“AZIONAMENTO PER CANCELLI O PORTONI” "OPERATION FOR GATES OR DOORS"
DESCRIZIONE DESCRIPTION
L’invenzione si riferisce ad un azionamento per cancelli o portoni. The invention refers to a drive for gates or doors.
I cancelli o i portoni sono spesso spostati da azionamenti elettrici che hanno un involucro a muro dal quale esce un braccio articolato girevole orizzontalmente che trasmette il moto dall' azionamento al cancello o porta o portone. Gates or doors are often moved by electric drives that have a wall casing from which a horizontally rotating articulated arm comes out that transmits the motion from the drive to the gate or door or door.
Attualmente sono commercializzati due diversi tipi di azionamenti caratterizzati da diverse strutture e componenti meccaniche. Currently two different types of drives are marketed characterized by different structures and mechanical components.
La tipologia più comune comprende azionamenti aventi un involucro che contiene il motore elettrico, l' elettronica di gestione ed il riduttore meccanico. Quest’ultimo trasmette il moto al braccio articolato per mezzo di un opportuno albero d’uscita, posto all’estremità inferiore dellazionamento, che movimenta il cancello o portone. The most common type includes drives having a casing that contains the electric motor, the management electronics and the mechanical reducer. The latter transmits motion to the articulated arm by means of an appropriate output shaft, located at the lower end of the drive, which moves the gate or door.
E’ facilmente intuibile, anche se non indispensabile, che il motore elettrico, il riduttore meccanico ed il braccio articolato sono girevoli rispetto al medesimo asse verticale. It is easy to understand, although not essential, that the electric motor, the mechanical reducer and the articulated arm are rotatable with respect to the same vertical axis.
Il motore elettrico è di tipo commerciale, il riduttore meccanico è realizzato secondo tecniche e tecnologie di tipo noto, e l interconnessione dell’albero di uscita del riduttore al braccio articolato è realizzata con particolare cura e particolari materiali perché soggetta a sollecitazioni gravose, dovute al movimento imposto dall’azionamento al cancello oppure a sollecitazioni dell’utente direttamente sul cancello oppure ad agenti atmosferici. The electric motor is of a commercial type, the mechanical reducer is made according to known techniques and technologies, and the interconnection of the reducer output shaft to the articulated arm is made with particular care and particular materials because it is subjected to heavy stresses, due to the movement. imposed by the drive on the gate or to user solicitations directly on the gate or to atmospheric agents.
Altri azionamenti hanno una diversa modalità di interconnessione del riduttore meccanico al braccio articolato. Il motore elettrico ed il riduttore meccanico sono realizzati secondo metodologie note ma l’albero di uscita del riduttore interagisce con la dentatura realizzata allintero dellestremità anulare del braccio articolato, posto nella zona inferiore deH’azionamento. Questo comporta che l’asse di rotazione del motore e del riduttore meccanico è diverso dall’asse di rotazione del braccio articolato. Other drives have a different way of interconnecting the mechanical reducer to the articulated arm. The electric motor and the mechanical reducer are made according to known methods but the output shaft of the reducer interacts with the toothing made throughout the annular end of the articulated arm, located in the lower area of the drive. This means that the axis of rotation of the motor and of the mechanical reducer is different from the axis of rotation of the articulated arm.
Questa costruzione, soprattutto per motori di potenza elevata destinati a spostare pesanti portoni industriali, si dimostra critica nelle prestazioni. Poiché solo un paio di denti del pignone ingranano sulla corona dentata, su tali denti si scarica uno sforzo notevole. Il pignone deve quindi essere realizzato in metallo resistente, e per ciò costoso. Anche la stabilità del braccio articolato ne risente, perché le foize esterne agenti sul braccio stesso, ad es. un urto o vento sul portone, devono essere contrastate eccentricamente dalla corona e dal pignone oltre che dai mezzi di sostegno del braccio articolato. La condizione di eccentricità del pignone inoltre impone l’uso di mezzi di centraggio e/o allineamento e/o sostegno del braccio articolato sull' involucro, che complicano la struttura. This construction, especially for high power motors intended to move heavy industrial doors, proves critical in performance. Since only a couple of teeth of the pinion mesh with the ring gear, considerable strain is placed on these teeth. The pinion must therefore be made of durable, and therefore expensive, metal. Even the stability of the articulated arm is affected, because the external foize acting on the arm itself, eg. a blow or wind on the door, must be eccentrically opposed by the crown and pinion as well as by the means of supporting the articulated arm. The state of eccentricity of the pinion also requires the use of means for centering and / or aligning and / or supporting the articulated arm on the casing, which complicate the structure.
