摘要： By providing an auxiliary check valve in parallel with a check valve installed in an electric oil pump, it is possible to measure an oil temperature even when the check valve is stuck. A flow resistance of an oil passage of the auxiliary check valve is set so as to be larger than that of the check valve, and a minimum valve open pressure difference of the auxiliary check valve is set so as to be smaller than that of the check valve. Thus, it is possible to further accurately measure an oil temperature and determine a fault. By using a rotation speed of the electric oil pump and an oil temperature in determining whether there is a fault in the electric oil pump or in the oil passage, it is possible to reduce the influence of variations, or the like, in measurement of a temperature sensor.

摘要： A transmission for a wind turbine has a planetary gearset with a fixed sealing surface and at least one cavity. The gearset includes a rotating planetary carrier or a rotating ring gear. The cavity is fixed relative to the carrier or ring gear and has at least one opening. The transmission has an oil reservoir. The carrier or ring gear can rotate to at least three positions. By rotating, the carrier or ring gear can move from the first to the second position and from the second to the third position. In the first position of the carrier or ring gear, oil can flow from the oil reservoir through the opening into the cavity and in the third position the oil can flow through the opening out of the cavity. In the second position of the carrier or ring gear the opening is closed by the sealing surface.

摘要： A lubricating system has been disclosed for gear mechanisms or generators, in particular for gear mechanisms of wind power plants, which lubricating system permits a switchover between dry sump lubrication and wet sump lubrication. This takes place by way of a delivery device which increases the pressure in a lubricant tank selectively or in an emergency, for example a power outage, and presses a lubricant back into an oil sump in the gear mechanism, whereupon a lubricant level is increased there and wet sump lubrication is realized. The delivery device can have a compressor. Said compressor can charge a pressure accumulator via a non-return valve or can increase the pressure in the lubricant tank directly. The delivery device can consist of hydraulic, pneumatic or else electrical components. If it is pneumatic, it can be separated from the hydraulic lubricating system via an elbow.

摘要： A lubrication system includes a reserve housing configured to retain a lubrication fluid. A supply line in fluid communication with the reserve housing is configured to provide pressurized lubrication fluid to the reserve housing. An overflow tube has an overflow port, the overflow tube being configured to prevent the volume of the lubrication fluid from exceeding a certain amount. A metering jet is configured to allow the lubrication fluid to flow from the reserve housing onto a component, such as a bearing, in the gearbox at a predetermined rate. The metering jet provides flow of the lubrication fluid onto the bearing even when the supply line no longer provides pressurized lubrication fluid to the reserve housing.

摘要： A method of controlling a level of fluid in a main sump of a transmission includes opening an auxiliary reservoir with a first valve when fluid temperature in the main sump is at or below the predetermined temperature. The first valve is opened to increase the level of fluid in the main sump to at least a predetermined height so that transmission rotating components contact the fluid and generate splash lubrication. When the transmission is transmitting torque and the fluid is above the predetermined temperature, the level of fluid in the main sump is maintained below a predetermined height with closed first valve, such that the rotating components do not contact the fluid inside the main sump. A fluid pump alone is sufficient to lubricate the rotating components above the predetermined temperature and sufficient to lubricate the rotating components at or below the predetermined temperature only with splash lubrication.

摘要： A lubrication system includes an additive and a delivery system. During normal operational conditions, the lubricating oil circulating in the transmission system is collected and contained in a secondary oil reservoir to retain a quantity of the lubricating oil for use in an oil-out condition. When an oil-out condition is detected, the additive is injected and mixed with the collected lubricating oil in the secondary oil reservoir or dispersed directly into a power transmission gearbox housing to enhance the characteristics of the lubricating oil and increases the operational time period of the power transmission gearbox during an oil-out condition.
