Description

BEARING CAGE FOR A ROLLER BEARING ASSEMBLY
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority to U.S. Provisional Patent Application No.
61/525,499, filed August 19, 2011, the entire contents of which are hereby incorporated by reference.
BACKGROUND
[0002] The present invention relates to roller bearing assemblies, and more particularly to cages used with roller bearing assemblies.
[0003] Off-highway vehicle transmissions typically use tapered roller bearings for shaft support to resist a combination of radial and axial loads. The shaft speeds are typically reasonable for a conventional design of a tapered roller bearing. It is necessary to increase shaft operational speed range to provide for both normal work operations as well as high speed transportation on roads. The high occasional speeds can exceed the bearing speed capabilities, even with adequate oil supply, and cause bearing failure. While these speeds are within the speed capability of bearings with special lubrication features, the modifications are cost prohibitive for such applications. U.S. Patent No. 4,425,011, assigned to the Timken Company, discloses a polymer cage with oil channels in the cage bridges to deliver oil to a thrust rib of the bearing assembly.
SUMMARY
[0004] In one embodiment, the invention provides a cage for a roller bearing assembly. The cage includes a first end ring, a second end ring, and a plurality of bridges extending between and connecting the first and second end rings. At least one bridge has an inner surface with a groove formed therein. The groove extends at least partially into the first end ring. The first end ring includes a capture region adjacent each groove, each capture region configured to direct lubricant contacting the first end ring into the respective groove.
[0005] In another embodiment the invention provides a roller bearing assembly including a first race having a raceway, a thrust rib at a first end of the first race and an end face at a second end of the first race. The assembly further includes a second race having a raceway. A plurality of rolling elements is positioned between the first and second races in rolling contact with the respective raceways. A cage is also provided for positioning the rolling elements. The cage includes a first end ring, a second end ring, and a plurality of bridges extending between and connecting the first and second end rings. At least one bridge has an inner surface with a groove formed therein. The groove extends at least partially into the first end ring. The first end ring includes a capture region adjacent each groove, each capture region configured to direct lubricant contacting the first end ring into the respective groove.
[0006] In yet another embodiment, the invention provides a roller bearing assembly including a first race having a raceway, a thrust rib at a first end of the first race and an end face at a second end of the first race. The assembly further includes a second race having a raceway. A plurality of rolling elements is positioned between the first and second races in rolling contact with the respective raceways. A cage is also provided for positioning the rolling elements. The cage includes a first end ring, a second end ring, and a plurality of bridges extending between and connecting the first and second end rings. At least one of the first and second end rings includes a plurality of projections extending radially relative to a central axis of the cage and engaging a groove formed in at least one of the raceways.
[0007] Other aspects of the invention will become apparent by consideration of the detailed description and accompanying drawings.

[0013] Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways.
[0014] Fig. 1 illustrates an arrangement having two conventional tapered roller bearing assemblies 10, each shown without a roller cage for clarity. The tapered roller bearing assemblies 10 support a shaft 14 onto which gears 18 are secured. A housing 22 supports and at least partially surrounds the bearing assemblies 10. The apices of each tapered roller bearing assembly 10 are directed away from the other bearing. Lubricant (e.g., oil— represented by the arrow 26) is supplied to one or both open ends of the shaft 14, and is directed radially outwardly between ends of the shaft 14 and the housing 22 toward the bearing assemblies 10 for lubrication.
[0015] The bearing assemblies 10 are substantially identical, and arranged in mirror- image relation to one another. Each bearing assembly 10 includes a first ring or race 30, which in the illustrated embodiment is an inner race (sometimes referred to as a cone). The first race 30 includes a raceway 34 that supports a plurality of rolling elements 38 therein in rolling contact. In the illustrated embodiment, the rolling elements 38 are tapered rollers. The first race 30 includes a thrust rib 42 at one end of the raceway 34 and a shoulder 46 at the other end of the raceway 34. Together, the thrust rib 42 and the shoulder 46 position and maintain the rolling elements 38 on the raceway 34, with the shoulder 46 functioning to keep the rolling elements 38 from falling out during handling of the bearing assembly 10. The first race 30 also includes an end face 50, which in the illustrated embodiment is generally aligned with an end of the shaft 14. The bearing assemblies 10 further include a second ring or race 54, which in the illustrated embodiment is an outer race (sometimes referred to as a cup). The second race 54 includes a raceway 58 that supports the plurality of rolling elements 38 in rolling contact therewith. [0016] Fig. 2 illustrates the bearing assemblies 10, each with a conventional rolling element cage 62. The illustrated cage 62 is configured as disclosed in U.S. Patent No.
