摘要： The self-pumping hydrodynamic radial sliding bearing (4) exhibits a pump block (11) arranged between two radial sliding bearing segments (13) beneath the lowest point of the generator shaft (1). The pump block (11) has, in its concave cylindrical surface facing the generator shaft (1), pump pockets (28) in the form of flat depressions into which the lubricating oil is drawn by hydrodynamic effect through ducts (25, 27) out of the lubricating oil sump (54) and forced by damming at transverse webs (30) at the end of the pump pockets (28) through further ducts (29', 29, and 22) into the lubricating oil circuit.

摘要： An oil pump is disclosed for a motor-driven apparatus and in particular for lubricating the cutting chain of a chain saw. The oil pump has a pump piston that is rotatable about its longitudinal axis and has a control cam for its axial reciprocation, which as it revolves comes into contact engagement with a control bolt. A control slide upon which a biasing force is exerted is associated with the pump piston. The stroke of the pump piston is limited during normal operation by means of the control slide. If an increased amount of lubricating oil is required, the limitation on the piston stroke effected by the control slide is overcome by moving the control slide away from the pump piston counter to its biasing force, so that the pump piston can move through its maximum total stroke as predetermined by the control cam.

摘要： A gas turbine engine oil system is provided in which the centrifugal separator is arranged to act as a pump for supplying bearing chambers directly, and the scavenging of the bearing chambers is achieved primarily by the pressurization air which flows into the chambers to prevent oil leakage. To avoid the use of pressure regulating valves for controlling the oil flow an oil tank is pressurized and communicates with an auxiliary outlet from the separator, the pressure in which is governed by the quantity of oil flowing around the system. The tank and the bearing chambers are fluidly connected to the centrifugal separator in two separate fluid circuits with each circuit having the separator as an element thereof.

摘要： A refrigerant compressor suitable for use in refrigerators, air conditioners, heat pumps or the like apparatus. The refrigerant compressor has a closed casing which encases a driving electric motor section and a compressor section constructed as a unit. The compressor section has a substantially horizontal crank shaft consisting of a main shaft portion fixed to one end of the rotor of the driving motor, an eccentric portion rotatably carrying a rotary piston and an end journal portion. The lubrication system of this compressor has a passage means for introducing a lubricating oil to various parts requiring lubrication, and a lubricator adapted to supply the lubrication oil to the passage means. The passage means includes a peripheral oil groove formed in the portion having crank shaft of the minimum eccentricity and connected at its one end to a peripheral oil groove formed in the main shaft portion and at its other end to a peripheral oil groove in the journal portion of the crank shaft. The lubricator includes a curved oil pipe fixed at its one end and immersed at its other end in the lubricating oil collected in the closed casing, and a coiled spring rotatably received by the oil pipe and connected at its one end to the journal portion of the crank shaft while the other end is immersed in the lubricating oil through the end opening of the oil pipe.

摘要： A lubricant pump especially suitable for automotive transmissions and the like employing mating gears, at least one of which extends into a sump in a lower casing area. A channeldefining adapter receives the teeth of two mating gears as they converge toward the area of gear engagement. The adapter and that part of its channel receiving the teeth of at least one gear extend below the lubricant level in the sump to substantially close the spaces between adjacent gear teeth, thus defining compartments within which lubricant is transported toward the location at which the gears converge. By virtue of the increased pressure at the convergence of the gear teeth, the transported lubricant is pumped through an outlet passage in the adapter adjacent the area of gear engagement for remote lubrication of other components. One or both of the mating gears may extend into the lubricant of the sump.

摘要： 1,102,459. Bearings; lubricating. ROLLSROYCE Ltd. 17 Nov., 1966, No. 51597/66. Heading F2A. [Also in Division F1] A bearing 10 supports a hollow rotatable shaft 4 in a fixed structure 11 and is supplied with lubricant by means of screw-feed devices disposed within the shaft 4. In an embodiment, a gas turbine has coaxial inner and outer shafts 2, 4 having a low-pressure turbine 1 and a high-pressure turbine 3 mounted thereon respectively and driving low and high pressure compressors 5, 6. The outer shaft 4 is mounted in roller bearings 10, each having an outer race 14 attached to a fixed structure 11 and an inner race 13 attached to the outer rotatable shaft 4. The shaft 2 has screw-devices 19, 23 formed or mounted thereon, the screw-devices being separated axially by an annular space 21. Each screw-device is provided with a number of parallel helical grooves, the helical grooves 20 on the screw-device 19 being of opposite hand to the helical grooves 24 on the screw-device 23. In use lubricant, supplied by a pipe 17 to the helical grooves 20, is pumped by the rotary action of the shaft 2 and enters the annular space 21. The lubricant is prevented from escaping by the helical grooves 24 and is conveyed to the bearings 10, via drillings 22 in the outer shaft 4 and an annular duct 16 and channels 15 in the inner race 13. In a modification, the screw-feed devices 19, 23 may be provided on the internal surface of the shaft 4.