Un esempio di questo tipo di costruzione è descritto nel documento US 5 102 377. An example of this type of construction is described in US 5 102 377.
In entrambi le tipologie di azionamenti, l’aumento di potenza nel motore elettrico e di conseguenza del peso del cancello comportano un adeguamento tecnico strutturale di molte parti meccaniche, ma in particolare dell’interconnessione tra riduttore meccanico e braccio articolato. In entrambi i casi l’interconnessione utilizzerà materiali pregiati e costosi. In both types of drives, the increase in power in the electric motor and consequently in the weight of the gate entail a structural technical adjustment of many mechanical parts, but in particular of the interconnection between the mechanical reducer and the articulated arm. In both cases, the interconnection will use valuable and expensive materials.
Scopo principale dellinvenzione è modificare la nota struttura dell’azionamento per migliorarne le prestazioni, preferibilmente senza l’impiego di materiali pregiati. The main purpose of the invention is to modify the known structure of the drive to improve its performance, preferably without the use of valuable materials.
Ulteriore scopo è che l’asse di rotazione del braccio articolato sia il medesimo deH’albero di uscita del riduttore meccanico. Another purpose is that the rotation axis of the articulated arm is the same as the output shaft of the mechanical reducer.
Ulteriore scopo è migliorare la stabilità del braccio diminuendo ed equilibrando gli sforzi interni, in particolare nell’ interconnessione tra riduttore meccanico e braccio articolato. Another purpose is to improve the stability of the arm by decreasing and balancing the internal efforts, in particular in the interconnection between the mechanical reducer and the articulated arm.
Ulteriore scopo è ridurre i costi di produzione garantendo le dovute prestazioni. Another purpose is to reduce production costs by guaranteeing the necessary performance.
Tali scopi sono raggiunti con un azionamento come definito nella rivendicazione 1, mentre varianti preferite sono definite nelle rivendicazioni dipendenti. These objects are achieved with a drive as defined in claim 1, while preferred variants are defined in the dependent claims.
Il fatto di comprendere uno o più ingranaggi satelliti posti tra un organo di trasmissione (ad es. un pignone), che trasmette il moto rotatorio dell’albero di uscita del motoriduttore (oppure dal riduttore meccanico) alla corona dentata, e la corona dentata stessa in modo da formare un cinematismo di tipo epicicloidale dà molti vantaggi: The fact of comprising one or more planetary gears placed between a transmission member (e.g. a pinion), which transmits the rotary motion of the output shaft of the gearmotor (or from the mechanical reducer) to the crown gear, and the crown gear itself in order to form an epicycloidal type of kinematics gives many advantages:
- usando più di un elemento dentato (almeno due) in impegno sulla corona dentata del braccio si distribuiscono gli sforzi, perché aumenta il numero di denti (almeno due) che contemporaneamente sono in presa sulla corona. Di conseguenza migliora la stabilità del braccio (spinto in almeno due punti) e l’affidabilità dei componenti. Inoltre le ruote dentate possono essere fabbricate in materiale meno pregiato (per esempio plastico), riducendo i costi, alleggerendo la struttura e migliorando l’assorbimento di urti e vibrazioni che dal braccio sono trasmesse all’ azionamento. Usando ingranaggi satelliti di uguali dimensioni si semplifica la produzione; - by using more than one toothed element (at least two) in engagement on the toothed crown of the arm, the stresses are distributed, because the number of teeth (at least two) which are simultaneously engaged on the crown increases. Consequently, it improves the stability of the arm (pushed in at least two points) and the reliability of the components. In addition, the toothed wheels can be manufactured in less valuable material (for example plastic), reducing costs, lightening the structure and improving the absorption of shocks and vibrations that are transmitted from the arm to the drive. Using planetary gears of the same size simplifies production;
- c’è libertà di progetto perché la corona dentata del braccio può essere interna o esterna; - there is freedom of design because the toothed crown of the arm can be internal or external;
.- il cinematismo epicicloidale che si sviluppa con le ruote dentate satelliti ha il notevole pregio di funzionare come sistema di centraggio del braccio e di stabilizzazione, per cui si possono eliminare tutti i componenti dell’arte nota preposti a tali funzioni, con notevole risparmio di costi e miniaturizzando l’azionamento. Ciò si ottiene soprattutto se i centri delle ruote dentate satelliti sono disposti simmetricamente attorno al centro della dentatura del braccio. .- the epicyclic kinematics that develops with the planetary gear wheels has the considerable advantage of functioning as a centering and stabilization system of the arm, so that all the components of the known art in charge of these functions can be eliminated, with considerable savings in costs and miniaturizing the drive. This is achieved above all if the centers of the planetary gears are arranged symmetrically around the center of the toothing of the arm.
