    • A vane ring assembly includes a lower vane ring (20), an upper vane ring (30), one or more guide vanes (80) positioned at least partially between the vane rings, and a spacer (50) positioned between the lower and upper vane rings (20, 30) for maintaining a distance between the lower and upper vane rings (20, 30). The spacer has a first end (52) with a first diameter, a second end (54) with a second diameter, and a middle section (56) with a third diameter. The third diameter is larger than the first and second diameters. The first and second ends (52, 54) of the spacer (50) are inserted at least partially into a first counter bore (22) and a second counter bore (32) formed in the lower and upper vane rings (20, 30). A nut (40) and a fastener (42) running through a central through hole (58) of the spacer (50) are used to connect the vane ring assembly to a turbocharger housing. A clearance (c) of greater than e.g. 5% of the fastener diameter is formed between an inside wall (51) of the spacer (50) an outside wall (43) of the metal fastener (42) to offset any thermal expansion or deformation.
    • 叶片环组件包括下叶片环(20),上叶片环(30),至少部分地位于叶片环之间的一个或多个导向叶片(80)和定位在下部和上部之间的间隔件(50) 叶片环(20,30),用于保持下叶片和上叶片环(20,30)之间的距离。 间隔件具有第一直径的第一端(52),具有第二直径的第二端(54)和具有第三直径的中间部分(56)。 第三直径大于第一直径和第二直径。 间隔件(50)的第一和第二端部(52,54)至少部分地插入形成在下部和上部叶片环(20,30)中的第一沉孔(22)和第二沉孔(32)中, 。 使用贯穿间隔件(50)的中心通孔(58)的螺母(40)和紧固件(42)将叶片环组件连接到涡轮增压器壳体。 间隙(c)大于例如 5%的紧固件直径形成在间隔件(50)的内壁(51)与金属紧固件(42)的外壁(43)之间,以抵消任何热膨胀或变形。
