Definitions
- the invention relates to a cage for a rolling bearing as such comprises a ring body which defines a plurality of circumferentially following and separated by web sections window openings which serve to receive Wälzkörpem. Furthermore, the invention also relates to a method for producing such a cage.
- Cages of the aforementioned type are used in particular to ensure a required distance in the circumferential direction between the rolling elements of a rolling bearing.
- the corresponding cages also serve to secure a required alignment, as well as, if necessary, the lateral guidance of the rolling bodies.
- cages made of metal materials and plastic cages are widely used. From DE 33 27 623 A1, for example, a window cage is known, which comprises a relatively thick-walled executed annular body in which a plurality of receiving windows are formed. Cylindrical rollers are accommodated in the respective recording windows. The outer circumferential surface of the respective cylindrical rollers facing inner walls of the receiving windows are profiled to achieve a certain guiding and holding action.
- a window cage which comprises a relatively thick-walled and provided with receiving windows ring body.
- the ring body is divided into at least two half shells.
- the inner walls of the receiving windows are designed in such a way that the correspondingly guided rolling bodies are submerged underneath a rolling body pitch circle. This makes it possible to create a contact surface on the rolling elements by which a centrifugal force-induced widening of the half-shells can be counteracted.
- a window cage for a cylindrical roller bearing which comprises a ring body which is made of a relatively thin sheet material.
- the ring body is profiled and provided in the region of its peripheral edges with a curl, resulting in the region of those peripheral edges a relatively massive structure comprising two material layers.
- a segment cage which comprises a plurality of plastic segments adjoining one another via tilt contact surfaces. These plastic segments are provided in a region adjacent to the side edges with grooves and inserted through these grooves in a pair of rings.
- a linkage cage which comprises several window members. These window members are designed such that they are articulated to each other in the manner of a link chain.
- a cage element for a cross roller bearing is known which also comprises a plurality of window members which are combined via a locking ring pair to form a window cage.
- the invention has for its object to show solutions by which can be efficiently manufactured at a cost in terms of design freedom in terms of the cage diameter and the Wälz stresses- leadership, window cages for rolling bearings.
- first support ring - a second support ring, and a plurality of cage segments which are combined as such via the two support rings to form a ring body
- cage segments are designed as Blechumformmaschine, and are each provided with receiving structures, for receiving a medicinalsab- section of the respective support ring.
- the cage segments of the invention can be manufactured in a technically advantageous manner from a sheet metal strip by stamping / bending.
- the individual cage segments are designed in such a way that the receiving structures formed on the peripheral edge region thereof are designed as channel sections.
- These channel sections can be designed so that they are matched in their cross-section to the cross-section of the respective support ring, that they can be clamped with a relatively resilient clamping fit on the respective support ring.
- the receiving structures can be designed so that the cage segments are placed essentially from the outside on the two support rings and in this case engage over the respective outer peripheral portion of the support ring from the outside. Alternatively, or in combination with this measure, it is possible to form the receiving structures so that they engage under the respective peripheral portion of the support ring from the inside.
- the respective cage segments are materially connected to the support rings. This material connection is preferably accomplished via welds. These welds can in particular be designed as laser welding points. About the welds, the segments can be welded together and the segments with the support rings. As an alternative to the realization of the material connection by welding joints, or in combination with this measure, it is also possible to solder the cage segments with the support rings.
- a particularly high-strength and rigid design of the window cage can be achieved by also the respective adjacent cage segments connected to each other, in particular welded by welding joints. It is possible to form the cage segments in the region of the respective relevant zones for the formation of the welds so that in this way particularly favorable structures, for example overlapping or plug-in sections for the realization of the weld joint are given.
- each cage segment is formed so that it forms a provided for receiving a rolling element, in particular a cylindrical roller guide window.
- This guide window can be designed such that it comprises a peripheral edge pair extending in the circumferential direction of the window cage and an axial flank pair extending transversely to the direction of rotation. Both the peripheral flank pair and the axial flank pair are preferably designed such that this forms guide walls, by means of which an advantageous circumferential and lateral guidance of the respective rolling element is made possible.
