Definitions

  • the feed blades having the shape of segments of 10 a ring and enlarged in the form of a T over the Width of the rod-shaped center piece.
  • inner edge of the feed blades which faces the axis of rotation, extends over the feed rod in a length corresponding to at least one half of the width of the feed rod, and. the inner edges of the feed blade, which extend over the feed rod, have with increasing distance from the center of the feed blade a decreasing distance from the axisof rotation.
  • Feeding members designed according-to the invention have the special advantage that 'ow ing to the peculiar shape or form'of the feed blade, the lubricant taken up by the feed blade during its passage through the store of lubricant reaches the inner edge of the feed blade when the feed blade. has reached the highest point of its path of rotation and is located above the collecting member for the'lubricant.
  • This collecting member is usually formed from.
  • the bend of the feed rod may be; as shown, a less distance from the axis of rotation than the inner edge of the feed blade facing the axis The V bounding edges.
  • the feed blade may be kept very thin and provided with sharpened edges.
  • the feed rod must be 'comparatively strong 'to take up the centrifugalforces of the feedbladeso that should it pass through the store of lubricant it produces a strong emulsification, oxidation and premature aging of the lubricant.
  • the passage of the feed rod through the store of lubricant was hitherto unavoidable if the whole feed blade had to dip into the store of lubricant. According to the present invention, the dipping of the whole feed blade is effected without it being necessary for the feed rod to dip into the store of lubricant.
  • the feed blades are constructed as polygons andthe arrangement of the corner points of the polygons, differs according to the diiferent feed blades, there results therefrom the advantageous feature that the feed blades cannot assume at certain speed of the axle journal critical states ofequilibrium to which the feed of the lubricant-is subjected.
  • These critical states of equilibrium are produced by the fact that the forces causing; the separation of the lubricant and keeping it against the feed blade can maintain points thev bounding, edges of the feed blades have a different distance from the center of rotation and .a different length so that the centrifugal for' ces'j arenever the same at these
  • the critical conditions of equilibrium cannot occur at the same time in con-v nection with both the feed blades.
  • Fig. 1 showing a side elevation of the oil feed rod
  • Fig. 2 represents a front elevation of the same.
  • Fig. 3 shows in vertical longitudinal section blades.
  • the axis of rotation is gradually reduced toward" the inner apices I8, I9 and 20, 2
  • the feed blades are consequently cut back in the direction of rotation at 3, 4, Eand 8 drip-tips I, 8, 9 and It being formedsand the surface of the feed blade beingperpendicular to the rod-face I I, I2 supporting the feed blade
  • the rod-support I3 itself, which may be firmly connected by way of holes 24 with the axlejournal which is not illus-' trated, possesses at I5 and I6 outwardly arched portions which enable a catching member, which is shown in Fig. 3, to be located within rangeof the drippings and threads formed by the feedmember. As. is noticeable particularly from the lower parts of Figs.
  • the whole of the feed blades I and 2 together with the drip-tips I-IIl can consequently be dipped into the lubricant store I I without the parts II and I2 of the rodsupport, that is the rod-support I3 as such, requiring to dip into the lubricant store. Nevertheless fully developed drip-tips are formed, which cause the lubricant to dripoff with certainty.
  • the lubricant store is consequently traversed only by the feed blades, withoutit being lashed up, emulsified and oxidized.
  • Figs. 1 and 2 show that the feed blades are constructed as narrow segments of a ring, so that the paths along which the lubricant slips, measured in the radial direction, are shorter than the paths, along which it is drawn, measured in the peripheral direction.
  • This is worthy of consideration in so far as in consequence of forces of inertia arising in the case of an insufficient ratio between'the paths along which the lubricant is drawn and those aiong which it slips the lubricant is discharged from the feed blades before the latter have reached their position above the collecting member; the lubricant consequently passes back unused into the lubricant store, while lubricant is supplied insufficiently to the bearing surface.
  • Fig. 2 shows that the realization 0f a satisfactory relationship is possible without the fulfilment of the other requirements being disturbed.
  • edges I, 1", 8', 8", 9', 9'', ID, ID", 22 and 23 are formed as knife-edges in a manner well known per se, in-order to prevent air from being driven into the lubricant store.
  • the moistened surface. of the feed blades may have a constant ratio to the surface ofthe axle-journal, independently of the diameter of the axle-journal, lies. within the scope of the invention.
  • Theprinciple of the invention is also realized when the faces of the rod-support carrying the feed blades are not perpendicular to the face of the feed blade but are at an oblique angle to the same.
  • An axle bearing comprising an axle box housing, a bearing brass adapted to receive an axle journal, a lubricant store in said housing, feeding a means adapted tolift lubricant from said lubricant store, saidfeeding means comprising a rodshaped center piece, feed blades on said center piece, said feed blades designed as segments of .a ring and, extending T-shaped across the rodshaped center piece of said feeding means, acollecting member for the lubricant in the annular space swept over by the said feed blades during the rotation of the feeding means, said rodshaped center piece bent aroundsaid collecting member, said bend being at a shorter distance from the axis of rotation than the inner edge of the feed blades facing the axis'of rotation.
