DESCRIZIONE dell?invenzione avente per titolo: DESCRIPTION of the invention entitled:
?Meccanismo per avere in uscita un albero rotante in un sol senso quando l?albero in entrata ruota in un senso e nel senso opposto.? ?Mechanism for having an output shaft rotating in one direction only when the input shaft rotates in one direction and in the opposite direction.?
Il presente trovato per poter disporre di un Meccanismo semplice ed affidabile per avere la rotazione di un albero in uscita in un sol senso a prescindere dal senso di rotazione dell?albero in entrata. The present invention is to provide a simple and reliable mechanism for rotating an output shaft in one direction only, regardless of the direction of rotation of the input shaft.
SETTORE TECNICO TECHNICAL FIELD
Trasmissione del moto rotatorio Transmission of rotary motion
Si noti che: Please note that:
- Il presente trovato non ? di semplice intuizione neppure per un tecnico del ramo; - The present found is not? simple intuition even for a technician in the field;
- due alberi ruotano in senso opposto l?uno all?altro quando si trasmettono il moto rotatorio per contatto diretto mediante due pulegge fisse dentate; due alberi ruotano nello stesso senso quando si trasmettono il moto rotatorio indirettamente mediante un organo di trasmissione flessibile quale cinghia o catena. - two shafts rotate in the opposite direction to each other when the rotary motion is transmitted by direct contact via two fixed toothed pulleys; two shafts rotate in the same direction when they transmit rotary motion indirectly via a flexible transmission member such as a belt or chain.
Nel prosieguo viene definita ruota libera una puleggia costituita di un mozzo centrale solidale al suo albero, di una corona esterna e di un congegno a ruota libera interposto fra il mozzo e la corona esterna. Detto congegno quando l?albero ruota in un dato senso costringe la corona esterna a divenire solidale al mozzo e quindi entrambi, ruota libera con la sua corona esterna e mozzo col suo albero, ruotano nello stesso senso; quando l?albero ruota in senso contrario a detto dato senso toglie tale vincolo fra i due, corona esterna e mozzo, che sono liberi di ruotare uno in senso contrario all?altro. In the following, a freewheel is defined as a pulley made up of a central hub integral with its shaft, an external crown and a freewheel device placed between the hub and the external crown. Said device, when the shaft rotates in a given direction, forces the external crown to become integral with the hub and therefore both, the free wheel with its external crown and the hub with its shaft, rotate in the same direction; when the shaft rotates in the opposite direction to said direction it removes this bond between the two, external crown and hub, which are free to rotate in the opposite direction to the other.
MECCANISMO OGGETTO DEL PRESENTE TROVATO MECHANISM SUBJECT OF THIS FINDING
Il Meccanismo ? sostanzialmente composto di un albero in entrata, che in fase operativa riceve il moto rotatorio dall?esterno in un senso e nel senso opposto, di un albero intermedio che riceve il moto rotatorio dall?albero in entrata direttamente mediante due pulegge fisse dentate ad essi solidali e quindi ruota sempre in senso contrario all?albero in entrata e di un albero in uscita che ruota solo in un dato senso. L?albero in entrata trasmette il suo moto rotatorio all?albero intermedio anche indirettamente mediante un organo di trasmissione flessibile e le corone sterne di due ruote libere, una per ogni singolo albero poste nel verso che si rendono solidali ai rispettivi alberi quando questi ruotano entrambi in un determinato senso e di conseguenza, qualunque sia il senso di rotazione di detto albero in entrata, la corona esterna di una delle due ruote libere ruota in senso contrario al suo albero mentre l?altra corona esterna dell?altra ruota libera risulta solidale al suo albero. Detto organo di trasmissione flessibile trasmette il moto rotatorio di una delle due corone di dette ruote libere anche ad una terza puleggia fissa, solidale all?albero in uscita che ruota sempre in un solo e determinato senso. The Mechanism? substantially composed of an input shaft, which in the operating phase receives the rotary motion from the outside in one direction and in the opposite direction, of an intermediate shaft which receives the rotary motion from the input shaft directly via two fixed toothed pulleys integral with them and therefore always rotates in the opposite direction to the input shaft and of an output shaft that rotates only in a given direction. The input shaft transmits its rotary motion to the intermediate shaft also indirectly through a flexible transmission member and the external crowns of two free wheels, one for each individual shaft placed in the direction which becomes integral with the respective shafts when they both rotate in a given direction and consequently, whatever the direction of rotation of said input shaft, the external crown of one of the two free wheels rotates in the opposite direction to its shaft while the other external crown of the other free wheel is integral with the his tree. Said flexible transmission member also transmits the rotary motion of one of the two crowns of said free wheels to a third fixed pulley, integral with the output shaft which always rotates in a single and specific direction.
