BEARING THERMAL RELIEF FAN DRIVE GEAR SYSTEM ASSEMBLY METHOD

BEARING THERMAL RELIEF FAN DRIVE GEAR SYSTEM ASSEMBLY METHOD

A method of assembling mating components (40, 62) includes the steps of heating an inner surface of a first cavity (68) of a first part (62) to generate a first expansion, heating an outer surface of a component (66) surrounding an outer periphery of the first part (62) to generate a second expansio...

Zusammenfassung:A method of assembling mating components (40, 62) includes the steps of heating an inner surface of a first cavity (68) of a first part (62) to generate a first expansion, heating an outer surface of a component (66) surrounding an outer periphery of the first part (62) to generate a second expansion of the component (66) that corresponds to the first expansion of the first part (62), inserting a second part (40) into the first cavity (68) while the first part (62) is in an expanded condition, and cooling the first part (62) to contract around the second part (40).
