Den foreliggende opfindelse angår et nedre leje til en skibsrorstamme, hvor akslen eller lejet tillades at udføre aksial-, dreje- og vippebevægelse.The present invention relates to a lower bearing for a ship rudder stem where the shaft or bearing is allowed to perform axial, pivotal and tilting movements.
5 Nedre lejer til skibsrorstammer har i hovedsagen været udformet som omdrejningscylindriske lejer, der tillader rotation og forskydning i aksialretningen.5 Lower bearings for ship rudder strains have essentially been designed as rotary cylindrical bearings which allow rotation and shear in the axial direction.
Ved store belastninger på roret og derved sideværts mod ror-10 akslen vil der i det nedre leje opstå et bøjningsmoment, der medfører at rorakslen med betydelig kraft sideværts påvirker lejets øvre og nedre modsat beliggende kanter. Rorakslen vil mellem et øvre og det nedre leje indtage en bueformet linie beliggende uden for sin teoretiske lodrette akse. Samtidig vil 15 rorakslen løftes under lodret bevægelse og skråstilles i det nedre leje.At high loads on the rudder and thereby laterally towards the rudder shaft, a bending moment will occur in the lower bearing, which causes the rudder shaft to influence the upper and lower opposite edges of the bearing with considerable force laterally. Between the upper and lower bearings, the rudder shaft will take an arcuate line located outside its theoretical vertical axis. At the same time, the rudder shaft will be lifted during vertical movement and tilted in the lower bearing.
De kendte omdrejningscylindriske lejer tillader naturligt en forskydning i rorstammens længderetning, men imidlertid er le-20 jet ikke konstrueret til at optage de uheldige kræfter, som bl.a. hidrører fra de store belastninger sideværts på roret. Dette betyder, at de kendte omdrejningscylindriske lejer er udsat for stort slid og ekstreme belastninger.The known rotational cylindrical bearings naturally allow a displacement in the longitudinal direction of the rudder stem, however, the bearing is not designed to absorb the unfortunate forces which, among other things, stems from the large loads lateral to the helm. This means that the known rotary cylindrical bearings are subject to excessive wear and extreme loads.
25 Formålet med den foreliggende opfindelse er derfor at tilvejebringe et nedre leje til en skibsrorstamme, hvor akslen eller lejet tillades at udføre aksial-, dreje- og vippebevægelse, og hvor der undgås de ovenfor nævnte hidtil kendte ulemper.The object of the present invention is therefore to provide a lower bearing for a ship rudder trunk where the shaft or bearing is allowed to perform axial, pivotal and tilting movements and avoids the aforementioned disadvantages known above.
30 Det nedre leje til en skibsrorstamme er ifølge opfindelsen ejendommeligt ved, at en rorstamme omsluttende lejebøsning er forsynet med langsgående notgange, som er beliggende overfor i rorstammen tildannede notgange, hvilke notgange er indrettede til at optage fedre for at tillade aksial bevægelse og forhin-35 dre drejebevægelse mellem rorstammen og lejebøsningen, og at lejebøsningen er forsynet med et kugleformet lejeelement, hvis konvekse kugleformede flade ligger an mod og kan bevæges i forhold til en konkav kugleformet flade i en rundt om lejebøs- ningen indrettet ydre lejebøsning, der omfatter to parter, hvoraf en øvre part er fastgjort til skibets skrog.According to the invention, the lower bearing for a ship rudder stem is characterized in that a rudder stem enclosing bearing sleeve is provided with longitudinal grooves located opposite grooves formed in the rudder stem, which grooves are adapted to accommodate fathers to allow axial movement and advance. rotating movement between the rudder stem and the bearing bush, and the bearing bush is provided with a spherical bearing element, the convex spherical surface of which abuts and can be moved relative to a concave spherical surface in an outer bearing bush arranged around the bearing bush, comprising two parts; an upper part of which is attached to the hull of the ship.

Herved opnås, at rorakslen kan skråtstilles i lejet, som følge 5 af en udbøjning af rorakslen fra dens lodrette akse, og samtidig kan rorakslen bevæges i sin længderetning i lejet. Især i forbindelse med et kugleformet øvre leje, der muligvis er forbundet med en drejemotor opnås et ideelt nedre leje til rorstammen indrettet til at optage lejekræfterne, der opstår på 10 grund af store belastninger på roret, idet den heraf følgende skråstilling samt eventuelt aksialforskydning af rorstammen optages fuldstændig i lejerne.Hereby it is obtained that the rudder shaft can be inclined in the bearing as a result of a deflection of the rudder shaft from its vertical axis, and at the same time the rudder shaft can be moved longitudinally in the bearing. Particularly in connection with a spherical upper bearing, possibly connected to a rotary motor, an ideal lower bearing is provided for the rudder stem adapted to accommodate the bearing forces arising from large loads on the rudder, the resulting inclined position and possibly axial displacement of the rudder stem. are completely absorbed in the bearings.
På særlig fordelagtig måde kan ifølge opfindelsen lejebøsnin-15 gens notgange strække sig i en nedre større del af lejebøsningens højde.In a particularly advantageous way, according to the invention, the groove grooves of the bearing bush can extend into a lower part of the height of the bearing bush.
Endvidere kan ifølge opfindelsen lejebøsningens notgange været udformet forløbende kontinuert i lejebøsningens fulde højde.Furthermore, according to the invention, the groove grooves of the bearing sleeve may have been designed continuously continuously at the full height of the bearing sleeve.

Opfindelsen forklares nedenfor under henvisning til tegningen, som viser et aksialsnit gennem det nedre leje. Fastgørelsen af lejet til skibet er ikke vist.The invention is explained below with reference to the drawing, which shows an axial section through the lower bearing. The attachment of the bearing to the ship is not shown.
25 Rorstammen 1 har en part med forøget diameter og en rundtgåen-de notgange 2. En lejebøsning 4 omslutter rorstammen og er forsynet med en eller flere notgange 3, der strækker sig i hele bøsningens højde eller kun i en nedre større del af dens højde , som vist med henvisningstallet 10. Fedre 9 er indsat i 30 notgangene 2 i rorstammen 1 og fanges i notgangen 3 i lejebøsningen 4. Derved kan rorstammen 1 forskydes i aksialretningen, idet fedrene 9 forskydes i lejebøsningens 4 notgange 3 og forbliver i rorstammens 1 notgange 2.The rudder stem 1 has a portion of increased diameter and a circumferential groove 2. A bearing sleeve 4 encloses the rudder stem and is provided with one or more grooves 3 extending throughout the height of the sleeve or only at a lower greater portion of its height. As shown by reference numeral 10. Fathers 9 are inserted into the grooves 2 of the rudder stem 1 and are trapped in the groove 3 of the bearing sleeve 4. Thereby the rudder stem 1 can be displaced in the axial direction, the fathers 9 being displaced in the grooves 4 of the bearing sleeve 4 and remaining in the grooves 1 of the rudder stem 1. .
35 Lejebøsningen 4 er forsynet med et kugleformet lejeelement 5, der for eksempelvis er fremstillet af polyamid med en kugleformet ydre overflade 6. Det kugleformede lejeelement 5 er udformet som to delvis kugleformede ringe, en øvre og en nedre,The bearing sleeve 4 is provided with a spherical bearing element 5, for example made of polyamide with a spherical outer surface 6. The spherical bearing element 5 is formed as two partially spherical rings, one upper and one lower,
