Description
8101377-3 2 skvalpning av mediet på grund av ökning i luftens lagrade energi vid hylsbristning. _ Uppfinningen syftar sålunda till att erbjuda en vals med variabel bombering. vilken kan begagnas i valsverk, där uto- mordentligt höga belastningar tenderar att uppträda. Luft skall lätt kunna evakueras från denna vals, då mediet införes i densamma. 8101377-3 2 swelling of the medium due to an increase in the stored energy of the air during sleeve rupture. The invention thus aims to provide a roller with variable bombardment. which can be used in rolling mills, where extremely high loads tend to occur. Air must be easily evacuated from this roller when the medium is introduced into it.
En vals med variabel bombering enligt uppfinningen upp- visar en axiell borrning förd från var och en av axelns ändar och in till 1 närheten av radialplanen för början respektive slutet på den ringformiga kammaren, varvid de inre ändarna av de axiella borrningarna genom förbindningsborrningar är för- bundna med början respektive slutet på den ringformiga kamma- ren, samt varvid den andra axiella borrningen vid axelns ände bildar ett tillslutbart utlopp för tryckmediet, vilket utlopp tjänar såsom avluftningsöppning.A variable bearing roller according to the invention has an axial bore carried from each of the ends of the shaft and into the vicinity of the radial plane of the beginning and the end, respectively, of the annular chamber, the inner ends of the axial bores being connected by connecting bores. bonded with the beginning and the end, respectively, of the annular chamber, and wherein the second axial bore at the end of the shaft forms a closable outlet for the pressure medium, which outlet serves as a vent opening.
Då det trycköverförande mediet (exempelvis olja, vatten eller fett) införes i valsen med variabel bombering enligt uppfinningen, placeras valsen lutande eller upprätt med medie- tillförselpassagen nedåt och medieutloppspassagen uppåt, in- föres mediet i valsen genom tillförselpassagen, medan luft i hålrummet och passagerna evakueras samt pluggas utloppspassa- gens mynning, sedan mediet införts.When the pressure-transmitting medium (for example oil, water or grease) is introduced into the variable bombing roller according to the invention, the roller is placed inclined or upright with the media supply passage downwards and the media outlet passage upwards, the medium is introduced into the roller is evacuated and the mouth of the outlet passage is plugged, after the medium has been introduced.
Den enda figuren visar ett längdsnitt genom en vals med variabel bombering enligt uppfinningen, Den i figuren visade utföringsformen av en vals med vari- abel bombering enligt uppfinningen innefattar en axel l och en hylsa 2, som är krymppassad på axeln l. Mellan axeln och hyl- san finnes en ringformig kammare 3 av på förhand bestämt djup.The only figure shows a longitudinal section through a variable bombing roller according to the invention. The embodiment shown in the figure of a variable bombarding roller according to the invention comprises a shaft 1 and a sleeve 2, which is crimped on the shaft 1. Between the shaft and the sleeve - there is an annular chamber 3 of predetermined depth.
Kammarens 3 ena ände är i förbindelse med en axiell medie- tillförselpassage 5 vid axelns l ena ände genom en radiell passage 4 i axeln l, medan kammarens 3 andra ände är i förbin- delse med en medieutloppspassage 7, som är anordnad axiellt vid axelns l andra ände, genom en radiell passage 6 i axeln 1.One end of the chamber 3 is connected to an axial media supply passage 5 at one end of the shaft 1 through a radial passage 4 in the shaft 1, while the other end of the chamber 3 is connected to a media outlet passage 7, which is arranged axially at the shaft 1 other end, through a radial passage 6 in the shaft 1.
En konventionell rotationsled 52 är anbragd vid ett inlopp 51 till medietillförselpassagen 5. Det trycköverförande mediet, exempelvis vatten, olja eller fett. tvingas genom den roterande leden 52 och in i medietillförselpassagen 5, den 8101377-3 3 radiella passagen 4, kammaren 3, den radiella passagen 6, samt en axiell medieutloppspassage 7. Medan mediet tfingas in i valsen, evakueras luft i passagerna och L kammaren genom ett utlopp 71. När medlet nått utloppet 71, tíllslutes detta tätt med en konventionell plugg 72.A conventional rotary joint 52 is arranged at an inlet 51 to the media supply passage 5. The pressure-transmitting medium, for example water, oil or grease. forced through the rotating joint 52 and into the media supply passage 5, the radial passage 4, the chamber 3, the radial passage 6, and an axial media outlet passage 7. While the medium is forced into the roller, air is evacuated into the passages and the L chamber through an outlet 71. When the means has reached the outlet 71, it is tightly closed with a conventional plug 72.