- the two circumferential flanks of the respective cage segment, each extending in the circumferential direction of the window cage can be designed such that they form a channel structure which snugs closely against the corresponding outer surface of the respective support ring. This channel structure makes it possible to achieve a favorable introduction of force between the respective cage segment and the support ring and, moreover, to stiffen the cage segment in each case relatively effectively.
- the axial flanks of the respective cage segment which extend transversely to the direction of rotation of the window cage can be designed so that they each form a guide web which, as such, comprises land zones which extend at different radial heights.
- these axial flanks so that a window cage is formed, in which the corresponding rolling elements are secured in the cage easily.
- These guide walls can be formed by the cut walls of the respective cage segment as well as by forming sections, in particular unfolded guide flanks.
- the cage segments can be formed as single-part or multi-part frame structures, which as such define a receiving opening serving to receive and guide the rolling bodies.
- the cage segments can also be formed by initially separate crossbar elements.
- each transverse web has edge sections extending substantially at the level of the supporting ring, and these channels are incorporated into the receiving structures as such. between these edge portions is preferably located below the pitch diameter of the WälzSystembahn lowered bridge portion is connected via ascending connecting leg to the edge portions.
- the length, measured in the direction of a circumferential axis, of this radially inwardly countersunk bridge section is preferably at least 30% of the axial length of the rolling element to be guided.
- the cage segments can be designed so that their raceway height, or track distance relative to the pitch circle of the rolling bearing in a range of about 20% of the rolling element diameter relative to the pitch circle diameter is variably fixed.
- the support rings themselves are preferably designed so that their diameter corresponds at least to the pitch circle diameter of the rolling body track.
- the support rings are preferably made of a high-strength steel material, in particular bent and welded frontally.
- this connection point of the flat or wire material used to form the support rings is placed so that the support rings are each closed via a cage segment, so that this joint is bridged by a peripheral edge of the respective cage segment.
- the connection points of the support rings are placed so that these diametrically opposite circumferential areas of the window cage are located.
- the invention is also directed to a rolling bearing per se, which is equipped with a window cage of the aforementioned type.
- the rolling elements of this rolling bearing are preferably designed as cylindrical rollers.
- the support rings can be designed as wire rings with a substantially circular Torusquerêt.
- the support rings may also have a substantially rectangular, or groove-like Torusquerites. It is also possible to attach cover rings to the window cage, in particular vulcanized from an elastomer material, by means of which a lateral bearing seal is achieved.

- the cage segments S are locally welded together with the two support rings 1, 2 and with each other in the region of the abutting end faces.
- the respective cage segment S forms receiving structures AR1, AR2 and AL1, AL2.
- These receiving structures AR1, AR2, AL1, AL2 are executed in the embodiment shown here as Pratzen- or gutter sections, which engage over the respective peripheral portion of the support ring 1, 2 (see Figure 3) from the outside. It is also possible to configure these receiving structures AR1, AR2, AL1, AL2 such that the channel sections provided by them are exposed radially outwards and thus engage under the respective peripheral section of the supporting ring from the inside.
- the cage segments S are each formed so that they form a for receiving a rolling element W, (here cylindrical rollers) provided guide window F.
- This guide window F comprises a circumferentially extending pair of flanks LL, LR and an axial flank pair LQ1, LQ2 extending transversely to the circumferential direction of the cage.

- the transverse flanks LQ1, LQ2 can be welded together via the welds SZ shown here.
- the welds can be designed as local, point-like welds or as longitudinal seam welds. It is possible, in addition to the welds shown here, or in combination herewith additionally to solder the cage segments with the support rings 1.
- the cage thus created can be aligned by a calibration tool.
- the cage may be subjected to a heat treatment and, for example, an electrochemical surface treatment.
- On the cage further bearing elements, in particular lubricant-releasing plastic elements can be attached.
