Definitions

  • This invention relates to an oil dipper for automatic lubricating boxes of bearings having an oil bath wherein the ends of the dipper extend.
  • the dippers hitherto used in boxes of the said type have had the form of a plate bent in a suitable manner, the ends of the dipper usually having had a general rectangular or trapezoidal shape and having been provided with or without dripping points to insure delivery of the oil to the parts to be lubricated. It has, however, been noticed that under certain conditions, it was difficult to obtain sufficient lubrication, these conditions depending on the one hand on 'the nature of the lubricant and onthe other hand on the speed of rotation of the dipper.
  • the present invention has for its general object to provide adipper which will insure, under all conditions, copious lubrication to the Ibearing.
  • adipper which will insure, under all conditions, copious lubrication to the Ibearing.
  • the dripping edges of the two opposed ends of the dipper are substantially perpendicular relatively to each other.
  • Fig. 1 is a front elevation of an oil dipper constructed in accordance with one embodiment of the present invention.
  • Fig. 2 is a side elevation of the structure shown in Fig. 1.
  • Fig. 3 is an enlarged detail view of one side portion of a dipper of the type shown in Figs. 1 and 2, illustrating a slight modification.
  • Fig. 4 is a side elevation of the structure shown in Fig. 3.
  • Fig. 5 is a view similar to Fig. 3 another slight modification.
  • Fig. 6 is a view similar to Fig. 3 illustrating a further modification.
  • the dipper comprises a main part or bod 10, the end portions of which are extended laterally as at 11 and then outwardly parallel to the plane of the body to provide the clipping members indicated as 12, 12.
  • One of the members 12 has a general rectangular form or shape while the other has the general form or shape of a segment-
  • the outer curved edge 13 of the segmental 'member 12 has as its center the axis,
  • this dipper when the same does not rotate with sufficient speed to cause oil adhering to its faces to be projected therefrom under the action of centrifugal force, is as follows: Assuming that the dipper rotates in the direction of the arrow 1'7, a stream of oil flows from the segmental dipping part 12 from its point 18 beginning at the time said dipping part leaves the bath of oil 0 in the bottom of the journal box B and until the median plane of the dipper reaches substantially the vertical position shown, the oil under the combined action of gravity and centrifugal force flowing towards the said end point 18 of the dipping member.
  • the dripping is produced from this moment and in the same manner along the edge 14 disposed between the end 18 and the point 19 in the form of a regular stream, until the median plane of the dipper reaches substantially a horizontal position.
  • the regular stream flowing along the edge 14 is obtained on account of the perpendicular position of this edge relative to the median plane of the dipper and the proportions of the dipping surface, taking into consideration the time necessary for the lubricant to flow by gravity along them and to reach the edge l819 at relatively low speeds of the dipper.
  • the dipping part 12' at the other end of the dipper functions in an entirely different manner.
  • the oil stream first is discharged from the outer trailing corner.
  • the discharge takes place from some point along dripping edge 14, and the point of discharge reaches the inner trailing corner of 14 when the dipper approaches the vertical position.
  • centrifugal force drives the oil towards the circumference of 12, and at a certain critical speed or speed range very little oil is discharged from the dipper onto the bearing.
  • each dipping part has a critical speed
  • the two critical speeds do not coincide, due to the different shape and arrangement of the dripping parts 12, 12'. Therefore, an un interrupted flow of lubricant at all speeds is assured.
  • the form or shape of a segment as shown in Figs. 1 and 3 it may be given another form or shape, for instance, the form of a triangle 20 as shown in Figure 6, the base edge 21 of this triangle forming in this case a dripping edge disposed perpendicularly with relation to the median plane of the dipper.
  • the lateral ends of the triangle may, for instance, be intersected as indicated by broken lines 22.
  • the bent part 11 of the dipper may be disposed at right angles with relation to the body 10 thereof as shown in Figure 4, or it may be inclined relatively to the said body so as to form between the parts 11 and 12 an acute angle constituting a drip, as shown in Fig. 2.
  • the dippers as described above are very easily made since they may be cut or stamped from thin plate, the thickness of which is determined by the dimensions of the dipper while taking into consideration that the latter must not be deformed in any way even at high speeds.
  • a triangular notch 23 may be provided in the outer edge 13 of the segmental dripping part 12 as shown in Fig. 3 so as to form two points 24 adapted to facilitate the projection of the oil under the action of centrifugal force.
  • edges'of the dipper may be partially or completely beveled.
  • segmental dripping part 12 may be used at both ends of the body 10. That is to say, both arms of the dipper may be in the form of segments, the dripping edges of which are substantially perpendicular to the median longitudinal line of the dipper.
  • a dipper adapted to be secured to an axle for rotation therewith to dip into oil in an axle box and to elevate and deliver oil to the'axle bearing, and dipping members at the ends of said dipper, respectively, each having a dripping edge, the dripping edge of each member being disposed at substantially right angles to: the dripping edge of the other member.
  • a dipper adapted to be secured to an axle for rotation therewith to dip into oil in an axle box and to elevate and deliver oil to the axle bearing, and dipping members at the ends. of said dipper, respectively, each having a dripping edge, the dripping edge of each member being disposed at substantially right angles to the dripping edge of the other member, one of said.
  • one of said members having the general form or shape of a segment, the center of the curved edge of which is coincident with the center of rotation of the dipper.
  • a dipper adapted to be secured to an axle for rotation therewith to dip into oil in an axle box and to elevate and deliver oil to the axle bearing, and dipping members at the ends of said dipper, respectively, each having a dripping edge, the dripping edge of each member being disposed at substantially right angles to the dripping edge of the other member, one of said members having the general form or shape of a triangle.
  • a dipper adapted to be secured to an axle for rotation therewith to dip into oil in an axle box and to elevate and deliver oil to the axle bearing, and dipping members at the ends of said dipper, respectively, each having a dripping edge, the dripping edge ofeach member being disposed at substantially right angles to the dripping edge of the other member; said dipping members being laterally offset with respect to the body portion of the dipper so as to extend across the end of the bearing.
  • a dipper adapted to be secured to an axle for rotation therewith to dip into oil in an axle box and to elevate and deliver oil to the axle bearing, and dipping members at the ends of said dipper each having a dripping edge, the dripping edge of, one of said members being disposed at substantially right angles to the longitudinal axis of the dipper, and the dripping edge of the other member being disposed substantially parallel to the longitudinal axis of the dipper.
  • a dipper adapted to be secured to an axle for rotation therewith to dip into oil in an axle box and to elevate and deliver oil to the axle bearing, comprising a body portion, dipping members at the ends of said body portion laterally ofiset with respect thereto, one of said dipping members being in the form of a segmental plate having an outer curved edge and an inner straight dripping edge disposed at substantially right angles to the longitudinal axis of the body portion, the other of said dipping members being of substantially rectangular shape and having side dripping edges disposed substantially parallel to the longitudinal axis of said body portion.
  • a rotatable dipper of the class described comprising a body portion having a plurality of angularly related radial arms, said arms having dipping members of difierent shapes, the dipping member of at least one of said arms having its dripping edge disposed substantially parallel to its direction of motion, and the dipping member of at least one of said arms having its dripping edge disposed substantially perpendicular to its directionof motion.
