，64)对准并且允许流体流动通过该通道(74，84)。本申请还公开了种包括电动马达的涡轮增压器。