4,425,011, the entire content of which is hereby incorporated by reference. The illustrated cage 62 includes an oil channel 66 on a radially inwardly-facing surface for channeling the oil 26 between the housing 22 and the end face 50 of the first race 30 toward the large- diameter end of the rolling elements 38 and toward the thrust rib 42.
[0017] Figs. 3-5 illustrate a cage 70 of the present invention for use with the bearing assemblies 10, or as will be explained in further detail below, with slightly modified bearing assemblies 10' (having like reference numerals with the indicator prime (')) . The cage 70 is designed to further enhance and facilitate lubrication of the bearing assemblies 10, 10' relative to the conventional cage 62. The illustrated cage 70 is integrally molded from a polymer, but in other embodiments, could be made of metal or other suitable materials using other fabrication methods.
[0018] Referring first to Figs. 3 and 4, the cage 70 has a first end ring 74, which in the illustrated embodiment is the smaller diameter ring adjacent the smaller diameter end of the rollers 38', and adjacent the end face 50' of the first race 30'. The cage 70 also has a second end ring 78, which in the illustrated embodiment is the larger diameter ring adjacent the larger diameter end of the rollers 38', and adjacent the thrust rib 42'. The second end ring 78 includes at least one flange 80 extending radially outward to overlap the second race 54' in the axial direction as described in further detail below. If a single flange 80 is provided, the flange 80 can extend all the way around the circumference of the second end ring 78, or alternately, along only a segment thereof. Multiple flanges 80 can be spaced as desired (e.g., equally-spaced) around the circumference of the second end ring 78. The flange(s) 80 have an axial thickness T and are spaced with an axial clearance C from the second race 54' to avoid rubbing and drag during normal bearing operation. The axial clearance C can be less than half the axial thickness T of the flange 80. A plurality of bridges 82 (only one is shown) extend between and connect the first and second end rings 74, 78. Together, the bridges 82 and the end rings 74, 78 define a plurality of rolling element pockets in which the rolling elements 38' are retained to maintain proper spacing between the rolling elements 38'.
[0019] Each bridge 82 includes a web or rib 86 that extends radially between adjacent rolling elements 38' (see Fig. 5), and that extends axially between the first and second end rings 74, 78. The rib 86 has a radially inner surface 90 (which is also an inner surface of the bridge 82) that includes a channel or groove 94 formed therein. The groove 94 extends substantially the entire axial length of the bridge 82 and at least partially into the first end ring 74. The groove 94 extends from the first end ring 74 to a location generally axially aligned with the second end ring 78 and spaced radially inwardly of the second end ring 78. The groove 94 is configured to receive and direct oil 26 from the first end ring 74, along the rib 86, and toward the thrust rib 42'. The large diameter ends of the rolling elements 38' periodically contact the thrust rib 42', and the groove 94 helps ensure that a sufficient amount of lubricant 26 reaches the thrust rib 42'. The rib 86 increases in height from the first end ring 74 toward the second end ring 78 to account for the taper in the rolling elements 38' and the first race 30'. This results in the groove 94 also defining an inclined path, with the end of the groove 94 adjacent the thrust rib 42' being radially outward of the end of the groove 94 adjacent the first end ring 74. Centrifugal force therefore drives oil 26 through the groove 94 and to the thrust rib 42' even at high rotational speeds. The groove 94 can be provided on every bridge 82, or on less than every bridge 82.
