The system includes a thrust collar including a cylindrical portion and a flange configured to radially extend from one end of the cylindrical portion. The thrust collar is configured to rotate with the shaft. A sensor is positioned within a separation of an outer surface of the thrust collar flange, and the sensor is configured to monitor the separation as indicative of the radial motion of the shaft. Additionally, a method is provided for monitoring radial motion of a rotating shaft of a turbocharger.

摘要： Compressor wheel and techniques for manufacturing such a wheel are provided. The wheel may include a hub with a counterbore internally treated to impart residual compressive stresses for enhanced endurance to stress-induced fatigue. The surface treatment allows extending the counterbore relatively closer to a plane of typical maximum stress of the wheel. This design flexibility advantageously allows avoiding or reducing overhang of the compressor wheel, thereby improving rotor dynamics and reducing the axial length of the hub, and the overall foot print of the compressor wheel.

摘要： Various systems and apparatuses are provided for a fluid transfer system for an engine. In one example, a system includes a first turbine having an exit for discharging a main fluid flow and a second turbine having an inlet for receiving at least a portion of the main fluid flow. A main conduit fluidically couples the exit of the first turbine to the inlet of the second turbine. A transition conduit is coupled with the main conduit and includes a volute passageway curving around the main conduit. The volute passageway includes a slot that follows a route around the curving volute passageway and opens into an interior of the main conduit. The slot is defined at least in part by a lip and establishes a path for either a secondary fluid flow to enter the main conduit or a portion of a main fluid flow to exit the main conduit.
