摘要： The bulldozer has a right first oil channel, a right second oil channel, and a right third oil channel. The right first oil channel guides a portion of the lubricating oil discharged by a hydraulic pump to a right steering brake. The right second first oil channel guides a portion of the lubricating oil discharged by the hydraulic pump to a right planetary gear mechanism. The right third oil channel guides at least a portion of the lubricating oil that has passed through the right planetary gear mechanism to a right steering brake. At least a portion of the planetary gear mechanism is disposed further inside than the right steering brake in a radial direction perpendicular to the center axis of an input shaft.

The first drive gear and the second drive gear are arranged along the axis. The first drive gear includes a first extension and the second drive gear includes a second extension arranged radially within and axially overlapping the first extension. The drivetrain system includes a system of bearings arranged between the first drive gear and the second drive gear, either drive gear and a stationary component, or a combination thereof. In some embodiments, the drivetrain system includes a clutch assembly arranged between the first drive gear and the second drive gear that interfaces to the first drive gear and to the second drive gear. The clutch assembly allows the drive gears to be locked or otherwise engaged to improve torque transfer.

摘要： A lubricating oil circuit of a turbomachine includes a distribution valve that distributes an oil flow rate among a first heat exchanger and a bypass duct, connected to an oil duct, which is connected to an heat exchanger positioned against a turbomachine fuel passage duct, and includes a gearbox of a rotation speed reducer that lowers a rotational speed of a first rotary fan shaft of the turbomachine relative to a rotational speed of a second low-pressure compressor rotary shaft of the turbomachine or of a second low-pressure turbine rotary shaft of the turbomachine, and a regulation device. The regulation device includes a local regulation loop that generates an oil flow rate distribution control signal and regulates an oil temperature of the oil duct on a temperature setpoint, and a global regulation loop that generates the temperature setpoint as a function of the temperature and of the temperature setpoint.

摘要： A lubrication distribution system is provided for mechanical systems, including gearboxes, to evenly and precisely apply lubricant to system structures during operation. The system includes a rotating lubrication distribution component that functions both to pump and to precisely direct lubricant. Machined locator elements enable accurate positioning of the rotating lubrication distribution component within the system. A plurality of lateral ports and surface features in the rotating lubrication distribution component receive and distribute lubricant transferred during rotation from one or more lubricant collection components with profiled lubricant transfer elements that enables collection of lubricant from eddies produced by profiles of the lubricant transfer elements during rotation of the rotating lubrication distribution component. Collected lubricant is directed into the rotating lubrication distribution component ports and distributed evenly and precisely to mechanical system or gearbox structures requiring lubrication. An existing gearbox thrust bearing may be modified to receive and precisely distribute lubricant.

摘要： A propelled milling machine includes a cutting rotor that receives power from an internal combustion engine via a rotor drivetrain. To adjust the speed of the cutting rotor, the rotor drivetrain includes a rotor drivetrain transmission operatively associated with a rotor drivetrain lubrication circuit. To regulate temperature of the lubricant, a heat exchanger circuit is associated with the rotor drivetrain lubrication circuit and includes a rotor drivetrain lubricant heat exchanger and a rotor drivetrain lubricant pump assembly. The quantity of lubricant directed to the heat exchanger is regulated based on one or more sensed operating parameters associated with the lubricant.