- l’organo di trasmissione può stare naturalmente al centro della corona dentata, semplificando la trasmissione del moto dal motoriduttore (o dal riduttore) alla corona e aumentando la simmetria del treno di ingranaggi (si compensano tolleranze e sforzi), oltre all’equilibrio generale dell’azionamento successivamente fissato a muro o simili; - the transmission element can naturally be in the center of the toothed crown, simplifying the transmission of motion from the gearmotor (or reducer) to the crown and increasing the symmetry of the gear train (tolerances and efforts are compensated), as well as the general balance of the drive subsequently fixed to the wall or the like;
- si può realizzare, secondo le specifiche necessità, un cinematismo epicicloidale a 2, 3 o 4 ingranaggi. Mantenendo inalterate le dimensioni della corona dentata del braccio articolato e dell’albero di uscita del riduttore meccanico, nello spazio dentro la corona dentata si possono inserire almeno 4 ingranaggi uguali. Secondo l’esigenza si ottengono minimo 2 denti in presa (2 ingranaggi), minimo 3 denti in presa (3 ingranaggi) oppure minimo 4 denti in presa (4 ingranaggi); - an epicyclic kinematics with 2, 3 or 4 gears can be created according to specific needs. Keeping the dimensions of the toothed crown of the articulated arm and the output shaft of the mechanical reducer unchanged, at least 4 identical gears can be inserted in the space inside the toothed crown. According to the need, a minimum of 2 meshing teeth (2 gears), a minimum of 3 meshing teeth (3 gears) or a minimum of 4 meshing teeth (4 gears) are obtained;
Qualora l'azionamento comprenda due piastre tra le quali è racchiuso e montato girevole il braccio se ne aumenta la stabilità. If the drive includes two plates between which the arm is enclosed and rotatably mounted, its stability is increased.
Per facilitare il montaggio delle ruote satelliti la piastra più esterna può comprendere sulla superficie rivolta verso il braccio mezzi di imperniamento per gli ingranaggi satelliti, ad es. sedi o fori o perni disposti secondo i vertici di un triangolo equilatero e/o un quadrato. To facilitate the assembly of the planetary wheels, the outermost plate may comprise, on the surface facing the arm, pivoting means for the planetary gears, e.g. seats or holes or pins arranged according to the vertices of an equilateral triangle and / or a square.
I vantaggi e le caratteristiche dell’invenzione saranno maggiormente evidenti dalla seguente descrizione di una forma di realizzazione esemplificativa, con l'allegato disegno in cui: The advantages and characteristics of the invention will be more evident from the following description of an exemplary embodiment, with the attached drawing in which:

Con 10 è indicato un azionamento secondo l’invenzione per un cancello o portone CG. Esso comprende un involucro 12 in cui è contenuto un motore elettrico (non mostrato) il cui albero di uscita è collegato ad un pignone 70 per mezzo di un assieme riduttore 72. Il pignone 70 attraversa una piastra 14, che forma il fondo dell'involucro 12, e trasmette il moto alla dentatura interna 36 presente su un’estremità o sezione anulare cava 34 di un braccio girevole 30 avente un segmento di attuazione 32 snodato con un segmento S collegato al cancello CG. Il braccio 30 è montato girevolmente attorno all’asse verticale X dell’albero di uscita del riduttore 72 (non è necessario sia lo stesso dell’albero di uscita del motore elettrico) tra la piastra 14, superiore, e un’altra piastra inferiore di supporto 50. Le due piastre 14, 50 vanno serrate tra loro in modo noto all’atto del montaggio. 10 indicates a drive according to the invention for a CG gate or door. It comprises a casing 12 which contains an electric motor (not shown) whose output shaft is connected to a pinion 70 by means of a reduction unit 72. The pinion 70 passes through a plate 14, which forms the bottom of the casing 12, and transmits the motion to the internal toothing 36 present on an end or hollow annular section 34 of a rotating arm 30 having an actuation segment 32 articulated with a segment S connected to the gate CG. The arm 30 is rotatably mounted about the vertical axis X of the output shaft of the reducer 72 (it is not necessary to be the same as the output shaft of the electric motor) between the upper plate 14 and another lower plate of support 50. The two plates 14, 50 must be tightened together in a known way at the time of assembly.
