涡轮增压器
摘要：
该涡轮增压器(1)具备：旋转轴(4)，其沿轴线(O)延伸；涡轮转子(2)，其设于所述旋转轴(4)的一端侧；压缩机转子(3)，其设于所述旋转轴(4)的另一端侧；滚动轴承(5)，其在所述涡轮转子(2)与所述压缩机转子(3)之间将所述旋转轴(4)支承为能够绕所述轴线(O)旋转；壳体(6)，其从外周侧覆盖所述滚动轴承(5)；至少一部分由减振材料构成的筒状的套筒(80A)，该套筒(80A)设于所述壳体(6)内，以在与所述外圈(51)之间隔开保持润滑油的间隙(S)的方式配置于所述滚动轴承(5)的外圈(51)的外周侧。
摘要（英）：

A turbocharger (1) includes a rotating shaft (4) which extends along an axial line (O) thereof, a turbine rotor (2) which is provided on one end side of the rotating shaft (4), a compressor rotor (3) which is provided on the other end side of the rotating shaft (4), a roller bearing (5) which rotatably supports the rotating shaft (4) around the axis line (O) between the turbine rotor (2) and the compressor rotor (3), a housing (6) which covers the roller bearing (5) from an outer peripheral side of the roller bearing, and a tubular sleeve (80A) which is provided inside the housing (6), which is disposed on an outer peripheral side of an outer ring (51) of the roller bearing (5) with a gap (S) for holding a lubricant between the sleeve (80A) and the outer ring (51), and at least part of which is formed of a damping material.
