Abstract: A repaired turbine housing for use in an air cycle machine including a journal bearing bore having an inlet, an outlet, and an inner diameter of about 2.580±0.001 inches (6.553±0.003 centimeters). The repaired turbine housing including a cylindrical insert secured within the journal bearing bore. The cylindrical insert having a first end, a second end, an inner surface, a step located at the first end, and an outer surface with an outer diameter that provides a diametric interference with the inner diameter of the journal bearing bore. The diametric interference being between about 0.000-0.003 inches (0.000-0.008 centimeters). The cylindrical insert being inserted into the inlet of the journal bearing bore up to the step. The step has an outer diameter greater than the outer diameter of the cylindrical insert. The inner surface of the cylindrical insert includes at least one selected inner diameter.

Abstract: A turbine housing includes a turbine inlet plenum and a turbine housing body. The turbine housing body includes a turbine outlet mounting face, a seal plate mounting face, and a center bore formed between the turbine outlet mounting face and the seal plate mounting face. A first support is formed about the turbine inlet plenum and in contact with the turbine housing body. A relief pocket is formed in the first support proximate the seal plate mounting face. The relief pocket is formed at a first distance from a turbine housing center axis of the center bore and at a first depth relative to the seal plate mounting face. A ratio of the first distance to the first depth is between 2.66 and 2.90.

Abstract: A method for repairing a turbine housing of an air cycle machine that includes removing damaged material from a journal bearing bore of the turbine housing and forming the journal bearing bore. Next, the inner diameter of the journal bearing bore is determined and a cylindrical insert is formed. The cylindrical insert includes a first end, a second end, an inner surface, a step located at the first end, and an outer surface with an outer diameter that provides a diametric interference with the inner diameter of the journal bearing bore. The second end of the cylindrical insert is inserted into an inlet of the journal bearing bore up to the step. The cylindrical insert is secured to the turbine housing and both are stress relieved by heating. Following the stress relief, the inner surface of the cylindrical insert is formed and seal grooves are formed on the inner surface.
