Patented July 26, 1938 , 2,124,526 ' UNITED STATES PATENT OFFICE I Albert H'. Goldsworthy, Canton, Ohio, assignor I ` to The Timken Roller Bearing Company, Cali ton, Ohio, a corporation ~of Ohio Appiicanon April 2z, 1937, serial No. 138,291 5 Claims. My invention relates to a closure for the end of a roller bearing and has for its principal object a closure which is elïective but of simple construetion and which can be used to make a self-con- “ 5 tained assembly of the bearing.' Theinvention consists principally in a closure having spaced outer cover rings and spaced inner cover rings arranged in alinement with each other and an annular washer or diaphragm bridging 10 the gap between two sets of cover rings and with its ends held between the cover rings of the re spective sets. The invention further consists in the bearing closure and in the parts and com binations and arrangements'of parts Hereinafter 15 described and claimed. ' In the accompanying drawing, Fig. l is a sectional view of a bearing and of 20 (clv. zas-1) ` ber so as to accommodate irregularities of manu facture andvarlatio ns in the sizes .o_f parts. In the construction shown in Fig. 2, >there is a center ring 20 of the same construction as the outer cover rings» 1, spacer rings 8 on either side of said center rings spacing it from the outer cover rings. Similarly there is an inner center ringI 2| in the inner ring assembly -in ,alinement with the outer center ring 20. There is thus pro vided a second ann ular chamber 22 in which a second diaphragm 2 3 is mounted. .In the construction shown in Fig. 3, the spacer rings are eliminated, the cover rings 30 being of Vangular section with nested peripheral portions 3I and radial ilanges 32. 'I'he overlapping edge portions 33 of the peripheral flange portions of the cover rings are spun over the inside rings to closure therefor embodying my invention; hold the parts in assembly. Fig. 2 is a sectional view of a modified closure; Fig. 3 is a sectional view of another modifica The modification shown in Fig. 4 includes an outer cover 40 having~ radial ilanges 4I at its ends, a center ring 4 2 mounted therein and spacer tion; and ` ' ' 15 , Fig. 4 is a view of another modification. rings 43 holding the center ring 42 in position.> In Fig. 1 is illustrated a taper'roller‘bearing Y The outer cover ring initially has a radial iiange including a cup I vor outer bearing member, conical at one end only, a projecting cylindrical portion 5 rollers 2 and a cone 3A or inner bearing member 44 indicated >in dotted lines being spun over after having a thrust rib 4 for the rollers at its large the center ring and spacer rings have been end and. having a cylindrical- ‘portion 5 extending mountedy to form the second radial ilange. beyond the small end of the raceway. The inner member ot the closure likewise in The cup has a rabbeted portion 6 in the end cludes an inner cover 45 having radial end iianges 30 opposed to the cylindrical portion 5 of said cone. 46, a center ring 41 mounted in said inner cover Mounted in said rabbet B are radially disposed and spacer rings 48 on either side of said center ñat outer cover rings 1 or washers having a spacer rings. One ilange of said inner cover 45 is formed ring 8 therebetween, the ring assembly being held by spinning over a cylindrical portion 49, shown in together by means of rivets 9. The innermost dotted lines, after the parts have been assembled. ‘ The above describ ed closures make of the bear 35 outer cover ring 1 abuts against the shoulder I0 formed by the rabbet 6 and the outermost outer ing a self-contained unit. The closure is simple cover ring 1 is ilush with the edge of the cup I. in construction, can be made cheaply of stamped The spacer ring 8 is relatively narrow and dis parts and forms a very eiïective seal. . Obviously posed between the outer portions of the cover ’ numerous changes may be made without depart rings 1. l ing from the invention and I do not wish to be Mounted on the cylindrical portion 5 of the limited to the precise construction shown. What I claim is: bearing cone 3 are :tlat inner cover -rings II or 1. A bearing closure comprising outer spaced washers and a spacer ring I2 therebetween, -the 45 ring assembly being held -together by means of radial~ cover rings, securing means therefor, inner rivets I3. The inner cover rings Ilyare in aline? spaced radial cover rings in alinement with the ment with the respective outer cover rings 1, respective outer cover rings and spaced radially there being an annular gap I4 between the outer therefrom, securing ,means for'said inner rings, peripheries oi' the inner cover rings and the inner and a floating diaphragm bridging the gap be 50 peripheries of the outer cover rings. Disposed in tween the inner and outer sets' of cover rings, the annular chamber i5 formed by the outer with its outer peripheral portion disposed between cover rings 1,'the inner cover rings I I, the outer the outer cover rings and its inner peripheral por spacer ring- 8 and the inner spacer ring I2, is an tion disposed between the inner cover rings. 2. A bearing closure comprising outer spaced annular diaphragm I6 or washer. 'I‘his `dia radial cover rings, _a spacer ring therebetween, gg phragm I6"is of asize. to‘flt loosely in saidl cham ' rivets securing said cover rings and spacer rings 55 ` \ 2,124,596 2 together, inner spaced radial cover rings in aline ment with the respective outer cover «rings and spaced radially therefrom, a spacer Aring between ' lar outer cover rings having their peripheral por tions nested and their radial flanges spaced apart, a pair of angular inner coverrings having their peripheral portions nested and their radial flanges spaced apart and radially alined with theA radial said inner cover rings, rivets securing said inner cover rings and spacer rings together, and a i‘loat flanges of said outer cover rings and an annular ing diaphragm bridging the gap between the inner l ñoating diaphragm bridging the gap between in and outer sets of cover rings, with its outer ner and outer cover rings, its outer periphery be-` peripheral 4portion disposed between the outer ing disposed between said outer 'cover rings ‘and ` cover rings and its inner peripheral portion dis. its inner periphery between said inner cover 10 posed between the innercover rings. 3, A bearing closure comprising aiplurality of outer spaced radial cover rings, spacer rings be tween adiacent cover rings, rivets securing the ring assembly together, a plurality of inner spaced radial cover rings in alinement with the respec tiveouter cover rings and spaced radially there from, spacer rings between adjacent inner cover rings, rivets securing said inner ring assembly to gether, and ñoating diaphragms bridging the gap between the inner and outer sets of cover rings. with their outer peripheral portions disposed be tween vouter cover rings and their inner peripheral portions disposed between inner cover rings. 4. _A bearing closure comprising a pair of angu rings. ‘ 5. A bearing closure comprising an outer cover v- . having a cylindrical body and radial end flanges, a center ring in said body, spacer rings' between said center rings and the inner faces of said end 15' flanges, an inner cover having a cylindrical body and radial end ilanges alined with said end flanges oi' said outer cover, a center ring in said inner cover body, spacer rings between said inner center ring and the end flanges of said inner cover andl annular diaphragms in the chambers vformed by said center rings and the respective end flanges yand spacer'v rings.
