Definitions
- normally cable glands comprising one or more badges in the form of a ring, graphite asbestos, contained in a body concentric to the axis, which are pressed against the shaft of rotating propeller.
- This water which penetrates inside the hull must be evacuated.
- the cable gland is rigidly mounted to the shell, it transmits all vibrations from the propeller shaft to the hull itself.
- propeller the engine coupling, the cable gland and the propeller chair. Since this is a structure which is not a rigid monoblock machined at the same time in a single piece, perfect alignment is almost impossible, so the transmission axis never works in the optimal condition, therefore having a high resistance to rotation, due not only to the action braking of the badge, but due to the forcing of the transmission, consequent to the impossibility of perfect alignment.
- Another sealing device normally used in some boats is in a rotary joint consisting of a disc which rotates with the shaft, pushed by a spring against another disc covered with an anti-friction material (graphite, etc.) attached to the hull.
- an anti-friction material graphite, etc.
- Second common problem is the passage of water, more or less important, according to the type: the cable gland lets the water pass clearly, the rotating joint is waterproof only when new, but at the smallest degradation of the runway friction, it lets the water pass either with the axis in rotation than when stopped.
- the present invention consists of a two-stage seal, completely waterproof: it does not allow any drop of water to pass, nor when the axis propeller turns, nor when it is stopped.
- the two floors, one after the other, constitute two impassable dams for water.
- It is a cylindrical case freely fitted on the propeller shaft, which hermetically closes the opening of the hull by means of a trunk of elastic tube in the form of a bellows fixed on the outside of the case itself and the opening of the shell: while inside, in correspondence with the axis, front, it has an annular stop chamber filled with sealing material consisting of grease insoluble viscous which prevents water from passing through the socket-axis gap, without causing friction or mechanical consumption.
- the second stage consists of the oil chamber, which contains the bronze cushion.
- Fig. .1 is a longitudinal section, in which a normal boat is schematized, with a transmission shaft 2, which passes through the shell 1 through the orifice 3 surrounded by the tube trunk 4 integral with the hull.
- the bronze bushing 11 (contained in the cylindrical case 9) is freely fitted on the axis propeller 2, allowing it to either rotate freely, than to slide in axial shape, without offering resistances due to misalignments which force and increase the fiction.
- the bronze bushing of the present invention allows the shaft on which it is mounted to rotate freely, without causing any resistance, either to radial movement or to axial movement, also thanks to the forced lubrication system that will be exposed immediately.
- the cylindrical case 9 On the bronze bushing 11 is pressure mounted among elastic rings O ring 10 and 14, the cylindrical case 9. On this one is fixed one end of a trunk of elastic tube in the form of elastic bellows 5; while the other end is fixed to the tube trunk 4 which surrounds the orifice 3 of the hull (through which the propeller shaft comes out) So the water which penetrates through the orifice on the shell, is contained by the trunk of elastic tube in the form of a bellows, by the shaft, and by the annular stop chamber 16 of the cylindrical case 9, full of sealing material constituted by insoluble viscous fat.
- the cylindrical case 9 is concentric with the shaft and has an opening in the front part with a diameter just greater than that of the tree: enough to avoid rubbing on the tree. After the initial hole, the inside diameter of the case increases, thus forming the annular chamber of blocking 16, delimited at the bottom by the retaining ring 18.
- the annular blocking chamber 16 is filled with the viscous sealing element constituted preferably by insoluble fat which, having a specific weight less than water, is constantly maintained in pressure by the hydrostatic thrust, thus remaining constipated against walls of the annular blocking chamber 16, against the retaining ring 18, and against the shaft 2; thus preventing any passage of water inside the annular blocking chamber.
- the viscous sealing element constituted preferably by insoluble fat which, having a specific weight less than water, is constantly maintained in pressure by the hydrostatic thrust, thus remaining constipated against walls of the annular blocking chamber 16, against the retaining ring 18, and against the shaft 2; thus preventing any passage of water inside the annular blocking chamber.
- the viscous sealing element is introduced at the start into the blocking chamber, among the Stauffer 8 lubricator which fills the entire chamber 16 with grease, eliminating air from the valve purge 17.
