  • Bearing insulating system for aircraft turbocharger
    Patent number: 5403150
    Abstract: A turbocharger having a heat insulating system whereby an aluminum bearing housing, its internal components including bearing assemblies and lubricating oil are insulated from the heat of the turbine. The insulating system includes three basic component parts. The first component part is a partially convoluted backplate interconnecting the bearing housing and the turbine housing. The second component part is an insulator situated next to the backplate and the third component part is a heat shield provided between the turbine wheel and the insulator. Between the backplate and the bearing housing is defined a cavity near the turbine shaft. Oil slingers are provided on the shaft within the cavity to create an oil-air mist when the shaft is rotated, thereby enhancing cooling.
