Abstract
An exemplary bore for a shaft of a turbomachine includes a longitudinal axis extending generally from an inner end to an outer end of the bore, an outer seat disposed proximate to the outer end of the bore at an outer seat radius for an outer seal ring wherein the outer seat comprises an inner end, an outer end, a step at the inner end extending radially inward to a step radius, and a chamfer at the outer end extending radially inward over an outward axial distance to a chamfer plateau radius and an inner seat disposed inward the outer seat at an inner seat radius for an inner seal ring wherein the outer seat radius exceeds the inner seat radius. Various other exemplary devices, systems, methods, etc., are also disclosed.
Claims13
A bore for a shaft of a turbomachine, the bore comprising:
- a longitudinal axis extending generally from an inner end to an outer end of the bore;
- an outer seat disposed proximate to the outer end of the bore at an outer seat radius for an outer seal ring wherein the outer seat comprises an inner end, an outer end, a step at the inner end extending radially inward to a step radius, and a chamfer at the outer end extending radially inward over an outward axial distance to a chamfer plateau radius.
A bore for a shaft of a turbomachine, the bore comprising:
- a longitudinal axis extending generally from an inner end to an outer end of the bore;
- an outer seat disposed proximate to the outer end of the bore at an outer seat radius for an outer seal ring wherein the outer seat comprises an inner end, an outer end, a step at the inner end extending radially inward to a step radius, and a chamfer at the outer end extending radially inward over an outward axial distance to a chamfer plateau radius;
- and
- an inner seat disposed inward the outer seat at an inner seat radius for an inner seal ring wherein the outer seat radius exceeds the inner seat radius.
A turbocharger comprising:
- a compressor comprising a compressor housing and a compressor wheel mounted in the compressor housing;
- a turbine, comprising a turbine housing and a turbine wheel mounted in the turbine housing;
- a shaft connecting the compressor wheel to the turbine wheel;
- a center housing disposed between and mounted to the compressor and turbine housings, the center housing defining a bore that receives the shaft therethrough;
- wherein the bore comprises:
- a longitudinal axis extending generally from an inner end to an outer end of the bore;
- an outer seat disposed proximate to the outer end of the bore at an outer seat radius wherein the outer seat comprises an inner end, an outer end, a step at the inner end extending radially inward to a step radius, and a chamfer at the outer end extending radially inward over an outward axial distance to a chamfer plateau radius.
