摘要:
One embodiment may include a gear assembly comprising at least one pair of meshing gears situated inside a gear case having a sump portion and a wall portion. A gear oil mixture may be disposed at least in the sump portion. At least one gear is immersed partially or fully in the oil mixture. The oil mixture comprises a hydrocarbon oil base and a coolant having an endothermic liquid/vapor transition at a temperature between the lower and upper operating temperatures of the gear assembly.

In a broad aspect of the invention there are provided liquid infused surfaces that feature drag reducing characteristics.In a further broad aspect, the present invention provides methods for designing and fabricating liquid infused surfaces that feature drag reducing characteristics.In a yet further broad aspect the present invention provides methods for increasing the operating efficiency of systems in which a flowing bulk fluid is in contact with a patterned surface, the increased operating efficiency specifically being realized from a reduction of the drag forces due to the bulk fluid flowing over the patterned surface.
摘要:
An operable transmission comprising toothed wheels. In order to operate the transmission with a lubricant and coolant which is environmentally friendly while providing improved heat dissipation and temperature-independent viscosity, the transmission contains a mixture of water and a glycol or similar, in which graphite particles are suspended. The mixture contains 40 to 60 percent per weight of the glycol and 2 to 25 percent by weight of graphite in the form of flaky graphite particles having a grain size of less than 12 micrometers, the remainder being composed of water and other admixtures and/or additives. Also disclosed are the lubricant and coolant as well as a method for starting a transmission operated with the lubricant and coolant.

A method for recycling cutting fluid includes preparing and processing a cutting fluid of silicon including a silicon mixture and a cutting fluid at an anoxic circumstance of 150° C. to 350° C. in a container, to obtain a vaporized cutting fluid and a silicon slurry; and condensing the vaporized cutting fluid to obtain a recycling cutting fluid.
摘要:
A process for lubricating a container, such as a beverage container, or a conveyor for containers, by applying to the container or conveyor, a thin continuous, substantially non-dripping layer of a liquid lubricant. The process provides many advantages compared to the use of a conventional dilute aqueous lubricant.