- the cylindrical case 9 is preferably made of thermal conductive metal, withstand the corrosion (e.g. bronze or stainless steel). Said case is supported inside by the pad in bronze 11 in anti-friction material, content necessarily concentric on two elastic rings of rubber (O ring) 10 and 14.
- the bronze bushing Il - lubricated by forced circulation of oil on the shaft - supports and guides the cylindrical case 9, keeping it always concentric and parallel to the axis on which it is mounted, axis which can rotate freely, thanks to the lubrication provided by the oil 23 contained in the reservoir 24, among the supply tubes 31b fixed on the barbed ends 13b screwed onto the cylindrical case 9.
- Lubrication continuity is very important and should never be missed either in the bearing bronze on the shaft, and above all with elastic asymmetrical lip retaining rings for shafts turning points.
- the oil tank 24 is placed at a height higher than the water level, so as to exert a higher oil pressure in the chamber of the bronze bushing 11, to contrast and block the tendency for permeability of the sealant grease through the retaining ring unidirectional 18.
- Asymmetrical lip retaining rings for rotating shafts with elastic lip in elastomer are unidirectional. So they block any outflow of oil in one direction, while that in the other direction they allow the passage.
- the oil tank 24 is placed at a height greater than the level of the external water, seen from the specific pea difference between oil and water. In this way the push of the outside water on the sealing element is less than the oil back pressure, so as to avoid the permeability of the sealing element in oil through the unidirectional retaining ring 18, because it could affect the lubricating qualities of the oil.
- the elastic tube trunk in the form of a tubular bellows 5 consists of a very thin rubber or by another elastomer resistant to oils and seawater.
- the elastic trunk of bellows-shaped tube must be tubular 5 or very thin walls. But in this case the elastic tube trunk in the form of a bellows therefore does not offer any guarantee of resistance to torsion, therefore any improvised friction increase of the bronze bushing on the axis (for example: due to a external accident which could cause the loss of oil and the blocking of the bronze bushing 11) could cause the thin rubber of the elastic tube-shaped trunk to tear bellows, causing a very large and very dangerous entry of water.
- FIG. 2 illustrates a sectional view transverse anti-rotation device, constituted - by way of example - by a plate 39 fitted loose on the grooved end piece 20.
- a plate 39 fitted loose on the grooved end piece 20.
- non-limiting anti-rotation device is constituted by the section 38 fixed. to the hull, and with a hole wedged around the barbed end piece 13 which is butted.
- an oil level sensor 21 (Fig. 1) can be introduced into the oil tank 24 which, in in the event of a drop in the oil level, first intervenes with a bell, and then stops the engine.
- an oil pump has been produced incorporated in the same bronze bushing 11, and that not only uses the rotary motion of the axis on which it is mounted, but it uses the axis even, as the basic organ of this very original pump.
- Fig. 3 shows the oil tank 24, from which the two supply pipes 31b, attached on the barbed ends 13b. These barbed ends are screwed onto the case 9, and allow the oil to enter which in its passage lubricates the lips of the asymmetrical lip retaining rings unidirectional in elastomer 18 and 33.
- the oil continues its way and passes through the tunnels 32 (see also Fig. 5) of the bronze bushing 11, where it constantly lubricates the axis which turns in the bronze bushing (see also Fig. 4 and 5) by entering the space between the axis and the bronze bushing, thus forming a thin layer of intermediate oil that separates the two metals. So this intermediate layer prevents the friction of metals by preserving them from wear.
- the oil is dragged by the axis in its rotation, by the phenomena of "surface tension” and “sticking of a viscous liquid to a solid (the axis)", and it is compressed towards the constriction of the eccentric room.
- a small part of oil is threaded between the axis and the portion with the diameter almost adherent to the same, forming the intermediate layer which guarantees lubrication and prevents direct contact between the two metals, preserving them from wear.
- the excess of oil which does not manage to get between the axis and the bronze, accumulates near strangulation which causes an increase in pressure.
- Fig. 7 shows the example of application of the seal on a worn shaft of a boat former.
- the shaft has the wear 50 caused by the friction of the bademe of a cable gland traditional.