[0020] To further improve the flow of lubricant 26 to the thrust rib 42', the cage 70, and more particularly the first end ring 74, includes a capture region 98 adjacent each groove 94. Each capture region 98 is configured to direct lubricant 26 contacting the first end ring 74 into the respective groove 94. Although it will be understood that a plurality of capture regions 98 corresponding to a plurality of grooves 94 can be provided around the cage 70, the construction of one such groove 94 and capture region 98 is illustrated in Figs. 3 and 4. As shown in Fig. 4, the capture region 98 defines a portion of the first end ring 74 that extends axially beyond the end face 50' of the first race 30' in a direction away from the rolling elements 38'. In this manner, oil 26 moving radially outwardly between the end face 50' and the housing 22 (refer to Figs. 1 and 2) will impact a portion or surface 102 of each capture region 98 that is generally radially inward-facing. The portion or surface 102 includes a pair of surface portions 106 that flank the groove 94 on opposing circumferential sides. The surface portions 106 are converging surface portions that converge from opposite sides of the groove 94 toward and into the groove 94. In other words, the surface portions 106 each angle radially outward toward the groove 94 so that the capture region 98 is substantially concave. Although the capture region 98, and more particularly the specific geometry of the surface portions 106, can have various shapes, including arcuate, radiused, or inclined surfaces, the capture region 98 is generally concave to direct oil 26 into the groove 94. The shape of the surface portions 106 of the illustrated construction is best shown in Fig. 5 as generally V- shaped. Thus, the capture region 98 is configured to collect oil impacting and collecting on the portion or surface 102 that faces radially inwardly, and to direct oil flow as a funnel toward the groove 94 so that oil is urged toward the groove 94 from both adjacent circumferential sides of the groove 94. Boundaries between the capture region 98 and adjacent other capture regions 98 are formed at ridges 108 or generally convex surfaces that extend further radially inward compared to the adjacent capture regions 98 that they separate. A lip 110 formed at the axial end region of the capture region 98 helps to prevent oil 26 from escaping the portion or surface 102 in the axial direction, thereby containing more oil 26 in the capture region 98.
[0021] At least one of the first and second end rings 74, 78 includes a plurality of optional projections 114 extending radially relative to a central axis of the cage 70 for engaging a groove 118 formed in a bearing raceway 34'. As illustrated in Figs. 3 and 4, the projections 114 are on the first end ring 74 and extend radially inwardly into groove 118 formed in the raceway 34' of the first race 30'. The projections 114 extend radially beyond an interface defined by the raceway 34' and the outer rolling surface of the rolling elements 38', and are positioned axially beyond a distal axial end surface of the rolling elements 38'. The engagement of the projections 114 in the groove 118 hold the cage 70 and rolling elements 38' to the race 30' during handling of the bearing assembly 10', and enables the race 30' to be formed without the shoulder 46 required on the race 30 of the bearing assembly 10. The flange 80 at the second end ring 78 serves as a back-up to the projections 114 by axially overlapping the second race 54' to assure that the cage 70 cannot move toward the smaller diameter end of the rollers 38 'of the bearing (to the right in Fig. 4), even if the projections 114 become worn or damaged. The flange 80 is dimensioned to allow good clearance for the rolling elements 38' to be axially inserted in each pocket.
[0022] In other embodiments, the projections 114' (shown in phantom in Fig. 3) can extend radially outwardly from the first end ring 74 into a groove formed in the raceway 58' of the second race 54' (not shown). In yet other embodiments, the projections can be on the second end ring 78 and extend radially inwardly or outwardly into a groove formed in a respective raceway 34', 58' of the first or second races 30', 54'.
[0023] In operation of the illustrated cage 70, the cage 70 is axially located by contact with ends of the rolling elements 38'. With reference to Fig. 5, the cage 70 is held concentric to the bearing axis by the cage 70 contacting the rolling elements 38' at their outer peripheries above the pitch circle P. The pitch circle P, as is known to those skilled in the art, is the term defining a circle intersecting the centerlines of the rolling elements 38'. Wing surfaces 122 of the bridge 82 contact the rolling elements 38'. Although not illustrated, the bridge 82 can widen (left-to-right in Fig. 5) below the pitch circle P to extend the available room for the oil groove 94. It is to be understood that the application of this invention is not limited to cages that are centered by cage-to-roller contact above the pitch circle P. It is also possible to employ this invention when the cage is guided by cage-to-roller contact occurring below the pitch circle P, or with cages guided through contact with the inner or outer races.
[0024] Various features and advantages of the invention are set forth in the following claims.
