Keksinnön kohteena on laite akselien, erikoisesti liukulaa-keriakselien, keskittämiseksi laakereihin. Sitä voidaan käyttää myös asennus-, kuljetus- ja suoritustarkoituksiin.The invention relates to a device for centering shafts, in particular sliding ball shafts, in bearings. It can also be used for installation, transport and performance purposes.
Vaakasuoraan ja pystysuoraan järjestettyjen akselien, esim. liukulaakeriakselien keskittämiseksi on tapana asentaa pesän ulkoseiniin akselin ulostulokohtiin keskitysrenkaat. Nämä renkaat ovat yleensä kaksiosaisia ja ne on valmistettava jokaiselle halkaisija-koolle sovittamalla. Ne on asennettu uraan ja kiinnitetty useilla ruuveilla pesään. Näiden renkaiden valmistus on kustannuksia vaativaa ja niiden käyttö vaatii asennettaessa ja purettaessa suurta ajankäyttöä. Näitä renkaita paikalleen asennettaessa ei akselia voida kiertää ilman lisätyökaluja ja nostolaitteita. Toisaalta on olemassa vaara, että akseli vahingoittuu hiertymisen johdosta.In order to center the horizontally and vertically arranged shafts, e.g. plain bearing shafts, it is customary to mount centering rings on the outer walls of the housing at the shaft outlets. These rings are usually two-piece and must be made to fit each diameter size. They are mounted in the groove and fastened to the housing with several screws. The manufacture of these tires is costly and their use requires a great deal of time during installation and disassembly. When these tires are fitted, the shaft cannot be rotated without additional tools and lifting equipment. On the other hand, there is a risk that the shaft will be damaged due to abrasion.
Keksinnön tehtävä on poistaa nämä tunnetut haitat ja aikaansaada keskitys-, asennus-, kuljetus-, suoritus- ja varmistinlaite, jota voidaan käyttää yksinkertaisella tavalla akselin halkaisijasta 2 61080 ja kiertosuunnasta riippumatta ilman suuria työstökustannuksia.The object of the invention is to eliminate these known drawbacks and to provide a centering, mounting, transporting, performing and securing device which can be operated in a simple manner, regardless of the shaft diameter 2 61080 and the direction of rotation, without high machining costs.
Tehtävä ratkaistaan siten, että laakeripesässä on rengasmainen, otsasivulle ja akselin keskustaan päin avoin, akselin kanssa samankeskinen syvennys, johon on järjestetty rullaketju, jolla on liikerata akselilla ja syvennyksessä ja joka kannattaa akselia.The task is solved in that the bearing housing has an annular recess, open to the front side and to the center of the shaft, concentric with the shaft, in which a roller chain is arranged, which has a trajectory on the shaft and in the recess and which supports the shaft.
Lisäksi on huolehdittu siitä, että rullaketju on varmistettu aksiaalista, akselilla siirtymistä vastaan.In addition, care has been taken to ensure that the roller chain is secured against axial, axial displacement.
Rullaketjut voidaan asettaa pesien otsasivuun suunnilleen akselin halkaisijaa vastaavina pätkinä. Niitä voidaan käyttää yksipuolisesti tai molemminpuolisesti, yksinkertaisena tai moninkertaisena rullaketjurakenteena.The roller chains can be placed on the front side of the nests in pieces corresponding to approximately the diameter of the shaft. They can be used unilaterally or reciprocally, as a single or multiple roller chain structure.
