An exhaust gas turbocharger comprising a bearing sleeve (26) for radially bearingly mounting a shaft (14), which sleeve is arranged in a bore (36) of a bearing housing (6) and is secured against rotation. The sleeve (26) has an inner bearing surface (34) and an outer jacket surface (32) at each of its two axial end regions, whereby lubricant present in the gap between the sleeve (26) and the bore (36) achieves a damping effect. With a thin shaft and at high rotational speeds, the exhaust gas turbocharger should have a high degree of functional reliability. It is proposed that the sleeve (26) be subdivided into two axially spaced bearing bushings (20, 22) which are connected to each other by small and substantially rigidly formed bridges (24). The securing devices comprise a rod (46) which lies in contact with one of the bridges (24) and serves only to prevent rotation of the sleeve (26) which otherwise can carry out free floating movements. |