- FIG. 5 shows, in the form of a perspective detailed representation, a cylindrical roller bearing which is provided with a window cage according to the invention.
- This cylindrical roller bearing comprises an inner ring 11 and an outer ring 12 between the inner ring 11 and the outer ring 12 are incorporated by incorporating the window cage according to the invention rolling elements W, which are designed here as cylindrical rollers.

- the cage segments S are in this embodiment, as described in connection with Figure 4, welded to the support rings 1, 2.
- the corresponding cage segments S can be snapped onto a matched to the pitch circle diameter of the bearing bearing ring and each materially connected to this support ring.
- the cage segments classic cage profiles, especially M-profiles and W-profiles can be realized.
- the cage segments can form part of a modular system through which window cages can be manufactured with a wide variety of pitch diameters.
- the segments and the rollers located therein can be manufactured as a basic unit by which a equipped with rolling elements cage can be made especially for small series or special camp. Segment and roller represent a 1: 1 relationship. This assembly can be installed in different sized bearings. Only the number of segments is matched to the corresponding bearing diameter:
- the inventively constructed cage can be equipped with other bearing components.
- the cage constructed according to the invention can also be injected as an insert-molding component into a plastic body. It is also possible to use other plastic structures, e.g. To impart Wälz redesignst- basket to the cage according to the invention or e.g. via catch structures.
- the cage segments can be matched in terms of their geometry and overall design to each leading to rolling elements, in particular cylindrical rollers, i.
- the width and the arc length of the respective segment are adjusted so that the segment strength is sufficient for the corresponding roll size.
- the cage segment can be produced in large numbers, in particular in the subsequent step process from a sheet metal strip.
- the contour of the cage segment can in this case in particular be designed so that in this way an M-profile is achieved. This contour makes it possible to guide the cylindrical rollers both inwards, as well as to secure against falling outwards.
- the support rings can be made of a wire or sheet metal material.
- corresponding wire sections are cut to length and bent to a toms of the required diameter.
- This Toms is preferably welded in the region of the end faces of the wire material.
- the weld is preferably located at a location bridged by a cage segment attached to the trangring.
- the segments are assembled by picking up the individual segments with the receiving structures attached to their two longitudinal sides running in the circumferential direction, in particular tabs on the wire rings made, for example, from round wire. After fitting the wire rings with all segments, the segments are welded together and preferably also with the support rings.
- the bent and preferably butt-welded carrier rings are calibrated to the required extent of the bearing.
- care is taken to ensure that the sum of the segment arc lengths corresponds to the length of the circumference of the carrier ring. This ensures that after assembly, a possibly small gap between the end faces of the adjacent segments remains. It is possible to make the segments so that they overlap in the region of their adjacent ends. This makes it possible to compensate for the degree of overlap an excess of the circumferential length of the respective cage segment on the pitch. Furthermore, it is possible to furthersectionsteifen by this overlap and the transverse webs.
- FIG. 6a it is possible to design the receiving structure AR1 such that it is located at the lateral outlet end of the transverse web LQ 1 and thus ties it relatively stiffly to the carrier ring 1.
- the receiving structure AR1 is designed so that it can be snapped onto the support ring 1 with a relatively high holding force.
- the support ring 1 is made of a wire material which is bent into a ring. The corresponding end sections of wire material are welded.
- FIG. 6b shows a variant of the receiving structure AR1 in which it engages under a section of the support ring 1 from the inside.
- the support ring 1 is made of a strip material and provided with a flange.
- the receiving structure AR1 engages under an inwardly formed circumferential ridge formed by the flange.
- the support ring 1 is provided with a clamping V by which the cage segment S is secured to the support ring 1 in a form-fitting manner.
- the inventive concept is also suitable for the realization of window cages for rolling elements in the form of spherical rollers and optionally also for guiding rolling elements in the form of balls.
- the solution according to the invention also includes WälzMechhimfige, in which individual cross bar elements are set, leaving a determined by the rolling elements to be guided U meks- distance to the carrier rings.
