Description
Foreliggende oppfinnelse angår en anordning for lagring av et ledehjul bak en regulerbar skipspropell, idet ledehjulet har samme akse som propellen. The present invention relates to a device for storing a guide wheel behind an adjustable ship's propeller, the guide wheel having the same axis as the propeller.
Slike ledehjul benyttes for å forbedre virkningsgraden til en skipspropell, og er f.eks. kjent fra DE-AS 1756889, og fra DE-OS 3037369 er det dessuten kjent at det er behov for en slik forbedring av virkningsgraden særlig for regulerbare pro-peller med tykt nav. Such guide wheels are used to improve the efficiency of a ship's propeller, and are e.g. known from DE-AS 1756889, and from DE-OS 3037369 it is also known that there is a need for such an improvement in efficiency, particularly for adjustable propellers with a thick hub.
Dersom et ledehjul skal monteres på et eksisterende skip, er det ønskelig at konstruksjonen er så kort som mulig, slik at roret ikke behøver å flyttes bakover. If a guide wheel is to be mounted on an existing ship, it is desirable that the construction is as short as possible, so that the rudder does not need to be moved backwards.
Videre skal i mange tilfeller det deksel som befinner seg bak på navet til en regulerbar propell, og som er en hindring for opplagring av et ledehjul, kunne benyttes på nytt, f.eks. på propellen til et annet skip. Furthermore, in many cases the cover which is located behind the hub of an adjustable propeller, and which is an obstacle for storing a guide wheel, must be able to be used again, e.g. on the propeller of another ship.
Formålet med den foreliggende oppfinnelse er å komme frem til en anordning som muliggjør at disse to vilkår oppfylles. Dette oppnås i henhold til oppfinnelsen med en anordning som angitt i de etterfølgende patentkrav. The purpose of the present invention is to arrive at a device which enables these two conditions to be fulfilled. This is achieved according to the invention with a device as stated in the subsequent patent claims.
Oppfinnelsen skal i det følgende forklares nærmere, under henvisning til de vedføyde tegninger. Fig. 1 viser en anordning i henhold til oppfinnelsen, til-passet formen til akterenden til et skip og roret. Fig. 2 viser en aksel som bærer ledehjulet, samt lager for The invention will be explained in more detail below, with reference to the attached drawings. Fig. 1 shows a device according to the invention, adapted to the shape of the stern of a ship and the rudder. Fig. 2 shows an axle that carries the guide wheel, as well as bearings
ledehjulet og deres tetninger. the guide wheel and their seals.
Fig. 1 viser en skipshekk 1 med et rorblad *J som kan dreies om en rorakse 5 for styring av skipet, idet rorbladetj er dreibart lagret høyere opp i skroget og nederst er tilkoblet en støtte-arm 6. Foran rorbladet 5 er en drivanordning i form av en regulerbar propell 10 med et nav 11 og propellblad 7, som kan dreie om akser i planet 9. Fig. 1 shows a ship's stern 1 with a rudder blade *J which can be rotated about a rudder axis 5 for steering the ship, the rudder blade j is rotatably stored higher up in the hull and a support arm 6 is connected at the bottom. In front of the rudder blade 5 is a drive device in form of an adjustable propeller 10 with a hub 11 and propeller blade 7, which can rotate about axes in the plane 9.
Det deksel som vanligvis befinner seg bak på navet 11 er fjernet, og det er i stedet montert en særskilt aksel 12, som med en ende dekker bevegelsesmekanismen 8 til propellen 10 og med den annen ende danner lagring for ledehjulet 2, som har skovler 3- For fastgjøringen benyttes fire bolter, antydet med en strekpunktlinje 18. Navet 11 har en avtrapning 19 som akselen 12 er ført inn på. The cover which is usually located at the back of the hub 11 has been removed, and instead a special shaft 12 has been mounted, which with one end covers the movement mechanism 8 of the propeller 10 and with the other end forms storage for the guide wheel 2, which has vanes 3- For the fastening, four bolts are used, indicated by a dotted line 18. The hub 11 has a taper 19 on which the axle 12 is guided.
For å oppta radialbelastningen og aksialbelastningen fra ledehjulet 2 benyttes et sfærisk rullelager 14 og et sylindrisk rullelager 15. Det sfæriske rullelager 14 er anordnet bakerst. Derved er det nødvendig å benytte et rullelager med hydraulisk spennhylse. Det sfæriske rullelager 14 og det sylindriske rullelager 15 holdes derved på plass med sine ytter-ringer i ledehjulet 2. På denne måte oppnås en enkel monter-ing og demontering av ledehjulet 2. For å danne tetning mel-lom akselen 12 og navet 13 til ledehjulet er det anordnet et bakre deksel 7- Foran ledehjulet er anordnet en glidetetning 16, som før monteringen av ledehjulet 2 på akselen 12 må monteres på navet 13 til ledehjulet. En ring 20 i tetningen 16 holder samtidig yttérringen til det sylindriske rullelager 15 på plass. Huset 21 som tetningsringen i tetningen 16 anbringes i er utført delt, og skrus fast til akselen 12 slik at de tre tetningsringene utsettes for en klemkraft i aksial retning. A spherical roller bearing 14 and a cylindrical roller bearing 15 are used to take up the radial load and the axial load from the guide wheel 2. The spherical roller bearing 14 is arranged at the rear. Thereby, it is necessary to use a roller bearing with a hydraulic clamping sleeve. The spherical roller bearing 14 and the cylindrical roller bearing 15 are thereby held in place with their outer rings in the guide wheel 2. In this way, a simple assembly and disassembly of the guide wheel 2 is achieved. To form a seal between the shaft 12 and the hub 13 to guide wheel there is a rear cover 7- A sliding seal 16 is arranged in front of the guide wheel, which must be mounted on the hub 13 of the guide wheel before mounting the guide wheel 2 on the shaft 12. A ring 20 in the seal 16 simultaneously holds the outer ring of the cylindrical roller bearing 15 in place. The housing 21 in which the sealing ring in the seal 16 is placed is made split, and is screwed to the shaft 12 so that the three sealing rings are subjected to a clamping force in the axial direction.
