Filed:

Jul 27, 2006

Appl. No.:

11/493982

Inventors:

Thomas A. Brosowske - Peoria IL, US
Aaron J. Weber - Fort Wayne IN, US
Scott A. Snoble - Pekin IL, US
Thomas L. Atwell - Peoria IL, US

Assignee:

Caterpillar Inc. - Peoria IL

International Classification:

F16H 55/18

US Classification:

74440, 74409, 74411

Abstract:

A compliant gear assembly includes a gear ring positioned about a hub and configured to translate responsive to a torque on the gear assembly, and biased toward co-axial alignment with the hub via at least one actuator. A method of managing loads on an idler gear in the gear train is still further provided including translating the gear ring responsive to the torque on the idler gear. A work machine includes an engine having a housing and a geartrain mounted thereon, the geartrain including a crank gear, a cam gear and a compliant idler gear assembly.

US Classification:

74440, 74409, 74411, 74443, 74399, 74397

Abstract:

A compliant gear assembly for a gear train of an internal combustion engine includes a hub subassembly having a first hub component and a second hub component. The first hub component defines a first axis, and the compliant gear assembly includes a gear ring rotatable relative to the hub subassembly and defining a gear ring axis of rotation. The second hub component is movable relative to the first hub component in a direction normal to the first axis between a first stop position at which the gear ring axis of rotation is co-linear with the first axis and a second stop position at which the gear ring axis of rotation is parallel to but not co-linear with the first axis. A compliance mechanism is coupled between the first hub component and the second hub component and biases the second hub component toward the first stop position. Translating the second hub component relative to the first hub component in a direction normal to the first axis attenuates torque spikes induced for example via fuel injector actuation and/or cylinder firing in an engine gear train employing the compliant gear assembly.

Appl. No.:

10/310299

Inventors:

Christopher Elliott - Metamora IL, US
Michael Harmon - Dunlap IL, US
Aaron Weber - Peoria IL, US

International Classification:

F02B077/00

US Classification:

123/19800C

Abstract:

An apparatus and method for pumping oil in a machine. The apparatus and method includes a first gear drivably connected to the machine, a second gear connected to the machine such that a set of teeth located on the first gear engage a set of teeth located on the second gear, an oil inlet port located near the teeth of the first gear slightly before a point of engagement of the teeth of the first and second gears, and an oil outlet port located at the point of engagement of the teeth of the first and second gears.
