Definitions

  • the invention relates to a lubricant supply component for supplying a lubricant to a rolling bearing adjacent in the assembly position.
  • Rolling bearings are used in a wide variety of applications.
  • the automotive sector as well as industrial or machine tools can only be mentioned by way of example.
  • a rolling bearing is usually to lubricate, with a heavily loaded roller bearings, such as fast rotating spindle bearings, a permanent axial lubricant supply is required.
  • a Schmierstoffzu GmbHbauteil axially adjacent, that is to be arranged adjacent to the bearing to be supplied rolling bearing.
  • the annular lubricant supply member has a plurality of circumferentially distributed lubricant passages respectively through two bores, namely a radial bore opening at the radially outer side and an oblique bore opening at an axial end surface and leading into the radial bore , is formed. This makes it possible to supply the lubricant from radially outside the lubricant supply component and to bring it axially into the region between the bearing rings of the rolling bearing, preferably between the inner ring and a cage guiding the rolling bodies.
  • the invention is thus based on the object of specifying an improved lubricant supply component on the other hand.
  • a Schmierstoffzu Genevateil is provided according to the invention, which is characterized by an outer ring or inner ring and a radially arranged thereto, coupled to the outer ring or the inner ring feed element, wherein the outer or the inner ring one or more radial bores and the feed a or a plurality of communicating with the or the radial bores feed channels which open at an axial side surface of the feed element.
  • the lubricant supply component according to the invention is designed in two parts. It consists of an outer ring or an inner ring, which is preferably a standard component, for example a rolling bearing component such as an outer ring or an inner ring of such a bearing is.
  • This outer ring or inner ring is relatively narrow in wall thickness.
  • a number of radial bores are provided on it, which allow a radial supply of lubricant. These radial bores are relatively short due to the small thickness of the outer or inner ring, so that they can be formed on the ring side without problems.
  • a separate feed element Arranged on the outer or inner ring is a separate feed element, which has a plurality of feed channels, which open at an axial side surface of the feed element.
  • This feed element serves to continue the lubricant supplied via the radial bores of the outer or inner ring and to conduct it to the adjacent rolling bearing.
  • the feed element is more complex in geometry. This is readily possible when the feed element can be designed, for example, as a plastic component, since the actual stability of the lubricant supply component is ensured by the metal outer or inner ring.
  • the feed element has no mechanical support function, but merely serves to forward the lubricant.
  • the lubricant supply component Due to the division according to the invention of the lubricant supply component on the one hand the use of a standard component part of the outer or inner ring is possible, which is to be provided only with simple, short radial bores.
  • a geometry component can be integrated which, since it is preferably made of plastic, can be produced in a simple manner with a high geometric degree of freedom and consequently designed with regard to the specific application.
  • the lubricant supply component With the lubricant supply component, a low-noise, efficient axial lubrication of the adjacent rolling bearing is possible, while at the same time offering a high degree of adaptability to the given situation.
  • the feed element is formed in layers with simultaneous formation of the feed channel (s) in an additive process of at least one polymer material or at least one material based on a talls or a metal alloy is made.
  • the feed element is built up in layers, for which a corresponding program-controlled device is used.
  • the feed element is preferably produced in a powder bed process from a corresponding material powder, it being possible for the material to be either a polymer, that is to say that the feed element is a plastic component, or a material based on a metal or a metal alloy, that is, the feed element is then a metal component.
  • Such additive methods are known, for example, in the form of 3D printing, laser sintering, polyjet or stereolithography, with the correspondingly optimal method being selected depending on the material used. Since these methods are program-controlled, consequently, by appropriate configuration of the program, any geometry of the feed element can ultimately be created, both with regard to its exterior and with regard to its interior, ie the guidance and geometry of the feed channels. These can extend in quasi arbitrary form through the feed element, and be guided in particular bent, which is in view of the lowest possible flow resistance and thus a very good lubricant supply advantage.
  • the one or more feed channels may have a variety of geometry, particularly if a generative manufacturing process is used, regardless of whether the feed element is made of plastic or metal.
  • the one or more feed channels can be made oblique, angled or, preferably, curved.
  • an axially projecting annular collar is formed, in which open the one or more feed channels.