- a rigid tube trunk 51 with an internal diameter is mounted. slightly higher than that of the tree.
- the tube trunk is supported concentric to the axis by the sleeve 52.
- the tube trunk is wedged concentric to the axis, by the bush 53, blocked by the screw 55.
- the bush is blocked at the shaft by the screw 58, so the tube trunk turns integral with the axis.
- O-Rings 54 and 57 prevent the passage of water which could infiltrate through the socket 52 between the shaft and the inside of the tube trunk 51.

Description
- a) Etanchéité totale grâce aux deux étages, formant deux barrages infranchissables à l'eau, disposes l'un après l'autre, constitués le premier par la chambre à graisse comprimée par la poussée hydrostatique et le deuxième par la chambre à huile à contre-pression où est logé le coussinet en bronze.
- b) Etanchéité totale dans le temps, car après plusieurs milliers d'heures de fonctionnement, si les lèvres des bagues de retenue devaient s'user, va se vérifier tout au plus une petite fuite d'huile - récupérable - à l'intérieur du bateau, par contre il n'y aura jamais aucune entrée d'eau. Donc à ce moment on pourra ajouter l'huile récupérée et programmer la simple substitution des bagues de retenue à lèvre élastique.
- c) Coefficient de friction extrêmement bas, dû à:
- parfaite lubrification forcée continue du coussinet en bronze
- parfaite lubrification forcée continue des lèvres des bagues de retenue
- JOINT D'ETANCHEITE flottant et toujours auto-aligné à l'axe, car il est simplement emboíté sur l'arbre, maintenu à sa place par le dispositif anti-rotation, exempte de fixations rigidés.
- d) Grâce au coefficient de friction extrêmement bas obtenu, il n'y a aucun effet de freinage, donc aucun gaspillage de puissance motrice: économie d'exercice et plus grande vitesse du bateau.
- e) Système de circulation forcée d'huile simple, fiable, économique et inusable.
- f) Lubrification et refroidissement obtenus sans eau, rendent indispensable la présente invention sur les bateaux à haute vitesse, où se forme le vide d'eau.
- g) Grâce au système de lubrification forcée continue, à la conception de montage sans fixations rigides que provoquent des forçages sur l'arbre et au coefficient de friction extrêmement bas, l'axe ne subit aucune usure dans le temps, constituée par la formation de profonds sillons. En effet, la possibilité de coulisser axaient sur l'arbre en forme continue, avec un petit déplacement équivalent an petit jeu du trou 38 ou 39 sur la saillie 20 (de Fig. 2) du dispositif anti-rotation, provoqué par le mouvement de va et vient imperceptible déterminé par les vibrations du moteur (fixé normalement sur des supports élastiques en caoutchouc vulcanisé), fait que les lèvres élastiques des bagues de retenue 18 et 33, tournent toujours sur une surface constamment lubrifiée, aussi comme le coussinet en bronze. Cela contribue aussi à empêcher toute formation de sillons sur la surface de l'axe.
- h) Le système constructif visé à n'utiliser aucun disque ou bague fixé à l'arbre, pour permettre la possibilité de coulissement de l'axe; combine avec le dispositif d'arrêt en cas de déplacement anomal de l'arbre, il prévient contre éventuels accidents. (Les joints tournants qu'on trouve sur le marché, n'ont pas eu grand succès, car ils n'offrent la garantie de déplacement axial de l'arbre).
- i) Le système anti-rotation, outre à être une sécurité qui prévient éventuels accidents, permette la flottabilité maximale; donc il permette le fonctionnement même sur des arbres tordus, mals alignés et même dans le cas qu'ils ne sont pas concentriques au trou de sortie dans la coque.
- l) L'option du tronc de tube rigide permette l'utilisation sur des axes usés et abímés.
- m) Le tait que l'étui calé à pression sur le coussinet en bronze de soutien parmi les deux bagues élastiques O ring, garantit la sécurité maximale, même dans le cas rarissime d'un accident étranger qui p.e. pourrait arriver à couper les tubes à huile et provoquer le grippage du coussinet en bronze. Même dans ce cas rarissime le JOINT D'ETANCHEITE continuerait à fonctionner provisoirement jusqu'à la réparation.
