OIL SLINGER WITH CONVECTIVE COOLING OF RADIAL SURFACE
First Claim
Patent Images
1. An oil slinger system comprising:
- a seal runner comprising an annular radial member having a radius (R) and an outer axially extending member having an axial length (L) such that a ratio (L/R) is between 0.8 and 1.4, the annular radial member disposed at a first angle with respect to the outer axially extending member;
a heat shield in mechanical communication with the seal runner; and
a volume bounded by an outer face of the annular radial member and an inner face of the heat shield.

Abstract
Oil slinger systems include a seal runner comprising an annular radial member having a radius (R) and an outer axially extending member having an axial length (L) such that a ratio (L/R) is between 0.8 and 1.4, the annular radial member disposed at a first angle with respect to the outer axially extending member, a heat shield in mechanical communication with the seal runner, and a volume bounded by an outer face of the annular radial member and an inner face of the heat shield. Methods of radial convective cooling include pumping a cooling liquid through the oil slinger system and convectively cooling the oil slinger.

15. A method of assembling an oil slinger system comprising:
-
disposing a heat shield in mechanical communication with a seal runner, wherein the seal runner comprises an annular radial member having a radius (R) and an outer axially extending member having an axial length (L) such that a ratio (L/R) is between 0.8 and 1.4, the annular radial member disposed at a first angle with respect to the outer axially extending member; pressing the seal runner axially onto a shaft; and forming a volume bounded by an outer face of the annular radial member and an inner face of the heat shield. - View Dependent Claims (16, 17, 18)
