Definitions

  • a film of oil 184/7 C R, 55 A, 6.26 collects on the upstream face of the ball and flows v around its surface to the downstream face where it is [56] References Cited v 4 picked up by the air flow and is discharged in the form UNITED STATES PATENTS I of droplets through the discharge orifice.
  • such a device should reclassify substantially all of the oil fog particles into wet usable droplets for reasons of economy and also to minimize contamination of the ambient air to which the air stream is lost, vented or exhausted along with any remaining particles suspended therein.
  • the present invention relates to the general type of device just referred to and is a highly efficient reclassifier characterized by a generally spherical chamber having a ball supported therein, providing a space thereon about and through which the aerosol fiows from a supply orifice to a diametrically disposed discharge orifice. Impingement of the stream on the upstream face of the ball wets same with precipitated particles and this film flows around the surface of the ball to its downstream face where droplets of discrete size are picked up by the air flow and discharged through the discharge orifice.
  • the quantity of reclassified particles per unit time may be varied between wide limits to thus satisfy the lubrication requirements of various machines, bearings, moving parts, etc.
  • FIG. 1 is a longitudinal central section of the subject of the invention, a portion being broken away, and illustrated about seven times actual size;
  • FIG. 2 is a section taken on line 2-2, FIG. 1, the ball shown in FIG. I being omitted;
  • FIG. 3 is a section taken on line 33, FIG. 2;
  • FIG. 4 is an exploded view of a modification of portions of FIG. 1.
  • the subject of the invention comprises a body member or pipe fitting having at one end a bore 14 to which aerosol is supplied and threads 12 at its other end adapted to be connected to a machine part adjacent a bearing or other part which requires wet lubrication in the form of droplets.
  • Member 10 is provided with a cylindrical bore 16 which, for purposes of comparative dimensions may be considered as 0.250 inch in diameter, the drawing being to scale and about seven times actual size.
  • Bore 16 telescopically receives a pair of axially aligned inserts 18, 20 which abut at a face 22.
  • Insert 20 is provided with a pair of axially aligned slots 24, as best shown in FIGS. 2 and 3, which receive pins 26, the axis locating the ball in a predetermined position relative to the two inserts.
  • a hemispherical cavity is formed in insert 18 having a center of curvature at the center of the ball, as indicated by radius of curvature R As will be apparent, this provides a space of uniform width around the ball at the left half thereof.
  • Insert 20 is provided with a similar cavity of radius R which is the same as R but its center is displaced to the right side of the center of the ball.
  • the space surrounding this side of the ball is thus of non-uniform width and is essentially a crescent of revolution, narrowing in width in all radially outward directions until its width is finally the same as the space on the left side of the ball.
  • the two aligned cavities form a generally spherical cavity, the latter being illustratory of a preferred cavity but of course the invention is not intended to be so limited with other cavities, such as a true spherical cavity with the ball located centrally therein, being within the scope thereof.
  • an aerosol supply aperture 30 is disposed in insert 20, its axis intersecting the center of the ball, and a diametrically disposed discharge aperture 32 is disposed in insert 18.
  • a frusto-conical chamber or entry mouth 34 joins bore 14 and aperture 30 which serves to eliminate extreme turbulence and provide a smooth transition and velocity increase as the aerosol flows into orifice 30 with substantially no reclassification occurring therein.
  • aerosol enters the spherical cavity and im inges with some turbulence upon the center of the rig t side of the ball and spreads outwardly in all radial directions.
  • This impingement and turbulence at the right side of the ball wets it depositing an oil film thereon.
  • the drag of the flowing air on this film moves it to the left side of the ball and as the air stream approaches the discharge orifice it, in the embodiment illustrated, increases in velocity due to the continued decrease in cross section.
  • the stream picks up droplets (reclassified particles) which have coalesced on the left side of the ball, carrying same through the discharge orifice in the form of a fog with oil particles larger than those of the aerosol entering aperture 30.
  • the reclassification rate may be varied by varying the diameters of the supply and discharge orifices without dimensional change of the ball and cavity in which it is disposed. Also, the shape of the The classification capacities of the two embodiments follow wherein BI signifies bearing inch, a measure of lubrication requirement.
  • An oil aerosol reclassifier for coalescing oil particles suspended in an air stream into discrete droplets for use in lubricating parts of moving apparatus comprising:
  • a body member having a generally spherical chamber therein
  • the construction and arrangement being such that aerosol impinging on the upstream surface of the ball member forms an oil film thereon which flows by frictional drag produced by air flow around the ball member to the downstream surface thereof from which it is picked up by the flow in the form of discrete droplets for delivery through the discharge orifice.
  • An aerosol reclassifier in accordance with claim 1 wherein said ball member is supported in position by a pin having diametrically disposed ends, the axis of which is disposed transversely to the axis of the supply and discharge orifices, and about which said film may flow.
  • An aerosol reclassifier in accordance with claim 1 wherein the velocity of the air around the downstream surface of the ball member increases as it moves toward the discharge orifice thus aiding in picking up oil disposed thereon.
  • An aerosol reclassifier in accordance with claim 1 wherein said spherical chamber is formed of two parts having abutting ends, a substantially hemispherical cavity in each, the two cavities being aligned to form the generally spherical cavity.
  • An aerosol reclassifier in accordance with claim 6 wherein the two parts are provided with cylindrical outer surfaces and adapted to be fitted within a cylindrical bore of a member adapted to be secured to an aerosol supply conduit.
  • a substantially conical transition counterbore disposed between the supply conduit and supply orifice, the counterbore adapted to increase the velocity of the aerbut without any substantial reclassification therein.
  • An oil aerosol reclassifier for coalescing oil particles suspended in an air stream into discrete droplets for use in lubricating parts of moving apparatus comprising:
  • a baffle member disposed within said chamber and means supporting same therein in a fixed position relative to the body member to form a space therearound,
  • said wall having a surface formed by a first generatrix rotated about a reference axis, whereby all sections thereof in planes perpendicular to said axis are circular, said generatrix intersecting said axis at its ends and having a maximum radius at a point intermediate thereof to provide a divergent upstream surface portion between one end and toward the maximum radius and thence a convergent downstream portion toward its other end,
  • said baffle member having an outer surface formed by a second generatrix rotated about said reference axis, whereby all sections thereof in planes perpendicular to said axis are also circular and the distance between its outer surface and said wall at any section in a plane perpendicular to said axis is uniform, said second generatrix also intersecting said axis at its ends and having a maximum radius at a point intermediate thereof to provide a divergent upstream surface portion between one end and toward its maximum radius and thence a convergent downstream surface portion toward its other end,
  • a discharge orifice communicating with said chamber at a position along said axis and so oriented to receive aerosol flowing inward around tg downstream surface portion of the baffle msw I i Q th t u tio a artaaaqusntb i
