3 Claims.
This invention relates to journal boxes and more particularly pertains to means for mounting an oil conveying member on the end of the journal in such a manner that the shocks that are normally transmitted from the journal to the member are cushioned by a layer of oil between the member and the adjacent end of the journal upon which it is mounted.
When mounted on the end of the journal in the usual manner without provision for cushioning movement, shocks resulting from the wheel going over rail joints, crossings and the like and from wheel shell-outs and flat spots, are transmitted from the car wheel through the journal to the oil conveying member. As a resuit the member vibrates and in the course of time fails due to fatigue of the metal. This failure may partially or completely stop delivery of oil from the reservoir in the bottom of the box to points where it normally would be delivered to the bearing surfaces of the journal and bearing members and may ultimately result in a hot box.
While it is customary to secure the oil con veying member on the journal so that it is substantially immovable with respect to the journal, it has been found in practice that some movement always is present. I have found that by providing a layer of oil between the oil conveying member and the journal that it is possible to cushion this transverse movement of the member and substantially reduce the vibrations transmitted to the member.
In the accompanying drawing:
Figure 1 is an end view of a journal box embodying my invention, with certain parts cut away to disclose more clearly important features thereof.
Figure 2 is a longitudinal sectional view, the section through the oil conveying member being taken on line 2-2 of Figure 1; and
Figure 3 is a partial view of the inner side of the oil conveying member.
Referring to the drawing, the journal box I0 receives a journal ll upon which is supported a bearing member l2. Between the bearing member and the top of the journal box is a wedge member l3. An oil conveying member 14- mounted on the front of the journal is adapted to dip into an oil reservoir l5 at the bottom of the box and carry oil to the upper part of the box where it either drops into a trough IE or is thrown by centrifugal force onto the inner wall I! of the box, where in either case it is conveyed through suitable passages to the contacting surfaces of 55 scribed or portions thereof, but recognize that the bearing member l2 and journal ll. The oil conveying member comprises a central portion 18 and radially extending arms l9 and 20 which are suitably shaped to carry oil from the reservoir to the upper part of the box, as has been previously described. The central portion ill of the oilconveying member comprises apair of spaced walls 2| and .22 joined .by a cylindrical wall 23. Extendingaxially inwardly from wall 22 is a lip 24 that overlaps collar 25 on the end of the journal. The inner wall of lip 24 is normally spaced from the outer surface 26 of collar 25 so that the oil conveying member can move radially a limited amount with respect to the journal. Retaining bolts 2'! pass through openings 28 in bosses 32 formed on portion I8 and these openings are slightly larger than the bolts so as to allow the aforesaid movement of the oil conveying member. Lock-washers 29 may be provided to prevent the bolts from loosening.
As the journal rotates during movement of the car an abundant supply of oil is deposited in trough I6 and this supply is not only suflicient to lubricate the bearing surfaces on the journal and bearing member but also flows over the collar of the journal and works its way into the space between lip 24 and surface 26 of the collar. Oil
also is splashed through opening 30 in wall 2| and opening 3| in wall 22 and works its way between the inner face of wall 22 and the end face of collar 25 into the space between lip 24 and surface 26. Openings 33 and 34 in bosses 32 permit oil to flow into the spaces between the bolts and the bolt holes of the oil conveying memher. This oil layer between lip 24 and surface 26 and between the bolts and the walls of the bolt holes is sufficient to cushion the shocks transmitted from the journal to the oil conveying member and materially reduces the vibration of the oil conveying member. This has resulted in a considerable increase in the life of the memher before it fails from fatigue of the metal.
If desired, oil grooves 35 may be cut in the various modifications are possible within the scope of the invention claimed.
What I claim is: 1. In a journal box, a journal extending therein, an oil reservoir, an oil conveying member on the end of said journal adapted to rotate therewith and convey oil 'from said reservoirto the upper portion of the box, said member having a central portion for mounting said member on the end of said journal, said portion comprising around said securing means, said oil in said pocket and around said securing means being adapted to cushion said transverse movement of said member.
2. In a journal box, a journal extending therein, an oil reservoir, an oil conveying member on the end of said journal adapted to rotate therewith and convey oil from said reservoir to the upper portion of the box, said member having a central portion for mounting said member on the end of said journal, a flange on said portion extending into overlapping relation with the end of said journal and spaced therefrom to form a pocket adapted to receive oil from said member, said central portion having an opening extending therethrough and a channel in said central portion adjacent the end of said journal extending from said opening to said flange for conducting oil that is thrown into said opening tosaid pocket.
3. In a journal box, a journal member extending therein, an oil reservoir, an oil conveying member on the end of said journal member adapted to rotate therewith and convey oil from said reservoir to the upper portion of the box, said oil conveying member comprising a central portion adapted to engage the end of said journal member, a flange on one of said members ex tending into overlapping relation with the other of said members and forming an oil receivin pocket therewith, said central portion having an opening adapted to receive oil thrown by said oil conveying member, and a channel between said members extending from said opening to said pocket for conducting oil to said pocket.
