Abstract
Methods and systems are provided for an engine housing assembly. In one example, an engine housing assembly comprises an engine housing component, the housing component at least partially defining a first bore for receiving a first shaft and at least partially defining a second bore for receiving a second shaft; and a reinforcement member cast into the housing, the reinforcement member having a lower coefficient of thermal expansion than the housing component, wherein the reinforcement member at least partially surrounds the first and second bores. A method of manufacturing the engine housing assembly is also provided.

An engine housing assembly comprising:
- an engine housing component at least partially defining a first bore for receiving a first shaft and at least partially defining a second bore for receiving a second shaft;
- and
- a reinforcement member cast into engine the housing component, the reinforcement member having a different coefficient of thermal expansion from the housing component, wherein the reinforcement member at least partially surrounds the first and second bores.
An engine assembly comprising:
- an engine housing component at least partially defining a first bore for receiving a first shaft and at least partially defining a second bore for receiving a second shaft, wherein a first shaft assembly comprises a first gear wheel, and a second shaft assembly comprises a second gear wheel configured to mesh with the first gear wheel;
- and
- a reinforcement member cast into engine the housing component, the reinforcement member having a different coefficient of thermal expansion from the housing component, wherein the reinforcement member at least partially surrounds the first and second bores.
A method of manufacturing an engine housing assembly, the method comprising:
- fabricating a reinforcement member for an engine housing component;
- fabricating the engine housing component with the reinforcement member cast into the engine housing component, wherein the engine housing component at least partially defines a first bore for receiving a first shaft and at least partially defines a second bore for receiving a second shaft, wherein the reinforcement member at least partially surrounds the first and second bores and wherein the reinforcement member has a different coefficient of thermal expansion from the engine housing component.
