Opfindelsen angår et glideleje af keramisk materiale til lejring af pumpeaksler, hvor en lejebøsning, der roterer med akselen, løber inden i en af det samme materiale bestående lejeskål, og lejeskålen er fastgjort 5 elastisk inden i et hus, og hvor der som lejemateriale navnlig anvendes siliciumkarbid.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a ceramic sliding bearing for pump shaft bearing wherein a bearing bush rotating with the shaft runs within a bearing material of the same material and the bearing bowl is resiliently secured within a housing, where bearing material is particularly used. silicon carbide.

Fra DE-patentskrift nr. 2.923.075 og DE-fremlæg-gelsesskrift nr. 1.528.640 kendes der oxidkeramiske aksellejringer, der er bestemt for anvendelse i centrifu-10 galpumper, og hvor lejeskålen er anbragt inden i en bøsning, som under indskydning af en O-ring er fastgjort elastisk i huset. Denne løsning har den ulempe, at der ikke er garanti for en tilstrækkelig drejesikring. Som følge af aflejringer mellem den stillestående og den ro-15 terende del kan der således ske en blokering, som resulterer i en ødelæggelse af det elastiske element.DE Patent Specification No. 2,923,075 and German Patent Specification No. 1,528,640 disclose oxide ceramic shaft bearings intended for use in centrifugal pumps and wherein the bearing bowl is housed within a sleeve which, during insertion of the an O-ring is elastically fastened in the housing. This solution has the disadvantage that there is no guarantee of adequate turning protection. Thus, due to deposits between the stagnant and the rotating member, a blockage can occur which results in a destruction of the elastic member.

Opfindelsen har til opgave - for sådanne keramiske lejeskåle at udvikle en støddæmpende oq udlignende lejring, som på pålidelig måde garanterer en sikker fik-20 sering af lejeskålen.It is the object of the invention - for such ceramic bearing bowls, to develop a shock absorbing and equalizing bearing which reliably guarantees a secure fixation of the bearing bowl.

Til opnåelse heraf er glidelejet ifølge opfindelsen ejendommeligt ved, at lejeskålen på sin ydre omkreds har en eller flere noter, der er anbragt i afstand i forhold til lejeskålendesiden og har et afrundet tvær-25 snit, at lejeskålen udvendig er overtrukket med et slangeformet gummielement, og at fremspring, der er anbragt på indersiden af gummielementet, er i lejesikrende indgreb i lejeskålens noter.To achieve this, the sliding bed according to the invention is characterized in that the bearing bowl has on its outer circumference one or more grooves spaced from the bearing bowl side and has a rounded cross-section, that the bearing bowl is externally coated with a hose-shaped rubber element, and that projections disposed on the inside of the rubber member are in anti-locking engagement with the groove bowl notes.

Med sådanne noter opnår man en lejesikring såvel 30 i radial som i aksial retning. På grund af de afrundede noter og deres anordning i afstand i forhold til leje-skålendesiden opnås der sikkerhed for, at der ved en overmåde stor belastning, der f.eks. kan forekomme som følge af akselnedbøjninger, stød eller skråstillinger, 35 overhovedet ikke kan ske nogen brydning af lejeskålen.With such notes, a bearing lock 30 is obtained in both radial and axial directions. Because of the rounded notes and their arrangement at a distance from the bearing bowl end side, it is assured that an excessively large load, e.g. may occur as a result of shaft deflections, bumps or slopes, no breakage of the bearing bowl at all.

En fordelagtig udførelsesform for glidelejet i-følge opfindelsen er ejendommelig ved, at der er anbragt et klæbestof mellem gummielementet og lejeskålen. Med denne udformning kan man opnå en yderligere lejesikring 5 af lejeskålen inden i det slangeformede gummielement. Dertil kommer, at der ved anvendelse af tætninger, som er anbragt foran eller efter lejet, opnås en yderligere tætningsanordning.An advantageous embodiment of the slide bed according to the invention is characterized in that an adhesive is arranged between the rubber element and the bearing bowl. With this design, an additional bearing lock 5 of the bearing bowl can be obtained within the tubular rubber element. In addition, by using seals placed in front of or after the bed, an additional sealing device is obtained.

En anden fordelagtig udførelsesform for glide-10 lejet ifølge opfindelsen er ejendommelig ved, at gummielementet er fastgjort med klæbestof i huset. Herved kan der på en enkel måde foretages en montage, som forudser, at lejeskålen ikke udsættes for en farliq belastning, idet der under montagen udelukkende indvirkes på det 15 elastiske gummie1ement.Another advantageous embodiment of the slide bearing according to the invention is characterized in that the rubber element is fixed with adhesive in the housing. In this way, a mounting can be made in a simple manner which ensures that the bearing bowl is not subjected to a dangerous load, since during the installation the effect is exclusively on the elastic rubber element.

Opfindelsen forklares nærmere i det følgende ved en udførelsesform under henvisning til tegningen, hvor fig. 1 viser et perspektivbillede af en lejeskål, og 20 fig. 2 et tværsnit af en monteret lejeforbindel se.The invention will be explained in more detail below in an embodiment with reference to the drawing, in which fig. 1 is a perspective view of a bearing bowl, and FIG. 2 is a cross-sectional view of a mounted bearing joint.

Pig. 1 viser i perspektivbillede en lejeskål 1, der består af siliciumkarbid, og som på sin yderflade har noter 2, 3 med et afrundet tværsnit. Man hindrer 25 herved på pålidelig måde en brydning af lejeskålen 1. Noterne 2, 3 er desuden anbragt i afstand i forhold til lejeskålendesiderne 4, hvorved en mulig brudrisiko formindskes yderligere. Noterne kan forløbe i radial og/eller i aksial retning.Pig. 1 is a perspective view of a bearing bowl 1 consisting of silicon carbide, which has on its outer surface notes 2, 3 with a rounded cross-section. In this way 25 is reliably prevented from breaking the bearing bowl 1. The notes 2, 3 are further spaced from the bearing bowl sides 4, thereby further reducing a possible breaking risk. The notes may extend radially and / or axially.

30 Fig. 2 viser en monteret lejeanordning. På en aksel 5 er der anbragt en med denne roterende lejebøsning 6, der løber inden i en af det samme materiale bestående lejeskål 1. Lejeskålen 1 er på sin yderside overtrukket med et slangeformet gummielement 7, 35 hvis på indersiden anbragte fremspring 8 er i dreje-FIG. 2 shows a mounted bearing device. A shaft 5 is provided with a rotating bearing sleeve 6 which runs within a bearing bowl 1 of the same material. -

3 sikrende låseindgreb i lejeskålen l's noter 2. Gummielementet 7 holdes her i sin position inden i et hus 9 ved hjælp af et klæbestof, f.eks. "Volcoferran" fra HAW, Borum. Klæbestoffet forbinder gummielementet 7 5 pålideligt med det metalliske hus 9 og er olie-, lud-og syrebestandigt, for at forbindelsen kan forblive pålidelig ved anvendelse i alle arter vand.3 the locking element 7 is held here in its position within a housing 9 by means of an adhesive, e.g. "Volcoferran" from HAW, Borum. The adhesive reliably connects the rubber element 75 to the metallic housing 9 and is oil, lye and acid resistant so that the compound can remain reliable when used in all types of water.
