Abstract

In certain environmental circumstances, such as evaporators, it is desirable to employ bearings having the ability to operate in a vacuum without contaminating lubricants. The bearing illustrated in the drawings may be subjected to equal radial and end thrust loading without employing lubricants.

No Lubricant Roller Bearing

In certain environmental circumstances, such as evaporators, it is desirable to employ bearings having the ability to operate in a vacuum without contaminating lubricants. The bearing illustrated in the drawings may be subjected to equal radial and end thrust loading without employing lubricants.

Referring to the drawing, a bearing 10 having, in the present instance, tapered rollers 11A, 11B located in sets of three or more, each set opposing one another, is illustrated. The bearing includes an outer ring 12 having a circumferentially extending interior, upper and lower sloped face portions 13 and 14, respectively, meeting at an apex 15. The roller keeper or case 18 includes an upper inner ring 16 and a lower inner ring 17, each of the rings having a sloped circumferentially extending peripheral extremity 16A and 17A confronting, respectively, the surfaces 13 and 14 of the outer ring.

As illustrated best in Figs. 2 and 3, the tapered rollers of each set, 11A and 11B, are preferably positioned so that the roller rides against opposing sloped surfaces. For example, in Fig. 2 the rollers of the set 11A ride in rolling engagement against the surfaces 17A and 13, while in Fig. 3 the rollers of the set 11B ride against the surfaces 14 and 16A. To maintain the relative circumferential position of the rollers, connected to the roller keeper or cage 18 are keeper bars 19 and 20 which project radially outward toward the apex 15. The upper and lo...
