Embodiment Construction

[0011] figure 1 Shown in is a section of a rotating machine, in this case a generator 10 . The generator 10 includes at least one rotor 12 rotatable about a central axis 14 . The electric machine 10 includes a generator shaft 16 disposed at a central axis 14 and connected to, for example, an engine crankshaft 18 via one or more splined interfaces 20 . now refer to figure 2 , in some embodiments, the spline interface 20 is defined by a plurality of generator shaft teeth 22 meshing with a complementary plurality of crankshaft teeth 24 .

[0012] In some embodiments, such as figure 2 As shown, a plurality of generator shaft teeth 22 extend radially inwardly from an inner surface of a substantially annular generator shaft plate 26 which in some embodiments is welded or otherwise secured to the On the generator shaft 16. Also, in some embodiments, a plurality of crankshaft teeth 24 are disposed at and extend radially outwardly from a crankshaft plate 28 . Crank plate 28 may...

Abstract

The invention relates to a self cleaning grease lubricated spline, especially a lubrication system for a spline interface (20) including at least one debris chamber (46) located radially outboard of the spline interface (20) of a first rotating component (16) and a second rotating component (18). Wear debris (44) is urged from the spline interface (20) toward the at least one debris chamber (46) by rotation of the first and second rotating components (16, 18) about a central axis (14). At least one lubricant reservoir (36) contains a volume of lubricant (40), wherein at least a portion of the volume of lubricant (40) flows toward the spline interface (20) in response to the wear debris (44) being urged from the spline interface (20) toward the at least one debris chamber (46).

Description

technical field [0001] The presently disclosed subject matter relates to rotating machines. More specifically, the subject of the invention relates to splined connections in rotary machines. Background technique [0002] Connections between rotating components of machines, or between machines, are often achieved via spline connections. A splined connection includes male teeth on a first member that engage complementary teeth on a second member. The splined connection allows efficient transfer of rotational energy of the first member to the second member. During the life of the spline, particles are generated, for example due to wear of the spline teeth, and must be removed from the spline to ensure continued operation of the spline connection. Typically, a pressurized lubrication system is employed that sprays a lubricant, such as lubricating oil, through an external pump into the splined connection to flush out any accumulated particulates. The oil is then generally dis...
