' l ILLINOIS, A CORPORATION OF DELAWARE JOURNAL BEARING Application filed November 2, 1927. `Serial No. 230,429.
This invention relates to improvements in journal bearings.
An object of the invention is to provide a ball bearing arrangement, more particularlyT 5 adapted for use in connection with journal boxes and journals of `railway cars', and wherein means are associated with the journal and vjournal H boxes to provide races for a plurality of annular series of balls, said races and balls being so arranged as to place the balls of one series at one side of the journal and the balls of theother series at the opposite side ofthe journal under load at all times, and to provide a simple construction V; wherein a minimum number of parts `are utilized.
Other and further objects of the invention will more fully and clearly appear from the description and claims hereinafter fol- 20. lowing. 4
`In the drawings forming a part of this specification, Fig. l is a side elevational view of a fragment of a railway car truck, showing a truck pedestal member and the journal box embodying the invention mounted in said pedestal member. Fig. 2 `is a transverse vertical sectional view corresponding substantially to line 2-2 of Fig. l, and Fig. 3 is a vertical sectional view corresponding subv stantially to the line3-3 of Fig. 2.
As shown in the' drawing, 10 represents a fragment of the body'portion of the car truck, and llrepresents a common type of pedestal member mounted thereon, having the usual spaced jaws, between which is slidably disposed a journal box 12, in connection with which the invention is utilized. The numeral 13 indicates one end of an equalizer bar which bears upon the top of the journal box 4U 12, and transmits the load from the frame of the truck to the top of the journal box, which,
in turn, transmits the load to the axle.
The journal box comprises side, top, bottom and rear walls, and is of hollow construefor the reception of packing material 17. The top wall of the journal box A is provided with the usual spaced flanges l8-18, and an equalizer seat 19 for the reception of the grooved end of the equalizer bar 13. The
side walls of the journal box are also provided with spaced flanges indicated at 20-20, the latter flanges being adapted to fit upon the opposite sides of the pedestal jaws to provide guides in the usual manner, the journal box 12 being retained in its position between the jaws of the pedestal member by the usual strap 21. Mounted in the annular recess 14 of the journal box, is a race member 22 in the form of a ring having a base portion 23, which bears upon the wall defining the annular recess 14 of the journal box. Formed integrally with the base portion 23, is an inwardly extending centrally formed web 24, the inner extremity of which terminates in a portion providing laterally extending flanges 25 and 26. The iange 25, at its inner side, is provided with an annularly extending bear-A ing surface 27, inclined toward the journal 15. The outer side of the flange 25 is provided with an annularly extending bearing surface inclined oppositely to the bearing sur face 27, as best shown in Fig. 2. The flange 26 is provided with inner and outer annularly extending bearing surfaces 29 and 30, of the same character as the bearing surfaces 27 and 28, but being oppositely disposed with reference to the latter. f
The journal 15 is providedwith an annular shoulder 31, a cylindrical portion 32, and a reduced threaded end portion 33. Mounted upon the cylindrical portion 32 are the race members 34 and 35. The race member 35 comprises a peculiarly formed ring having a vertically extending web 36 and inner and outer integrally formed flanges 37 and 38. Theflange 37 on its inner surface is provided with a V-shaped groove so arranged as to define bearing surfaces 39 and 40 adapted to engage the balls of the annular series of balls indicated at 41, interposed between the bearing surfaces 39 and40, and the bearing surface 30 of the flange 26, the angles of the bearing surfaces 39 and 40 being so disposed that the points ofcontact thereof `with the Surfaces of the related race member, one of said race members bearing against the annular shoulder of said journal; and resilient means mounted on said journal and bearing on the other journal race member for urging the latter and journal box race member toward the first journal race member.
5. In an anti-friction bearing of the character described, the combination with a journal box and a journal having an annular shoulder thereon and a reduced end portion; a race member mounted in said journal box and provided with an inwardly disposed radial web terminating in laterally extending flanges, the inner and outer surfaces of said ianges being inclined toward each other and providing race ways; race members mounted on said journal and disposed at opposite sides of said flanges, each of said race members being provided with connected flanges each having a bearing surface arranged adjacent a race way of one flange; annular series of balls interposed between the race ways of each of said ianges and the adjacent bearing surfaces of the related race member, one of said race members bearing against the annular shoulder of said journal; and resilient means mounted on said journal and bearing on the other journal race member for urging the latter and journal box race member toward the other journal race member, the race ways of said flanges and the bearing surfaces of said journal bearing members being inclined so that the bearing points of said balls with said race Ways and bearing surfaces, when projected, intersect the longitudinal axis of the journal at a common point.
6. In an anti-friction journal bearing, the combination with a journal member and a journal box open at the outer end; of two series of annular bearing elements having rolling movement; and means for transmitting the load from the journal box to said journal simultaneously through the bearing elements of one of said annular series at one side of the journal and through the bearing elements of the other annular series at the opposite side of the journal, said means including detachable race members mounted j on the journal member and within the journal box respectively, said detachable members being insertible and removable through said open end of the journal box.
7 In an anti-friction bearing, the combination with two members, one of which is rotatable with reference to the other; of inner and outer annular series of anti-friction elements having rolling movement, said inner and outer annularseries being interposed between said members, the annular path of movement of said inner series being of lesser diameter than the path of annular movement of the outer series; means having bearing engagement with the inner and outer series of
