用于涡轮机叶轮平衡料移除的方法
摘要：
用于涡轮增压器的涡轮机叶轮(10)包括在轴向方向上在鼻状部分(14)与后壁(22)之间延伸的一个轮毂(12)。该轮毂(12)限定了在轴向方向上延伸的旋转轴线(28)并且该后壁(22)包括一个外围边缘(20)。多个涡轮叶片(26)被联接到轮毂(12)上并且在围绕该旋转轴线(28)的圆周方向上是总体上以相等的间隔布置的。在该后壁(22)的外围边缘(20)上形成了至少一个扇形部分(44，48)以用于平衡该涡轮机叶轮(10)。至少一个扇形部分(44，48)是沿外围边缘(20)布置的使得该外围边缘(20)在围绕该旋转轴线(28)的圆周方向上不是对称的。
摘要（英）：

A turbine wheel (10) for a turbocharger includes a hub (12) extending in an axial direction between a nose (14) and a back-wall (22). The hub (12) defines an axis of rotation (28) extending in the axial direction and the back-wall (22) includes a peripheral edge (20). A plurality of turbine blades (26) is coupled to the hub (12) and is disposed in a circumferential direction generally at equal intervals around the axis of rotation (28). At least one scallop (44, 48) is formed in the peripheral edge (20) of the back-wall (22) for balancing the turbine wheel (10). The at least one scallop (44, 48) is positioned along the peripheral edge (20) such that the peripheral edge (20) is not symmetrical in the circumferential direction about the axis of rotation (28).
