Opfindelsen angår en indretning til "kompensering af det radiale spillerum af et rulningsleje i en leje"boring ved hjælp af en foran rulningslejets endeflade lejret skive, som ved sin omkreds er udformet med et aksialt rettet fremspring, 5 som griber ind det radiale spillerum, og som er afpasset efter dette til opnåelse af et bestemt radialt tryk. En sådan indretning er kendt fra DE-patentskrift 851 865·BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a device for "compensating the radial clearance of a rolling bearing in a bearing" bore by means of a disc mounted in front of the end surface of the rolling bearing, which is circumferentially formed with an axially directed projection 5 which engages the radial clearance and which is adapted to this to achieve a certain radial pressure. Such a device is known from DE patent specification 851 865 ·
Ved den kendte indretning indføres et ringformet, i radial retning deformerbart mellemorgan i mellemrummet mellem 10 de til forbindelse bestemte dele af en friktionsforbindelse, hvorhos mellemorganets radiale dimension er således afpasset efter det radiale spillerum, at der ved forbindelsen opstår en plastisk deformering af mellemorganet. Ifølge en særlig udførelsesform består indretningen til kompensering af det 15 radiale spillerum i firktionsforbindelsen af en hovedsagelig cirkulær plade, som ved sin omkreds er forsynet med indskæringer til dannelse af tunger, som er ombukket i en ret vinkel i forhold til pladens plane midterdel. Disse i en kreds anbragte tunger er i sig selv krummede, hvorhos deres konkave 20 sider er rettet udad. Ved montagen presses de i sig selv krummede tunger ind i det radiale spillerum, hvorhos tungernes udbøjning, vægtykkelse og bredde samt indbyrdes afstand er således valgt med henblik på størrelsen af mellemrummet, at man opnår det ønskede radiale tryk på lejet.In the known device, an annular, radially deformable intermediate member is inserted in the space between the parts of a frictional connection to be determined, the radial dimension of the intermediate member being so adapted to the radial clearance that a plastic deformation of the intermediate member is formed at the connection. According to a particular embodiment, the device for compensating the radial clearance in the four-joint connection consists of a substantially circular plate, which at its perimeter is provided with incisions for forming tongues which are bent at a right angle to the plane center portion of the plate. These tongues placed in a circle are themselves curved, with their concave 20 sides directed outward. In mounting, the curved tongues themselves are pressed into the radial clearance, whereby the deflection, wall thickness and width of the tongues are so chosen for the size of the gap as to achieve the desired radial pressure on the bearing.
25 Den foreliggende opfindelse har til opgave at tilveje bringe en i forhold hertil med hensyn til fremstilling og montage væsentligt enklere indretning til kompensering af det radiale spillerum.The object of the present invention is to provide a substantially simpler device for making and assembling the radial clearance space.
Ifølge opfindelsen løses denne opgave ved en indretning 30 af den indledningsvis nævnte art ved, at der ved et rulningsleje er anbragt en skive, som er udformet med en aksialt rettet rand i form af en mod den ydre omkredsflade af rulningslejet rettet kile, som ved hjælp af den aksiale forspændingskraft fra et fjederelement er trykket ind i spillerummet mel-35 lem rulningslejet og lejeboringen til udligning af det fore-According to the invention, this object is solved by a device 30 of the type mentioned in the introduction, in that a roller bearing is provided with a disc which is formed with an axially directed rim in the form of a wedge directed against the outer circumferential surface of the rolling bed, of the axial biasing force of a spring element is pressed into the clearance between the rolling bed and the bearing bore to compensate for the

