ma a the January 16, 1am. Serial No. 812,469.
The present invention relates to ball bear ifngs, and more'particularly to a cage there- One of the objects of the invention is to provide a cage containing a plurality of ball retaining devices which are, carried by a common support'and constructed in such a manner that they can be attached to-such;
support, to constitute with the balls retained and separated thereby an assembled-unit.
- Another object of the invention is to pro vide a :device of this type which is simple in construction, efii cient in operation, and which can, be applied both tojournal bearings and step bearings.
A further object of the invention is to produce a cage, the individual 'ret-aining*members of which are constructed and disposed in such a manner that they are adapted to hold in proper position relative to each other a lurality of rows or sets of balls.
ith these and other objects in view,
which will more fully appear as the nature of the invention is better understood, the} same consists in the combination, arrangement and construction of parts hereinafter fully described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and propor: tion of the several parts and details of construction within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.
A few of the many possible embodiments of the invention are illustrated in the accompanying drawings, in which 2 Figure 1 is a central vertical section taken through a ball bearing constructed in accordance with the present invention; Fig. 2 is a section taken on line 22 of Fig. 1', partly in elevation; Fig. 3 is a front elevation of one of the retaining elements of the cage; Fig. 1 is a side elevation thereof; Fig. 5 is a section taken on line 5-5 of Fig. 4; Fig. 6 is a vertical section taken through a portion of a modified construction; Fig. 7 is a plan view, part1 in elevation, of a step bearing constructe in accordance withthe present invention;.Fig, 8 is as'ection taken on line 88 of Fig. 7 and'Fig. 9 is'a lan view of one of the retaining elements o the bearing shown in Figs. 7 and'8I Referrin now more particularly to Figs. 1 to 5, inc usive; the numeral lOindicates the inner bearing ring, having a bore 11, by
proved manner" to an aitlecr shaft. This ring is provided with two raceways 12 and 13, one ,disposedbelo'wthe' other and in alinement with the raceways 14 and 15,- respectively, in an outer bearing "ring 16. Two series of balls 17 and1'8 are disposed intermediate the'bearing rings, and run in the two sets of registering raceways. The halls are spaced apart by separators, denoted by the numeral '19. Each of these separators is'made of comparatively soft material, fo'r instance brass, and comprises a plate, preferably formed by stamping, consisting of two substantially parallel wings 20, which are connected by a ring-like portion 21. The inner face of the ring-likeport-ion is concave, accommodating and'e'ncircling one of the balls 18. The outer faces of the wings 20? are also concave, the juxtaposed wings of two adjoining retainers contacting with and holding in place one of the balls 17. Each wing of a retainer is provided with an upwardly extending-lug 22., the ring-shaped portion 21 having a downwardly projecting lug, indicated at 23. The retainers are attached to supporting rings 24 and 25 by the intermediary of these lugs. The supporting rings are disposed within grooves'26 and 27 in the outer and inner bearingrings, respectively, transversely of and outside the raceways. The retainers are attached to the supporting rings by forming in the latter slots 28 and 29, respectively, the lugs 22 being seated in the slots 28, and the lugs 23 in the slots 29, both sets of lugsbeing bent upon the outer faces of the supporting rings.
To permit of an assembling of the bearing, the bearing rings are provided with recesses 30, as clearly shown in Figs. 1 and 2 of the drawings, the balls being inserted through the said recesses into the respective raceways. An oil groove 31 is provided in the outer bearing ring for a well known purpose.
It will be observed that, since the sup porting rings 24 and 25 completely inclose which said ring may be secured inany apthe annular space between the bearing rings, any possibility of dust or foreign matter entering said. annular space is effectively prevented. The retainers or separators bemg fixedly attached to said supportlng rings, will obviously hold the balls in fixed relation to each other. Inasmuch as the retainers are interconnected, the breakage of a ball does not effect materially the operation of the bearing for the reason that all other balls are kept in their proper positions.
A modification of the invention is shown in Fig. 6 of the drawings which differs from the one above described in that the retainers are attached to one supporting ring only, said rin being denoted by the numeral 32. In this case obviously the retainers lack the lugs 23. Otherwise the operation and construction of the device are in all. respects identical with those of the de-" vice described above.
X further modification of the device is shown in Figs. 7 to 9, inclusive. This form shows the invention applied to step bearings. The bearing comprises an upper ring 33 and a lower ring 34, each ring being provided with two parallel raceways 35, the raceways of the upper ring registering with those of the lower ring. The cage comprises a supporting ring 36, the longitudinal axis of which coincides with the longitudinal axes of the bearing rings, and sup orts the spacing and retaining elements 3 which are similar in construction to those described in connection with Fig. 6 of the drawings, and are attached to the ring in the same manner, the only difference being that the wings 22' of the individual retaining elements are disposed radially relative to the bearing rings; This difference, however, is not structural; it is only incidental to the relative location of the bearing rings.
What I claim is 1. In a ball bearing, the combination with an innerand an outer bearing ring, each being provided with two raceways, thereby forming two independent races for balls,
of a plurality of balls running in each race- Way, a supporting ring, and retainers attached to said supporting ring, each retainer comprising a plate having a ring-shaped portion provided with a concave inner face said raceways, and retainers attached to said supporting rings, each retainer comprising a plate having. a ring-shaped portion provided with a concave inner face encircling a ball in one of said raceways and furthermore wings having outer concave faces, the juxtaposed wings of two adjacent retainers embracing a ball in the other one of said raceways.
In a ball bearing, the combination with an inner and an-outer bearing ring, each being provided with two raceways, thereby forming two independent races for balls, of a plurality of balls running in each raceway, supporting rings disposed outside of said raceways and covering completely the annular space between said bearing rings,
and retainers attached to said supporting;
rings, each retainer comprising a plate having a ring-shaped portion provided with a concave inner face encircling a ball in one of said raceways and furthermore wings having outer concave faces, the juxtaposed wings of two adjacent retainers embracing a ball in the other one of said raceways.
4:. A cage for ball bearings comprising a rin -shaped supporting member, and retaining members attached thereto, each retaining member comprising a plate having a ring-shaped portion provided with a concave inner face encircling a ball and furthermore Wings having outer concave faces, the juxtaposed wings of two adjacent retain'ers embracing a ball.