Karkaistut rullaketjut ovat kauppatavan mukaisia ketjuja, joiden rullien halkaisija on liitosniveliä suurempi. Ne asetetaan pesän otsasivujen uriin ja varmistetaan pidikerenkaalla tai senkaltaisella aksiaalista siirtymistä vastaan. Akseli keskittyy ja samalla rullat kannattavat sitä. Laakerien asennuksen aikana saattaa olla tarpeellista kiertää akseleita laakereissaan, jotta esimerkiksi työntöakselien yksittäiset työntökappaleet voidaan asettaa paikalleen pesän aukkojen läpi. Laakeriakselin kierto voi silloin tapahtua sisään asetetun rullaketjun avulla vaivattomasti ilman mekaanisia tai hydraulisia laitteita ja akselia ja pesää vahingoittamatta vähällä voimalla, tässä tapauksessa käsivoimin.Hardened roller chains are commercially available chains with a larger roller diameter than the joint. They are placed in the grooves on the front sides of the housing and secured with a retaining ring or the like against axial displacement. The shaft is focused and at the same time the rollers support it. During the installation of the bearings, it may be necessary to rotate the shafts in their bearings so that, for example, the individual push pieces of the push shafts can be inserted through the openings in the housing. The bearing shaft can then be rotated effortlessly by means of the inserted roller chain without mechanical or hydraulic equipment and without damaging the shaft and housing with a small force, in this case by hand.
Myös laakeria ja akselia yhdessä kuljetettaessa rullaketju kannattaa akselia, suojaten siten pesän ja akselin kuljetusvahin-goilta.Also when transporting the bearing and the shaft together, the roller chain supports the shaft, thus protecting the housing and the shaft from transport damage.
Kun laitetta käytetään laivoissa, voidaan yksittäiset akselit asettaa laakereissaan koko akselijohdon kytkemistä varten haluttuun asentoon vaivattomasti, tässä tapauksessa ilman kiertolai-tetta. Akselien suoristuksen jälkeen ja ennen niiden lopullista kytkemistä on rullaketjut otettava pois, jotta laakeripesien otsa-sivut vapautuisivat kuormastaan.When the device is used on ships, the individual shafts can be easily positioned in their bearings to connect the entire shaft line to the desired position, in this case without a rotating device. After straightening the shafts and before final coupling, the roller chains must be removed to release the front ends of the bearing housings.
Keksinnön mukaisen laitteen edut ovat erityisesti sen yksinkertaisessa ja taloudellisessa valmistuksessa ja sen loputtomassa ja vaikuttavassa uudelleen käytössä.The advantages of the device according to the invention are in particular its simple and economical manufacture and its endless and effective reuse.
Keksinnön mukainen esine on esitetty piirustuksessa olevassa suoritusmuotoesimerkissä, jossa on: 3 61080 kuviossa 1 akselin ja laakeripesSn väliin järjestetty rulla-ketju ja kuviossa 2 laakeripesän osan pituusleikkaus.The object according to the invention is shown in an exemplary embodiment in the drawing, in which: in Fig. 1 there is a roller chain arranged between the shaft and the bearing housing in Fig. 1 and in Fig. 2 a longitudinal section of a part of the bearing housing.
Laakeripesän 1 otsasivussa 2 on rengasmainen syvennys 3, joka on akselin keskustaan ja otsasivuun päin avoin. Akselin kanssa samankeskiseen syvennykseen 3 on järjestetty rullaketju 4, jolla on liikerata akselilla 5 ja syvennyksen 3 pinnalla 6 ja joka ohjaa ja kannattaa akselia 5. Rullaketju 4 on varmistettu aksiaalista siirtymistä vastaan pidikerenkaalla 7.The end face 2 of the bearing housing 1 has an annular recess 3 which is open towards the center of the shaft and the end side. A roller chain 4 is arranged in the recess 3 concentric with the shaft, which has a trajectory on the shaft 5 and on the surface 6 of the recess 3 and which guides and supports the shaft 5. The roller chain 4 is secured against axial displacement by a retaining ring 7.
Rullaketju 4 on kauppatavan mukaista ketjua, jonka rullien 8 halkaisija on suurempi kuin liitosnivelien 9 ja 10 halkaisija.The roller chain 4 is a conventional chain, the diameter of the rollers 8 being larger than the diameter of the connecting joints 9 and 10.