L’estremità anulare 34 poggia sulla piastra 50 e contiene nella sua parte inferiore una corona circolare o piedistallo 52 rivolta verso il braccio 30. The annular end 34 rests on the plate 50 and contains in its lower part a circular crown or pedestal 52 facing the arm 30.
Il pignone 70 risulta posizionato al centro della sezione anulare 34 e trasmette moto rotatorio alla dentatura 36 tramite l’impegno su tre uguali mote dentate satelliti 60 che a loro volta ingranano sulla dentatura 36. Le mote 60 sono montate all’interno della sezione anulare 34, disposte secondo i vertici di un triangolo equilatero, e imperniate rotabilmente attorno ad un asse fisso attraverso perni (non mostrati) ancorati a fori 54 ricavati sulla corona circolare 52. The pinion 70 is positioned in the center of the annular section 34 and transmits rotary motion to the toothing 36 by engaging three identical planetary toothed wheels 60 which in turn mesh with the toothing 36. The wheels 60 are mounted inside the annular section 34 , arranged according to the vertices of an equilateral triangle, and rotatably pivoted around a fixed axis by means of pins (not shown) anchored to holes 54 obtained on the circular crown 52.
Si noti che i fori 54 sono sette, e disposti in modo che i perni assiali e le ruote 60 possano essere disposti secondo 3 diverse configurazioni. Su una retta e in posizione opposta (a 180 gradi), secondo i vertici di un triangolo equilatero (a 120 gradi) o secondo i vertici di un quadrato (a 90 gradi), talché si possono utilizzare anche quattro uguali ruote 60, per diverse varianti a maggiore stabilità e potenza. Dalle tre configurazioni si ottengono minimo 2 denti in presa (2 ingranaggi), minimo 3 denti in presa (3 ingranaggi) oppure minimo 4 denti in presa (4 ingranaggi). It should be noted that the holes 54 are seven, and arranged so that the axial pins and the wheels 60 can be arranged according to 3 different configurations. On a straight line and in the opposite position (at 180 degrees), according to the vertices of an equilateral triangle (at 120 degrees) or according to the vertices of a square (at 90 degrees), so that even four equal wheels 60 can be used, for different variants with greater stability and power. From the three configurations, at least 2 meshing teeth (2 gears), at least 3 meshing teeth (3 gears) or at least 4 meshing teeth (4 gears) are obtained.
E’ evidente che quando il pignone 70 ruota, porta in rotazione le mote 60 che a loro volta fanno ruotare il braccio 30. Ora la spinta sulla dentatura 36 viene impressa dai denti di contatto di tutte le mote 60, le quali inoltre ne impediscono il decentramento. It is evident that when the pinion 70 rotates, it causes the wheels 60 to rotate, which in turn cause the arm 30 to rotate. Now the thrust on the toothing 36 is impressed by the contact teeth of all the wheels 60, which also prevent its decentralization.
Si noti che il motore e/o l’involucro 12 potrebbero stare anche sotto il braccio girevole, in una struttura sostanzialmente speculare a quella descritta. Note that the motor and / or the casing 12 could also be under the rotating arm, in a structure substantially mirroring the one described.
In fig. 4 è mostrata una variante dell’invenzione, a dimostrazione di come si possa variare la posizione della dentatura sul braccio girevole. In fig. 4 shows a variant of the invention, demonstrating how the position of the toothing on the rotating arm can be varied.
Un braccio girevole 132 ha stavolta una sezione anulare 134 con una dentatura esterna 136. Due o più ruote satelliti doppie 160 si impegnano con una loro dentatura 161 sulla dentatura 136. Le ruote 160 sono azionate tramite una loro dentatura 163 su un diametro maggiore da un pignone centrale 170 azionato dal motore dell’ azionamento. Le circonferenze di sviluppo delle dentature 161, 163 sono solidali e coassiali. A rotating arm 132 has this time an annular section 134 with an external toothing 136. Two or more double planetary wheels 160 engage with their toothing 161 on the toothing 136. The wheels 160 are driven through their toothing 163 on a larger diameter by a center pinion 170 driven by the drive motor. The development circumferences of the teeth 161, 163 are integral and coaxial.
La coppia sul pignone 170 si scarica sulle dentature 163, che a loro volta fanno girare le dentature 161. Queste agiscono sulla dentatura 136 facendo ruotare il braccio 132. The torque on the pinion 170 is discharged onto the toothings 163, which in turn make the toothings 161 rotate. These act on the toothing 136 by rotating the arm 132.
