Patent number: 8558422Abstract: A liquid-cooled stator and rotor assembly for use as an electric motor or generator includes a housing having a first end bell, a second end bell, and at least one fluid orifice in the first end bell. A stator is fixed within a stator cavity of the housing. The stator includes a stator core and a plurality of windings for conducting a flow of electricity. A rotor for magnetically interacting with the stator is also included, the rotor being rotatably mounted between the first end bell and the second end bell within a rotor cavity. A first sealing ring and a second sealing ring are provided to form a fluid seal against the respective end bells and against a portion of the stator such that a cooling fluid entering the stator cavity via the orifice does not enter the rotor cavity.Type: GrantFiled: March 31, 2011Date of Patent: October 15, 2013Assignee: Caterpillar Inc.Inventors: Jonathan Baumann, Perry Cruce

Publication number: 20120024656Abstract: A method of lubricating a clutch disposed on a driven-side of a flywheel that is connected to a crankshaft includes rotating the flywheel and providing a flow of lubrication fluid spilling onto a driver-side of the flywheel. At least a portion of the flow of lubrication fluid is received through at least one passageway extending through the flywheel and expelled from the passageway on a driven-side of the flywheel. A clutch disposed on the driven-side of the flywheel is lubricated with the expelled lubrication fluid.Type: ApplicationFiled: October 11, 2011Publication date: February 2, 2012Applicant: CATERPILLAR INC.Inventors: SATISH SAVANT, DAVID FEE, BRADFORD KOUGH, JONATHAN BAUMANN, PERRY CRUCE, MATTHEW DAMES

Patent number: 8074534Abstract: A flywheel includes a hub portion concentrically defined around a center of the flywheel. A body portion located peripherally around the hub portion has a driver-side face and a driven-side face. A plurality of passageways in the body portion extend through the flywheel and fluidly connect the driver-side face with the driven-side face. Each of the plurality of passageways is adapted to receive a flow of lubricant spilling onto the driver-side of the body portion when the flywheel is rotating, and to expel lubricant out of the driven-side face of the body portion.Type: GrantFiled: July 30, 2007Date of Patent: December 13, 2011Assignee: Caterpillar Inc.Inventors: Satish Savant, David Fee, Bradford Kough, Jonathan Baumann, Perry Cruce, Matthew Dames
