Abstract
Description
505 762 2 går från drivmaskinen till propellern och på vilken en bussning 4a är uppdragen. 505 762 2 goes from the drive machine to the propeller and on which a bushing 4a is mounted.
För tätning av fartygsaxeln 4 respektive bussningen 4a gentemot yttervattnet W tjänar en tâtningsanordning 5 med ett vid bord- läggningen 2 fastsatt flerdelat bârsystem 5, 5a, 5b vilket inne- håller en huvudtätning 6 såväl som en reservtätning 8.For sealing the ship's shaft 4 and the bushing 4a relative to the outer water W, a sealing device 5 with a multi-part support system 5, 5a, 5b attached to the boarding 2 serves, which contains a main seal 6 as well as a spare seal 8.
Huvudtätningen 6 är utformad såsom glidringstätning och är i överensstämmelse därmed, på konventionellt sätt, utrustad med en glidring 6c som är inspänd mellan en med bussningen 4a förbunden ring 6a och en med bärsystemet förbunden motring 6b. Dessutom är huvudtätningen.6 vid det illustrerade utföringsexemplet utrustad med en uppblåsbar, statisk hjålptätning 7 vilken i fall av behov är aktiverbar medelst ett tryckmedium. Vid bortfall av huvudtât- ningen 6 tjänar reservtätningen 8 såsom nödtätning och den är såsom axeltâtning utrustad med en packboxgland 13 och med mjuka tätningar 14. Packboxglanden 13 är axiellt förskjutbar i förhål- lande till en ringformig styrkropp 11, vilken via ett distans- stycke 10 är styvt förbunden med bârsystemet Sa, 5b. Packbox- glanden 13 är utvändigt försedd med en ringfläns 13a i vilken làmpligtvis en mångfald, i föreliggande utföringsexempel åtta, cylindriska fördjupningar l3b är upptagna, vilka år likformigt fördelade över en cirkellinje. Styrkroppen 11 är försedd med ett motsvarande antal, dvs i föreliggande fall med åtta, i cylind- riska fördjupningar lla insatta kolvar llb, vilka samverkar med fördjupningarna 13b i form av kolv-cylinderenheter.The main seal 6 is designed as a sliding ring seal and is accordingly, in a conventional manner, equipped with a sliding ring 6c which is clamped between a ring 6a connected to the bushing 4a and a counter ring 6b connected to the support system. In addition, in the illustrated embodiment 6, the main seal 6 is equipped with an inflatable, static auxiliary seal 7 which, if necessary, can be activated by means of a pressure medium. In the absence of the main seal 6, the spare seal 8 serves as an emergency seal and it is equipped as a shaft seal with a stuffing box gland 13 and with soft seals 14. The stuffing box gland 13 is axially displaceable in relation to an annular guide body 11, which via a spacer 10 is rigidly connected to the support system Sa, 5b. The stuffing box gland 13 is externally provided with an annular flange 13a in which, suitably, a plurality of, in the present exemplary embodiment eight, cylindrical depressions 13b are accommodated, which are uniformly distributed over a circle line. The guide body 11 is provided with a corresponding number, i.e. in the present case with eight pistons 11b inserted in cylindrical depressions 11a, which co-operate with the depressions 13b in the form of piston-cylinder units.
I cylinderkamrarna till dessa kolv-cylinderenheter är vid varje tillfälle en grenledning l7a till en tryckledning 17 inledd, vilken är ansluten till en tryckkâlla 18 som leder ett hydrau- liskt eller pneumatiskt tryckmedium. Tryckledningen 17 är vidare ansluten till en tryckledning 19 vilken mynnar i yttervattnet W och i vilken ett tryckregleringsorgan 15 är inkopplat, vilket arbetar så att vid ökande tryck hos yttervattnet W stiger tryck- mediets tryck i motsvarande grad, och omvänt. Mellan bärsystemet Sa, 5b och ringflànsen 13a hos packboxglanden 13 är vidare en 505 762 3 áterstâllningsanordning 16 inkopplad, vilken åtminstone består av en skruvfjäder l6a och en med denna samverkande stötslid 16b, varvid skruvfjâdern l6a är lagrad i bärsystemet Sa, 5b och varvid stötsliden l6b med sin fria ände är förbunden med ringflânsen 13a. Skruvfjäderns l6a återställningskraft är dimensionerad så att den vid en sänkning av tryckmediets tryck vid varje tillfälle förflyttar packboxglanden 13 till lösgöringslâget och därmed avlastar dess mjuka packningar eller tätningar 14. Vidare före- ligger en instâllningsanordning 9, vilken är inkopplad mellan styrkroppen 11 och distansstycket 10 och vilken består av en gängad mutter 9a som är lagrad vridbar i ett urtag i styrkroppen 11 men axiellt icke förskjutbart, och vilken med en gänga 10a samverkar med distansstycket 10.In each case, in the cylinder chambers of these piston-cylinder units, a branch line 17a to a pressure line 17 is initiated, which is connected to a pressure source 18 which conducts a hydraulic or pneumatic pressure medium. The pressure line 17 is further connected to a pressure line 19 which opens into the outer water W and in which a pressure regulating means 15 is connected, which works so that with increasing pressure of the outer water W the pressure of the pressure medium rises correspondingly, and vice versa. Between the support system Sa, 5b and the annular flange 13a of the stuffing box gland 13 a resetting device 16 is further connected, which at least consists of a coil spring 16a and a shock slide 16b cooperating therewith, the coil spring 16a being mounted in the support system Sa, 51b and with its free end is connected to the annular flange 13a. The restoring force of the coil spring 16a is dimensioned so that when the pressure of the pressure medium is lowered at each time, it moves the stuffing box gland 13 to the release position and thereby relieves its soft gaskets or seals 14. Furthermore, there is an adjusting device 9 which is connected between the guide body 11 and the spacer which consists of a threaded nut 9a which is mounted rotatably in a recess in the guide body 11 but axially non-displaceable, and which cooperates with a thread 10a with the spacer 10.
Denna manuellt manövrerbara instållningsanordning tjänar å ena sidan såsom säkring när den uppblásbara kroppen blir otät eller vid bortfall av tryckkàllan, och tjänar å andra sidan såsom justeranordning för hela reservtätningssystemets grundstâllning.This manually operable adjusting device serves on the one hand as a safety device when the inflatable body becomes leaky or in the event of a loss of the pressure source, and on the other hand serves as an adjusting device for the basic position of the entire spare sealing system.