  • This axially projecting annular collar engages in the mounting position in the rolling bearing, ie between the outer and inner ring of the rolling bearing, so that the lubricant is discharged from the feeding element inside the rolling bearing itself, ie immediately adjacent to the actual Wälzetter Scheme to be supplied. This is particularly useful for lubricant supply because the lubricant is delivered where it is needed immediately.
  • a collecting space is provided, into which the one or more radial bores and the one or more feed channels open.
  • an annular collecting space is formed at the interface between outer or inner ring and the feed element, ie in the region where the radial bores or feed channels open, in which lubricant which is supplied via the radial bores collects.
  • This collection space thus forms a lubricant reservoir, which is filled as needed via the radial bore. For the actual supply of lubricant via the supply channels, sufficient lubricant is always available in the collecting chamber, so that the rolling bearing can always be supplied, if required for operational reasons.
  • the collecting chamber may be a collecting groove formed on the outer ring or on the inner ring and / or on the feeding element.
  • an annular collecting groove is formed on the inner wall of the outer ring, in which open the radial bores. It is conceivable that now the feed element connects directly to the inner wall, wherein the Feed channels communicate with this inside wall collecting groove.
  • this collection groove can of course also be provided on the supply element radially outboard, when the supply element is integrated in an outer ring and the like.
  • the collecting space is formed between the outer ring or the inner ring and the Zugarbauteil.
  • the feed component can be produced with a wide variety of external geometries.
  • the outer ring may be provided on its inner side with a correspondingly concave curved geometry, which is often the case anyway when using a standardized rolling bearing ring component.
  • the feed element is preferably held without tools on the outer or on the inner ring, that is the simplest way, by being pressed mechanically into the outer ring or pushed onto the inner ring.
  • it is retained in a positive and / or non-positive manner, ie it is fixed by means of corresponding holding geometries in conjunction with a slight interference fit or the like.
  • at least one retaining element is provided in the form of a cover disc fastened to the outer or inner ring or a retaining ring or the like arranged on the outer ring, on the inner ring or on the feed element.
  • an axial securing can be realized, wherein the cover plate, for example, positively and / or non-positively snapped into a radial groove of the outer or inner ring or is pressed into the outer or inner circumference of the respective ring.
  • a retaining ring for example, at least a sealing ring may be provided, via which the interface between the outer or inner ring and the feed element is sealed. This is accommodated, for example, on the feed element in a corresponding groove, it rests against the respective ring with sufficient rigidity, so that there is also sufficient force or positive fixation over this.
  • latching or snap elements are provided on the feed, which engage or snap into provided on the outer ring or on the inner ring latching or snap sections.
  • Such latching or snap elements can easily be formed on the feed element, which is preferably made of plastic, be it that it is produced generatively, ie in an additive layer process, or that it is produced in a conventional plastics processing method such as an injection molding process.
  • the detent or snap portions provided on the ring can be easily formed by simple mechanical machining of the metal ring, unless a suitable geometry is given from the house. As part of the assembly, it is only necessary to put the feeding element into the ring until the snap-in or snap-in elements snap into the corresponding snap-in or snap-on sections or snag there.
  • roller bearings are installed in combination to rotatably mount a component. If, for example, two such roller bearings are provided adjacent to one another, then both are to be lubricated correspondingly axially.
  • a particularly expedient development now provides that the one or more feed channels branch off to both axial surfaces of the feed element. If appropriate, they can open on both sides in an axially projecting annular collar.
  • This advantageous embodiment of the invention makes it possible to guide the lubricant to both sides of the lubricant supply component, so that lubricant can be supplied simultaneously by means of a lubricant supply component to two rolling bearings arranged on both sides of the supply component. It is therefore only a lubricant supply component required for the lubrication of two bearings, which makes it possible to perform the entire rolling bearing assembly in the axial direction relatively narrow.
  • branching feed channels are readily possible when producing the feed component in an additive method, such as the method variants mentioned above, since, as stated, there is an extremely high variability and design freedom with regard to the channel geometry and guidance. As far as possible, a symmetrical structure is preferred if possible and expedient in terms of geometry, which, however, can not be realized in every case.

  • a corresponding interface is provided between these two feed parts, which makes it possible to mount the second feed part in two defined positions or orientations firmly on the first feed component.