Den ifølge opfindelsen som skive med derpå udformet kileformet yderrand og tilhørende fjeder udformede indretning til kompensation af det radiale spillerum kan dels fremstil-5 les meget enkelt, navnlig som en i ét stykke udført sprøjte-godsdel, der ikke kræver yderligere efterbearbejdning, dels monteres ved simpel mellemlægning ved montering af rulnings-lejet.The disc according to the invention as a disc with a wedge-shaped outer edge and associated spring-shaped device for compensating the radial clearance can be manufactured very simply, in particular as a one-piece syringe piece which does not require further finishing, and can be mounted by simple insertion when mounting the roller bearing.
Det er kendt til forspænding af et rulningsleje og til 10 undgåelse af støjudvikling på grund af lejespillerummet mellem yderringen og inderringen i lejet at anbringe enfjeder, som i form af en skruefjeder med sin ene ende ligger an mod en skulder i lejeskjoldets lejeboring og med sin anden ende ligger an mod endefladen af rulningslejets yderring. Ved en 15 sådan forspænding af lejet kan lejespillerummet mellem inder-ring og yderring og den deraf ellers betingede støj sænkes betydeligt ved indbyrde aksial forskydning af lejets yderring og dets på akslen fastholdte inderring under indvirkning af skruefjederens aksiale tryk.It is known to bias a rolling bearing and to avoid noise development due to the bearing clearance between the outer ring and the inner ring of the bearing to place a spring which in the form of a coil spring with one end abuts a shoulder in the bearing bore of the bearing shield and with its other end abuts the end surface of the outer ring of the roller bearing. In such a biasing of the bearing, the bearing clearance between the inner ring and outer ring and the otherwise conditioned noise can be considerably lowered by mutual axial displacement of the outer ring of the bearing and its inner ring held by the axial pressure of the coil spring.
20 Til yderligere formindskelse af dette lejespillerum og tillige til undgåelse af et radialt spillerum mellem rullelejets ydre omkredsflade, dvs. lejets yderring, og lejeboringen i elejskjoldet er nu skiven med den derpå udformede aksi-ale rand i form af en mod yderringen rettet kile indlagt mel-25 lem den fra skulderen bortvendende ende af skruefjederen og rulningslejets yderring, så at kilen ved skruefjederens aksi-ale forspændingskraft trykkes ind i spillerummet mellem rulningslejet og lejeboringen til yderligere udligning af det foreliggende radiale spillerum. Skiven med den derpå udforme-30 de rand kan herved under indvirkning af den aksiale forspæn-dingskraft, som på kilens skråflade bevirker en aksial og en radial kraftkomposant, tilpasse sig efter det eventuelt variable radiale spillerum mellem rulningslejets yderring og lejeboringen.20 To further reduce this bearing clearance and also to avoid a radial clearance between the outer circumferential surface of the roller bearing, ie. the outer ring of the bearing, and the bearing bore in the ele shield is now the disc with the axial rim formed thereon in the form of a wedge facing the outer ring between the end of the screw spring facing away from the shoulder and the outer ring of the roller bearing so that the wedge at the axial axis of the screw spring biasing force is pressed into the clearance between the rolling bearing and the bearing bore to further equalize the radial clearance available. The disc with the then formed rim can hereby, under the action of the axial biasing force, which produces on the inclined surface of the wedge an axial and a radial force component, adapt to the possibly variable radial clearance between the outer ring of the roller bearing and the bearing bore.

- 3 - og udformningen ifølge opfindelsen af skiven med den kileformede rand opnås ikke blot, at de ved bearbejdningstolerancer givne pasningsspillerum ophæves, og at yderringen på grund af sin tilspændingsmulighed på den kileformede rand trykkes til 5 en efter inderringen afpasset placering af løbebanen, men også at lejet sidder pasningsspillerumsfrit under driften, hvis størrelsen af lejespillerummet ændres driftsmæssigt, fx. på grund af opvarmning ved forskellig udvidelseskoefficient af henholdsvis lejeboringen og lejet.- 3 - and the design according to the invention of the wedge-shaped rim disc not only achieves that the clearance clearance given by machining tolerances is obtained and that the outer ring, due to its tensioning ability on the wedge-shaped rim, is pressed to a position of the runway adapted to the inner ring, but also that the bearing sits passroom free of charge during operation if the size of the bearing space is changed operationally, e.g. due to heating at different coefficient of expansion of the bearing bore and the bearing respectively.
10 Ifølge en særlig udførelsesform for opfindelsen er ind retningen ejendommelig ved, at kilen har et usymmetrisk tværsnit med en første, radialt ydre, parallelt med lejeboringen forløbende kileflade og en anden, radialt indre, konisk og i forhold til den ydre omkredsflade af rulningslejet skråtstil-15 let kileflade. Derved opnås dels et godt styret anlæg af kileskiven i lejeboringen, dels en sikker virksomhed af kileskråfladen til undgåelse af et uønsket radialt spillerum.According to a particular embodiment of the invention, the device is characterized in that the wedge has an asymmetrical cross-section with a first radially outer, parallel to the bearing bore and a second radially inner, tapered and inclined relative to the outer circumferential surface of the rolling bearing. 15 light wedge surface. This results in a well-controlled installation of the wedge disc in the bearing bore and a secure operation of the wedge bevel surface to avoid an undesirable radial clearance.
Hvis skiven derimod udformes symmetrisk med ved omkredsen af hver af dens to endeflader udformede, i den ene og den 20 anden akseretning rettede rande i form af kiler, opnås ved monteringen samtidig på enkel måde en centrering af den aksi-alkraften bevirkende og til tilspænding af lejet bestemte trykfjeder, og det bliver unødvendigt at tage hensyn til en bestemt indskydningsside af kilen.On the contrary, if the disc is designed symmetrically with the edges of each of its two end faces, shaped in the one and the other axial directions in the form of wedges, at the same time a simple centering of the axial force acting and for tightening the axial force is obtained. bearing certain compression springs, and it becomes unnecessary to take into account a particular insertion side of the wedge.
25 En med hensyn til fremstilling og montering særlig for delagtig yderligere udformning af indretningen ifølge opfindelsen til kompensering af det radiale spillerum af et rulningsleje er ejendommeligt ved, at fjederelementet sammen med skiven og den derpå aksialt udformede rand i form af en mod 50 den ydre omkredsflade (yderring) rettet kile er udformet som en som et enkelt stykke håndterbar montagedel. I dette øjemed er skiven med den aksialt rettede rand og fjederelementet dannet af et enkelt stykke formstof, navnlig som en i ét stykke udført form-, sprøjte- eller støbedel.One with regard to manufacturing and mounting, in particular for partially further forming the device according to the invention for compensating the radial clearance of a rolling bearing, is characterized in that the spring element together with the disc and the axially formed rim in the form of an outer circumferential surface 50 (outer ring) directed wedge is designed as a single piece manageable mounting part. For this purpose, the disc with the axially directed rim and the spring element is formed of a single piece of plastic, in particular as a one-piece molding, spraying or molding part.

