a corredo di una domanda di brevetto per invenzione dal titolo: accompanying a patent application for an invention entitled:
"Dispositivo di protezione a precamera per guarnizioni di tenuta anulari a scorrimento" "Pre-chamber protection device for sliding annular seals"
RIASSUNTO SUMMARY
Dispositivo di protezione a precamera per. guarnizioni di tenuta anulari a scorrimento,in parti di carrelli rotanti di macchine edili contro corpi estranei che penetrano dalle fessure, in cui lo spazio esistente tra la guarnizione di tenuta anulare a scorrimento e il campo periferico della macchina ? riempito con un lubrificante oastoso ed ? chiuso verso l'esterno da un anello di usura collocato in modo flottante in esso. Pre-chamber protection device for. sliding annular seals, in parts of rotating carriages of construction machinery against foreign bodies penetrating through the slots, in which the space existing between the sliding annular seal and the peripheral field of the machine? filled with an oasty lubricant and? closed outwards by a wear ring floating in it.
L'invenzione concerne un dispositivo di protezione a precamera oer guarnizioni di tenuta anulari a scorrimento in parti di carrelli rotanti di macchine edili contro corpi estranei che penetrano dalle fessure. The invention relates to a prechamber protection device for sliding annular seals in parts of rotating carriages of construction machines against foreign bodies penetrating through the slots.
Le parti dei carrelli di macchine edili sono soggette, a causa del loro impiego, a soorcarsi molto. Durante i movimenti di marcia e in oarticolare durante i movimenti rotatori dell'appar?cchio di lavoro vengono compresse, in questo caso, particelle di sporcizia ad alta pressione in cavit? e fessure rese necessarie da motivi costruttivi? In questo modo le guarnizioni di tenuta ad anello scorrevole incorporate in ruote direttrici, carrucole di guida e ruote portanti sono in grande misura danneggiate, cosache provoca svantaggiosamente piccole durate utili di queste parti? Un notevole miglioramento di questa circostanza sarebbe quindi possibile se si riuscisse ad evitare la penetrazione dei corpi estranei e il loroavanzamento fino alle guarnizioni di tenuta ad anello scorrevole? Per? essi portano alla distruzione delle guarnizioni di tenuta ad anello scorrevole tra le parti rotanti, per cui dopo ne consegue una irrevocabile fuoriuscita dell'olio previsto per motivi di lubrificazione? Due to their use, parts of construction machinery trolleys are subject to a lot of wear. During the travel movements and in particular during the rotational movements of the work device, in this case, dirt particles are compressed at high pressure in the cavity. and cracks made necessary for constructive reasons? In this way the sliding ring seals incorporated in guide wheels, guide pulleys and bearing wheels are greatly damaged, which disadvantageously causes short service life of these parts? A considerable improvement of this circumstance would therefore be possible if it were possible to avoid the penetration of foreign bodies and their advancement up to the sliding ring seals? For? they lead to the destruction of the sliding ring seals between the rotating parts, so that afterwards there is an irrevocable leakage of the oil foreseen for lubrication reasons?
Il compito dell?invenzione consiste nell'evitare, per 1'ottenimento di tempi utili pi? lunghi per le guarnizioni di tenuta ad anello scorrevole, la penetrazione di materiali solidi, come l? sabbia, minerali e simili verso le piste e gli anelli di tenuta della guarnizione di tenuta ad anello scorrevole Allo stesso tempo si deve assicurare che questo obiettivo venga salvaguardato quando, ad esempio, a causa dell'usura o di deformazioni elastiche, le fessure e aperture originariamente piccole aumentano di dimensione Una soluzione del compito precedente, nel sistema di protezione descritto avanti, sta nel fatto che il vano della fessura esistente tra la guarnizione di tenuta ad anello scorrevole e il campo periferico della macchina ? riempito con un lubrificante pastoso ed ? chiuso verso l'esterno da un anello di usura, collocato in modo flottante in esso? The task of the invention consists in avoiding, in order to obtain useful times, more? long for the sliding ring seals, the penetration of solid materials, such as l? sand, minerals and the like to the raceways and sealing rings of the sliding ring seal.At the same time it must be ensured that this objective is safeguarded when, for example, due to wear or elastic deformations, cracks and openings originally small they increase in size A solution of the previous task, in the protection system described above, lies in the fact that the space of the gap existing between the sliding ring seal and the peripheral field of the machine? filled with a pasty lubricant and? closed outward by a wear ring, floating in it?
L'anello di usura pu? essere fissato, in questo caso, in modo noto nella sua posizione mediante un anello elastico oppure anche mediante accoppiamento geometrico? Esso deve presentare una minore resistenza all'usura delle parti di parete che lo avvolgono per evitare che si restringa in essa. The wear ring can? be fixed, in this case, in a known way in its position by means of an elastic ring or also by means of positive coupling? It must have a lower resistance to wear than the parts of the wall that surround it to prevent it from shrinking in it.
E? vantaggioso, inoltre, disporre l'anello di usura nel vano della fessura in modo da poter cambiare posizione allo scopo di potersi adattare, in caso di pervenuta variazione della larghezza della fessura, ad essa nella posizione del suo profilo di sezione trasversale? AND? Furthermore, it is advantageous to arrange the wear ring in the slot compartment so as to be able to change its position in order to be able to adapt to it in the position of its cross-sectional profile in the event of a variation in the width of the slot?
