Definitions
- the invention relates to a metal cage for roller bearings, comprising two cage side parts, between which the rollers are accommodated.
- Such metal cages are used in particular for large-sized bearings.
- Exemplary here are large double-row tapered roller bearings for wind turbines (rotor bearings) with outside diameters greater than 1,500 mm to call.
- such metal cages are suitable for a wide variety of rolling bearing types with rollers as rolling elements, especially for larger radial and axial roller bearings, radial and axial spherical roller bearings, radial and axial tapered roller bearings and special types, such as combined multi-row roller bearings or tapered roller bearings.
- the metal cage serves to receive and guide the rollers.
- Such a metal cage is known for example from DE 26 08 308 A1.
- pin cage which is a solid cage whose bolts pass through axially drilled rollers in their bore.
- all rollers are provided with a bore through which a respective bolt, which connects the two cage side parts, is guided as a rotation axis.
- the manufacturing costs of such a pin cage are considerable, since the bolts must be hardened, ground and surface-treated, also the rollers are to pierce.
- the invention is therefore based on the problem of specifying a metal cage for roller bearings, which has a simpler structure.
- a plurality of the ball side parts firmly interconnecting holding elements are provided which are arranged substantially parallel to the axis of rotation of the two holding elements received, not rotatably mounted on the cage side parts and spaced from the holding elements rollers.
- the two cage side parts are connected by a plurality of holding elements extending between the two side parts. These retaining elements are used exclusively for the connection of the cage side parts, but they are not used for the storage of roles. These are located between the holding elements and are spaced therefrom. For their fixation separate spacers are used, which will be discussed below.
- the metal cage and the loosely mounted rollers form the roller ring arranged between two races.
- the holding elements have no axial function, since the rolls are inserted only in the area between two holding elements, the production of a metal cage according to the invention is substantially simpler, resulting in the end also in the construction of a roll bearing containing such a cage.
- the retaining elements may be designed as separate components, for example in the form of cylindrical retaining bolts or square retaining webs which are connected to the cage sides. This can be done by inserting into corresponding recesses on the cage side parts, screwing, welding or the like. In any case, the holding elements are located in an area laterally to the rollers.
- the holding elements can also be cross-sectionally round or polygonal here. As described, the retaining elements are spaced from the rollers, that is, they do not touch them. The rollers run on two opposite running surfaces of two opposing rings, against which they are mounted.
- spacers are expediently provided, which can preferably be releasably fixed to the holding elements.
- portions for releasably securing between two rollers to be positioned, these spaced spacers are provided on the holding elements.
- These spacers may be designed as small plastic or metal elements and are releasably attached to the corresponding sections on the holding elements. They grip between two adjacent rollers, the rollers are guided between two spacers, so that they can not touch each other as well as the holding elements.
- the sections on the holding elements themselves can be designed as cross-sectional constrictions or as push-through receptacles.
- a corresponding spacer which is designed as a latching clip, plugged so that it engages with its corresponding holding or guiding portion corresponding between two rollers.
- a through-recess for example, on a rectangular or flat running holding element, through which Extrasteckaus supraung the spacer is inserted, and in which he ared is ted.
- a retaining element is provided between each two rollers to be positioned.
- a variant of the invention provides that in each case one, two or more holding elements are arranged in the assembly position between two rollers, which serve to support a spacer to be guided between them and mounted thereon. While in the embodiment described above, for example, a necking on the constriction teclip snapped or inserted into the fürsteckausEnglishung a retaining clip and is engaged in the invention design with two arranged between the rollers holding elements of the spacers on this, preferably at the cage side parts in each case the two positioned between two rollers holding elements an opening for receiving a fixation of a spacer to be used serving fixing is provided.
- the holding elements serve only the support, while the spacer is held by a separate, preferably bolt-like fixing then in its position between two rollers and secured against tilting.
- axle bolts for pierced rollers further holding elements may be provided.
- These further, few retaining elements should expediently be distributed almost uniformly or symmetrically around the circumference of the cage.
- This embodiment of the invention is particularly suitable for the design of the metal cage with two separate cage side parts and separate holding elements. These few, forming a rotation axis holding elements serve primarily the stable accurate cage guide and to accommodate the cage weight, that is, the weight of the cage is supported on the axle bolts and rollers on one of the bearing rings.
- the invention further relates to a roller bearing, comprising two rings and at least one roller containing metal cage of the type described.
- FIG. 1 is a partial view of a metal cage according to the invention a first embodiment with dashed lines indicated rollers and spacers,
- Fig. 2 is a sectional view through an inventive roller bearing comprising the metal cage of Fig. 1, and
- Fig. 3 is an illustration of a metal cage of a second embodiment with dashed shown spacers and rollers.
