Abstract
A bearing heat shield, a turbomachine having a bearing heat shield and method for assembling such is disclosed. The bearing heat shield includes an outer annular ring extending around an outer circumference of the bearing heat shield, the outer annular ring has a flat surface and extends inward from an outer diameter measurement to a middle diameter measurement. The bearing heat shield further includes a concave surface, the concave surface being defined by a curvature and extending inward from the middle diameter measurement to an inner diameter measurement.
Claims20
A bearing heat shield comprising:
- an outer annular ring extending around an outer circumference of the bearing heat shield, the outer annular ring having a flat surface and extending inward from an outer diameter measurement to a middle diameter measurement;
- and
- a concave surface, the concave surface defined by a curvature and extending inward from the middle diameter measurement to an inner diameter measurement.
A turbomachine comprising:
- a turbine housing;
- a turbine wheel disposed in the turbine housing and configured to rotate about an axis;
- a bearing housing adjacent to the turbine housing;
- and
- a bearing heat shield disposed between the turbine housing and the bearing housing, the bearing heat shield including:
- an outer annular ring extending around an outer circumference of the bearing heat shield, the outer annular ring having a flat surface and extending inward from an outer diameter measurement to a middle diameter measurement;
- and
- a concave surface, the concave surface defined by a constant radius measurement and extending inward from the middle diameter measurement to an inner diameter measurement.
A method comprising:
- obtaining a bearing heat shield, the bearing heat shield having:
- an outer annular ring extending around an outer circumference of the bearing heat shield, the outer annular ring having a flat surface and extending inward from an outer diameter measurement to a middle diameter measurement;
- and
- a concave surface, the concave surface defined by a constant radius measurement and extending inward from the middle diameter measurement to an inner diameter measurement;
- installing the bearing heat shield to a bearing housing;
- and
- installing a turbine housing to sandwich the outer annular ring of the bearing heat shield between the bearing housing and the turbine housing.
