Abstract
A vane ring assembly includes a lower vane ring (), an upper vane ring (), one or more guide vanes () positioned at least partially between the vane rings, and a spacer () positioned between the lower and upper vane rings () for maintaining a distance between the lower and upper vane rings (). The spacer has a first end () with a first diameter, a second end () with a second diameter, and a middle section () with a third diameter. The third diameter is larger than the first and second diameters. The first and second ends () of the spacer () are inserted at least partially into a first counter bore () and a second counter bore () formed in the lower and upper vane rings (). A nut () and a fastener () running through a central through hole () of the spacer () 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 () of the spacer () an outside wall () of the metal fastener () to offset any thermal expansion or deformation.
