International Classification:

F16H 39/10
F16H 61/48

US Classification:

60489, 60487

Abstract:

A hydraulic differential with a variable displacement hydraulic unit of the axial piston type, a fixed displacement hydraulic unit of the axial piston type, a stationary housing for mounting the hydraulic units, an input shaft for coupling to a variable speed power source and an output shaft for coupling to a constant speed load, comprises: a wobbler and a port plate for the variable displacement hydraulic unit coupled to the stationary housing; an axial block and piston set for the variable displacement hydraulic unit, a port plate for the fixed displacement hydraulic unit and a wobbler for the fixed displacement hydraulic unit coupled to the input shaft; and an axial block and piston set for the fixed displacement hydraulic unit coupled to the output shaft; wherein the variable displacement hydraulic unit port plate and the fixed displacement hydraulic unit port plate couple together through a circumferential interface to minimise hydraulic thrust forces developed by the hydraulic unit.

David S. Behling - Belvidere IL, US

Assignee:

Hamilton Sundstrand Corporation - Rockford IL

International Classification:

F02C 1/00
F02C 3/10

US Classification:

60 39163, 60802, 74664, 475 6

Abstract:

A turbine engine includes low and high pressure spools. A high power take-off shaft is coupled to the high spool. An auxiliary component, such as a generator, is configured to be driven by the high power take-off shaft at a first speed. The low spool, in part, drives the auxiliary component, for example, by interconnecting the high power take-off shaft to a lower power take-off shaft through a speed summing gearbox. The gearbox drives the auxiliary component and increases the rotational speed of the auxiliary component from the first speed to the second speed. The low power take-off shaft also drives another generator, in one example. The turbine engine can be started by the low pressure generator, for example, in response to a command from a controller, which transforms the generator into a starter motor.

Assignee:

Hamilton Sundstrand Corporation - Windsor Locks CT

International Classification:

F16K 25/00
F16K 51/00

US Classification:

1374546, 13762537, 251 635

Abstract:

A generator includes a rotor to be driven to rotate and generate electricity and a housing receiving the rotor. An oil supply includes an oil inlet port and an oil outlet port. A pressure regulating valve regulates the flow of oil from the inlet port to the outlet port. The pressure regulating valve includes a valve sleeve mounted within the housing. The valve sleeve extends into a bore within the housing. A valve spool is mounted within the valve sleeve. The valve sleeve has a flange abutting an outer face of the housing. Bolts tighten the flange against the housing. An inner end of the valve sleeve extends radially inwardly to form a ledge. The ledge is spaced away from an inner face of the housing. A valve sleeve, a sense piston and a valve spool are also disclosed and claimed.

Inventors:

David S. Behling - Belvidere IL, US

Assignee:

Hamilton Sundstrand Corporation - Windsor Locks CT

International Classification:

F16H 47/00

US Classification:

747331

Abstract:

An example mechanical transmission assembly receives an input rotating at a first rotational speed and provides an output rotating at a second rotational speed. The mechanical transmission selectively adjusts the second rotational speed. The input is provided by a prime mover. The output is provided to a hydraulic pump assembly that rotatably drives a motor-generator.

Assignee:

Hamilton Sundstrand Corporation - Windsor Locks CT

International Classification:

F01D 15/02

US Classification:

4151221, 416170 R

Abstract:

An example gear arrangement includes a gearbox shaft and a journal shaft. The journal shaft establishes an opening that receives an end portion of the gearbox shaft. The gearbox shaft is configured to rotate the journal shaft. The journal shaft is configured to selectively rotatably couple with another shaft. The journal shaft is allowed to align to the bearing surface while the gearbox shaft allows for misalignment between the accessory and gearbox drive.

International Classification:

H02K 7/116

US Classification:

310 83

Abstract:

A generator includes a drive gear mounted to a main rotor shaft though a drive gear bearing and an input jaw plate keyed to the drive gear for rotation therewith, the input jaw plate defines input jaws which selectively mesh with the disconnect jaws, the disconnect shaft axially movable in response to a disconnect system which axially separates input jaws and the disconnect jaws to permit relative rotation between a main rotor shaft and the drive gear through the drive gear bearing.
