Turbine for internal combustion engine

The invention relates to a turbine (1) for an internal combustion engine. The turbine comprises a shaft (2) and a rolling bearing (3) for supporting the shaft (2). The rolling bearing (3) has at least one inner ring (4a, 4b), at least one outer ring (5) and rolling bodies (6a, 6b) arranged spatially between the at least one inner ring (4a, 4b) and the at least one outer ring (5). At least the at least one inner ring (4a, 4b) is constructed from a steel alloy. The steel alloy has at least 5.8 to up to 6.2% by weight of nickel, at least 4.8 to up to 5.2% by weight of chromium, at least 2.0 to up to 2.4% by weight of aluminum, at least 0.6 to up to 0.8% by weight of molybdenum, and at least 0.45 to up to 0.55% by weight of vanadium. 本发明涉及一种用于内燃机的涡轮机(1)，所述涡轮机包括轴(2)和用于支承所述轴(2)的滚动轴承(3)，其中，所述滚动轴承(3)具有至少一个内圈(4a、4b)、至少一个外圈(5)以及在空间上布置在所述至少一个内圈(4a、4b)和所述至少一个外圈(5)之间的滚动体(6a、6b)，其中，至少所述至少一个内圈(4a、4b)由钢合金构造，其中，所述钢合金具有至少5.8至最高6.2重量％的镍、至少4.8至最高5.2重量％的铬、至少2.0至最高2.4重量％的铝、至少0.6至最高0.8重量％的钼和至少0.45至最高0.55重量％的钒。