- Fig. 1 shows a metal cage 1 according to the invention without rollers in the form of a partial view. It consists of two cage side parts 2, 3, wherein the metal cage 1 is used here, for example, to build a thrust roller bearing.
- the radius of the inner cage side member 3 which is designed as a ring, slightly smaller than the radius of the outer annular cage side part 2.
- the two cage side parts 2, 3 are holding elements 4, here in the form of cylindrical retaining pin 5, forming a stable metal cage firmly connected.
- the holding elements 4 are here so separate components that are fixed in a corresponding position on the cage side parts 2, 3.
- the cage side parts 2, 3 may have corresponding threaded or through holes into which the ends of the retaining bolts 5 are inserted, after which the retaining bolts 5 can also be welded, for example. It would also be conceivable to fasten these via a screw connection.
- the retaining bolts 5 are equidistant from each other around the circumference. They are used exclusively for fixing the two cage side parts 2, 3 to each other, they do not have a rotary axis forming function.
- the individual rollers 6 are, as shown in FIG. 2, respectively arranged between two holding elements. The rollers 6 themselves do not touch the retaining elements 4. to Guide the rollers 6 and determining the role position 4 spacers 7 are arranged on the support members.
- These may be designed, for example, as longitudinally slotted retaining clips which are fastened to the retaining elements 4 at corresponding fixing sections 8.
- these sections 8 are formed using the retaining bolts 5 as end diameter constrictions onto which a spacer 7 can be snapped, which has a corresponding retaining aperture or the like.
- an indentation 8 is provided at the ends of the retaining elements 4, so that in each case two spacers 7 can be fastened to each retaining element 4.
- the spacers 7 engage only peripherally on the rollers 6. These are therefore easily overlapped only at the edges, the other role is available for lubrication.
- the rollers 6 themselves are stored quasi loose, they are not in any bearing connection to the metal cage 1 itself. They are based only on the lower ring 9 and the upper ring 10 of the roller bearing 11 shown in FIG.
- FIG. 1 furthermore shows, a few rollers 6 can be mounted directly on the cage side parts 2, 3 for stability reasons.
- the two rollers 6 shown here are pierced in the center, through which engages a bearing pin 12, which is fixed at the end to the cage side parts 2, 3 and forms the axis of rotation for these rollers.
- the weight of the cage is supported via these few bearing bolts or axle bolts and a more accurate guidance of the cage is achieved.
- FIG. 3 shows a further embodiment of a metal cage 1 ', only one side view of the outer cage side part 2 being shown here.
- two bores 13 are provided, which serve for receiving in each case one end of a retaining element 4, preferably a retaining bolt 5.
- this embodiment of the invention are thus in the area between two rollers shown here in dashed lines 6, offset from the plane of rotation of the rollers 6 upwards, two retaining bolts 5, unlike the embodiment according to Hg.
- a further bore 14 is provided on the cage side part 2 on the opposite side, which is penetrated by a fixing element, preferably also a bolt, and passes through a corresponding break in the holding element T.
- a fixing element preferably also a bolt
- the holding element T is fixed in its position, in which it, supported on the holding elements, on the one hand slightly overlaps the rollers 6 in its edge region, on the other hand spaced the rollers in the area between them over its elongated portion.
- the spacer which in principle is designed as a sliding element in all embodiments, and can be made of plastic or metal (eg brass), thus fixes the rollers in their position and prevents contact between the rollers and the retaining elements.
- the metal cage according to the invention is still sufficiently stable, although the rollers are no longer directly mounted on it. Any welding work for connecting the holding elements 4 to the cage side parts 2, 3 can be carried out away from the bearing, that is to say the cage can be virtually prefabricated after the rolls are mounted "loosely.”
- the high circumferential utilization, ie the high number of rolling elements, remains Again, after the rollers can be placed very close to each other, only separated over the relatively narrow webs of the spacers., By the used, the rollers overlapping and leading Spacer made of plastic or metal also results in a low bearing frictional torque, also as a result of the fact that the spacers touch the rollers only in the edge region.
- the rolling elements themselves apart from the few optionally provided directly over the axle mounted rollers zen, are made of inexpensive bearing steel, it is no longer necessary to produce them from case steel and pierce, so that the total cost of manufacturing the metal cage as well as the Wälz stressessatzes can be reduced.
- Another conceivable embodiment provides for the production of a one-piece metal cage in the form of a casting, that is, the cage side parts 2, 3 and the retaining element 4 are produced in the form of a one-piece component using a corresponding mold.
- the casting is only to be reworked.
- the holding elements can also be designed here in the manner of a round bolt or as a polygonal web, so that they allow snapping or insertion of a suitable distance element.
