    Abstract: An electric machine may include a rotor shaft that has a hollow region configured to receive a coolant. The hollow region is defined by an inner surface which has a slope that increases from a first inner diameter at a first end to a second inner diameter at a second end. Centrifugal force generated when rotating the rotor shaft causes the coolant to flow across the inner surface of the rotor shaft from the first end to the second end at a velocity depending at least in part on the slope of the inner surface of the rotor shaft. A method of cooling an electric machine includes injecting a coolant into a first end of the hollow region of the rotor shaft, rotating the rotor shaft at an operational rate of rotation, with the rotation generating centrifugal force that causes the coolant to flow from the first end to the second end, transferring heat from the rotor shaft to the coolant.

    Abstract: Oil sump seal pressurization apparatus for turbine engines are disclosed. An example oil sump seal pressurization apparatus may include a non-rotating oil sump housing a bearing; an oil seal isolating an interior of the oil sump; a passage arranged to supply pressurization air to an outward side of the oil seal; a drain arranged to allow draining of oil and venting of at least some of the pressurization air, the drain being positioned axially between the passage and the oil seal; a wide discourager tooth disposed on the shaft and extending radially outward towards a non-rotating land, which may be disposed axially between the passage and the drain, the wide discourager tooth being spaced apart from the land in a radial direction by a gap, the wide discourager tooth including an upper surface; and/or an adjacent tooth disposed on the shaft and extending radially outward from the shaft.

    Abstract: Oil sump seal pressurization apparatus for a turbine engine are disclosed. An example oil sump seal pressurization apparatus may include an oil sump comprising at least one bearing mounted therein; an oil seal operatively disposed between a non-rotating structural member of the sump and the shaft; a generally radially inwardly oriented passage arranged to supply pressurization air to the outward side of the oil seal; a generally radially outwardly oriented pathway arranged to receive at least some of the pressurization air from the passage, the pathway being at least partially defined by a generally radially outwardly extending arm disposed on the shaft, the arm rotating with the shaft; and/or a windage shield at least partially separating the passage and the pathway, the windage shield being operatively mounted to the non-rotating structural member of the sump.
