Description

AXLE BEARING LUBRICATION DEVICE Filed May 9, 1934 Patented Feb. 11, 1936 UNITED STATES PATENT OFFICE AXLE BEARING LUBRICATION DEVICE Application May 9, 1934, Serial No. 724,805 In Germany March 17, 1934 1 Claim.
Oil delivery plates for axle bearing lubrication means of elongated shape are known, the side edges of which are arranged in radial direction towards the pivotal point of the delivery rod.
l The amount of oil delivered, however, is unsatisfactory, especially in the middle range of speed of 30-80 revolutions. Also, delivery plates are known, the surfaces of which are provided with ribs parallel to the throwing edges in order to 10 delay the throwing off of the oil at higher speeds by producing an artificially lengthened path of movement of the oil.
The arrangement according to the invention will combine. such a rib arrangement with latera1 running off edges arranged at about 60 to the axis in such a manner that the ribs at their ends near these sharpened running off edges are bent over so as to extend in the same way as the upper corners of the plate and open into the 20 running ofi edges forming points in their lower part. At the same time the running off edges at their upper ends are to be connected with the throwing edge of the plate over the strongly rounded corners.
25 The object of this arrangement is, especially in the lower and middle speed range of.15-90 revolutions, to cause the oil carried along with the plate in the oil bath to be given up at the catch troughs by dropping off in a more com- 30 plete manner than in the known plates.
The drawing illustrates a constructional example of the arrangement according to the invention. Fig. 1 being an elevation of the delivery plate from its broad side and Fig. 2 a section through the delivery plate in the plane of axis.
In the figures a indicates the ribs, b their lat- 5 eral bends, c the throwing edge of the plate, at r the upper strongly rounded corners, e the lateral running off edges and their lower dropping points.
The improved delivery action of this form of plate depends on the fact that the oil carried along by the throwing edges and the channels between the ribs in the oil bath runs during the upward rotation of the plate as far as the bends on the downwardly directed corner and is there diverted in order, during the passage of the plate over the trough, to be given up at the sharpened rear running off edge in the form of a train of drops on to the bearing members.
What I claim is:
An oil delivery plate of elongated shape, for axle bearing lubricating means, more particularly for rail vehicles, having ribs on its surface, a throwing edge, and running off edges which are inclined at an angle of about 60 to the axis of symmetry of the plate and are sharpened and run out into a dripping point, the throwing edge being curved at its ends to meet the running ofi edges, forming rounded upper corners of the plate, and the ribsalso beingcurved at their ends like the throwing edge.