Hvis der som rulningsleje anvendes et kugleleje, er skiven i så fald således 5 udformet, at den ikke kan slæbe på kuglelejets roterende in-derring. Hvis akselenden ikke strækker sig aksialt ud over lejeskjoldet, kan skiven også på fordelagtig måde tillige væreeudformet som en lejekappe, der aftætter hele akseltappens lejring udad.dial clearance formed disc with one-piece edge thus formed and at the same time associated spring element also be designed as dust disk for the rolling bed. In this case, if a ball bearing is used as a ball bearing, the disk is designed 5 so that it cannot drag on the rotating inner ring of the ball bearing. If the shaft end does not extend axially beyond the bearing shield, the disc may also advantageously be designed as a bearing sheath which seals the entire shaft pin bearing outward.
10 For at skiven med sin kileformede rand, alt efter det radiale spillerum, som skal udlignes skal kunne tilpasse sig efter de forskellige radiale mål af de pågældende anlægspunkter af den skrå kileflade mod den ydre omkredsflade af rulningslejet, er en vis elastisk eftergivelighed af materialet 15 hensigtsmæssigt, navnlig ved en ubrudt rundtgående kileformet rand. Til en mere målrettet forandring eller fastlæggelse af skivens fjedringsevne og til optimal afpasning mellem skivens materiale og den aksialt tiltrykkende aksialkraft er skiven ifølge en yderligere udførelsesform for opfindelsen forsynet 20 med en aksialt rundtgående, ved slidseformede udsparinger afbrudt rand.10 In order for the disc with its wedge-shaped edge, according to the radial clearance to be equalized, to be able to adapt to the different radial dimensions of the respective abutment points of the inclined wedge surface towards the outer circumferential surface of the rolling bed, some elastic resilience of the material 15 appropriate, especially at a continuous circumferential wedge-shaped rim. For a more targeted change or determination of the spring capability of the disc and for optimal alignment between the material of the disc and the axially pressing axial force, the disc according to a further embodiment of the invention is provided with an axially circumferential, cut-off cut-off edge.

Derved trykkes samtidig også kuglelejets yderring ved anlægget mod kileringen til en efter den fastholdte inderring afpasset placering af løbebanen. Derved bliver en del af de produktionstolerancer, med hvilke kuglelejet selv er behæftet, virkningsløse.1, with a designated clearance between the outer circumferential surface of the outer ring 31 of the rolling bearing 3 and the inner circumferential surface of the bearing bore 41 in the bearing shield 4, the disc 2 5 is pressed by the coil spring 22 against the outer bearing 31 of the ball bearing 3 with an axially formed edge in a wedge 21 directed towards the outer ring 31 of the rolling bearing 3, which is pressed into the clearance space 5 by the axial biasing force 5 of the radial size a between the rolling bearing 3 and the bearing bore 41 to compensate for the radial clearance space a. the outer ring of the ball bearing at the abutment against the wedge ring to a positioning of the runway adapted to the inner ring. As a result, some of the production tolerances with which the ball bearing itself is attached become ineffective.

Hvis akselenden ikke strækker sig 20 aksialt ud over lejeskjoldet, kan skiven også på fordelagtig måde tillige være udformet som en lejekappe, der samtidig af-tætter hele lejeringen af akseltappen udad. Hensigtsmæssigt er den på skiven 2 udformede kileformede rand 21 forsynet med et usymmetrisk tværsnit med en første, radialt ydre, paral-25 lelt med lejeboringen 41 forløbende kileflade 211 og en anden, radialt indre, konisk og i forhold til den ydre omkredsflade af rulningslejet 3's yderring 31 skråt forløbende kileflade 212.Conveniently, washer 2 is configured as a dust disc for roller bearing 3 so that the inner hearing of the disc 2 is close to the outer diameter of the motor shaft 6 and is spaced away from the inner ring 32 so that drag on the rotating inner ring 32 is avoided. If the shaft end does not extend axially beyond the bearing shield, the disc may also advantageously also be formed as a bearing sheath which simultaneously seals the entire bearing of the shaft pin outwards. Conveniently, the wedge-shaped rim 21 formed on the disc 2 is provided with an asymmetrical cross-section with a first radially outer parallel to the bearing bore 41 extending wedge surface 211 and a second radially inner, conical and relative to the outer circumferential surface of the rolling bearing 3. outer ring 31 inclined wedge surface 212.