L'utilizzazione dello spazio della fessura esistente tra la guarnizione di tenuta ad anello scorrevole e il campo periferico della macchina da parte del dispositivo di protezione a precamera offre, inoltre, la vantaggiosa possibilit? di poter introdurre successivamente, ad esempio in caso di parti dei carrelli danneggiate, in queste una guarnizione supplementare di questo tipo? Con ci? si rendono possibili possibilit? di riparazione o anche di trasformazione? The use of the gap space existing between the sliding ring seal and the peripheral field of the machine by the pre-chamber protection device also offers the advantageous possibility? to be able to subsequently insert an additional seal of this type into these, for example in the case of damaged parts of the carriages? With us? possibilities are made possible? of repair or even transformation?
La quantit? di lubrificante ? dimensionata in modo tale che l'anello di usura viene cinto da esso in modo che ? materiali asportati per sfregamento e i passaggi di piccole particelle di polvere vengano assorbiti dal lubrificante? The quantity of lubricant? dimensioned in such a way that the wear ring is encircled by it so that? materials removed by rubbing and the passages of small dust particles are absorbed by the lubricant?
Tali particelle estranee non possono pi? penetrare, quindi, sotto gli anelli di tenuta, rovinarle e infine pregiudicare la tenuta stagna della camera dell'olio lubrificante? Such foreign particles can no longer? therefore, penetrate under the sealing rings, damage them and finally affect the tightness of the lubricating oil chamber?
L'invenzione viene illustrata pi? dettagliatamente in seguito con riferimento ad esempi di esecuzione rappresentati schematicamente nei disegni? In essi : The invention is illustrated more? in detail hereinafter with reference to exemplary embodiments schematically represented in the drawings? In them:
La figura 1 mostra il rullo di sostegno di per se noto di un carrello di macchina edile? Le guarnizioni di tenuta a scorrimento (1, 2) tra l'albero (3) fisso e il rullo (4) vengono alimentate con il flusso d'olio (6) tramite tubazioni (5)? Figure 1 shows the per se known support roller of a construction machine trolley? Are the sliding seals (1, 2) between the fixed shaft (3) and the roller (4) supplied with the oil flow (6) through pipes (5)?
Per separare l'albero fisso (3) e il rullo mobile (4) si rende necessaria, quindi, partendo dalla guarnizione di tenuta ad anello scorrevole (1, 2), una fessura verso l'esterno che porta allo spazio ambientale? Attraverso una tale fessura, cos? si h rivelato nella pratica, avanzano quindi, durante l'impiego operativo della macchina edile, finissime particelle estranee in direzione delle guarnizioni di tenuta ad anello scorrevole (1, 2), distruggono il film dell?olio presente sulla superficie degli anelli scorrevoli (7, 8) e quindi detti anelli stessi? Il flusso di olio (6) per la lubrificazione del cuscinetto del rullo di sostegno si perde attraverso la fessura? Per cui avviene la distruzione del cuscinetto? To separate the fixed shaft (3) and the movable roller (4) is it therefore necessary, starting from the sliding ring seal (1, 2), an outward slot that leads to the environmental space? Through such a crack, so? has proved in practice, therefore, during the operational use of the construction machine, very fine foreign particles advance in the direction of the sliding ring seals (1, 2), destroying the oil film present on the surface of the sliding rings (7 , 8) and therefore said rings themselves? Is the oil flow (6) for lubricating the support roller bearing leaking through the gap? So the bearing is destroyed?
Secondo l'invenzione ci? viene evitato attraverso uno spazio di fessura (9) e riempiendo detto spazio con un lubrificante pastoso nonch? chiudendo detto spazio verso l'esterno con un anello di usura (10). Quest'ultimo pu? essere fissato, come rappresentato, nella sua posizione, in modo noto, con un anello elastico (11)? According to the invention there? is avoided through a slot space (9) and filling said space with a pasty lubricant as well as? closing said space towards the outside with a wear ring (10). The latter can? be fixed, as shown, in its position, in a known way, with an elastic ring (11)?
La figura 2 mostra un rullo di sostegno analogo, in cui la funzione corrispondente all'anello di usura e assunta da un anello a tazza (12)? Se questo, inizialmente, assume ancora la posizione rappresentata, allora un materiale asportato .per sfregamento pu? fare in modo che esso si abbassi nel vano della fessura chiudendolo, quindi, anche in modo sicuro? Anche in caso di variazioni del vano della fessura, ad esempio tramite usura, un tale anello a tazza ? in grado di adattarsi, nella funzione dell'anello di usura, mediante variazione della posizione? Figure 2 shows a similar support roller, in which the function corresponding to the wear ring is assumed by a cup ring (12)? If this, initially, still assumes the position represented, then a material removed by rubbing can? to make it lower into the slot compartment, thus closing it securely too? Even in the event of changes in the slot space, for example due to wear, such a cup ring? able to adapt, in the function of the wear ring, by changing the position?
L'anello di usura (10) nella figura 1 non ? solo collocato in modo flottante, ma ? annegato completamente nel lubrificante. L'anello a tazza (12) nella figura 2 presenta, invece, soltanto un sistema di supporto flottante. The wear ring (10) in Figure 1 is not? only placed in a floating way, but? drowned completely in lubricant. The cup ring (12) in Figure 2, on the other hand, has only a floating support system.