FUNZIONAMENTO DEL MECCANISMO OPERATION OF THE MECHANISM
Al fine di semplificare la descrizione presupponiamo che: In order to simplify the description we assume that:
- Il Meccanismo sia visto da un osservatore posto dalla parte dove all?albero in entrata arriva il moto rotatorio dal l?esterno; - The Mechanism is seen by an observer placed on the side where the rotary motion reaches the input shaft from the outside;
- L?organo di trasmissione flessibile sia una catena preferenzialmente del tipo Galle; - The flexible transmission component is preferably a Galle type chain;
- Le corone esterne delle due ruote libere e della puleggia fissa solidale all?albero in uscita siano dentate ed atte ad accoppiarsi con detta catena; - The external crowns of the two free wheels and of the fixed pulley integral with the output shaft are toothed and suitable for coupling with said chain;
- Le due ruote ibere sono poste nello stesso verso e si rendono solidali ai rispettivi alberi quando detti alberi ruotano in senso orario. - The two freewheels are placed in the same direction and become integral with the respective shafts when said shafts rotate clockwise.
Rotazione in senso orario dell?albero in entrata Clockwise rotation of the input shaft
Quando l?albero in entrata ruota in senso orario la corona della sua ruota libera ? ad esso solidale; detta ruota libera quindi trasmette il moto rotatorio in senso orario dell?albero in entrata, indirettamente mediante la catena, alla puleggia fissa solidale all?albero in uscita che di conseguenza ruota in senso orario. La corona esterna della ruota libera dell?albero intermedio ruota in senso contrario al suo albero perch?, non girando detto albero in senso orario, non gli ? solidale e quindi non trasmette il moto rotatorio del suo albero. When the input shaft rotates clockwise the crown of its free wheel? in solidarity with it; said free wheel then transmits the clockwise rotary motion of the input shaft, indirectly via the chain, to the fixed pulley integral with the output shaft which consequently rotates clockwise. The external crown of the freewheel of the intermediate shaft rotates in the opposite direction to its shaft because, by not turning said shaft clockwise, it is not suitable for it? integral and therefore does not transmit the rotary motion of its shaft.
Rotazione in senso antiorario dell?albero in entrata Counterclockwise rotation of the input shaft
Quando l?albero in entrata ruota in senso antiorario la sua ruota libera non gli ? solidale e ruota in senso contrario al suo albero e quindi detto albero in entrata non trasmette il suo moto rotatorio; l?albero When the input shaft rotates counterclockwise, its freewheel is not working. integral with and rotates in the opposite direction to its shaft and therefore said input shaft does not transmit its rotary motion; the tree
intermedio ruota in senso orario con la sua ruota libera ad esso solidale che trasmette il moto rotatorio in intermediate wheel rotates clockwise with its free wheel integral with it which transmits the rotary motion in
senso orario di detto albero intermedio, indirettamente mediante la catena, alla puleggia fissa solidale clockwise direction of said intermediate shaft, indirectly via the chain, to the fixed pulley integral with it
all?albero in uscita che di conseguenza ruota in senso orario. to the output shaft which consequently rotates clockwise.
In definitiva per quanto presupposto sopra l?albero in uscita ruota sempre in senso orario qualunque sia il Ultimately, as per the above assumptions, the output shaft always rotates clockwise whatever the
senso di rotazione dell?albero in entrata. direction of rotation of the input shaft.
Tali ed altre caratteristiche del Meccanismo oggetto del presente trovato appariranno evidenti dalla These and other characteristics of the Mechanism object of the present invention will appear evident from
seguente descrizione, fatta a titolo d?esempio non limitativo di un esemplare del Meccanismo stesso, con following description, made as a non-limiting example of an example of the Mechanism itself, with
riferimento alle figure del disegno allegato in cui; reference to the figures in the attached drawing in which;
La Figura 1) ? una vista del Meccanismo da parte di un osservatore che si pone obliquamente dalla parte dell?Albero in Uscita. Figure 1) ? a view of the Mechanism from an observer who stands obliquely on the side of the Output Shaft.
La Figura 2) ? una vista del Meccanismo da parte di un osservatore che si pone dalla parte dell?Albero in Uscita ortogonalmente alle pulegge fisse dentate. Figure 2) ? a view of the Mechanism from an observer who stands on the side of the Output Shaft orthogonally to the toothed fixed pulleys.
Con riferimento alle figure della tavola di disegno allegata con (t) viene indicato l?Albero in Entrata che in fase operativa riceve il moto rotatorio dall?esterno in un senso e nel senso opposto, con (2) l?Albero Intermedio che ruota sempre in senso opposto a detto Albero in Entrata e con (3) l?Albero in Uscita che ruota solo in un dato senso. L?Albero in Entrata (1) e l?Albero Intermedio (2) si trasmettono il moto rotatorio sia direttamente mediante due pulegge f?sse dentate una (11) solidale a detto Albero in Entrata e una (21) solidale a detto Albero Intermedio, sia indirettamente mediante la Catena (4) e due ruote libere, una (12) operativamente vincolata a detto Albero in Entrata ed una (22) operativamente vincolata a detto Albero Intermedio, poste nel verso da rendersi solidali ai rispettivi alberi quando questi ruotano entrambi in un determinato senso. La Catena (4) trasmette il moto rotatorio della corona di una delle due ruote libere, mentre l?altra ruota folle, alla Puleggia Fissa (31) solidale a detto Albero in Uscita. With reference to the figures in the attached drawing table, (t) indicates the Input Shaft which in the operating phase receives rotary motion from the outside in one direction and in the opposite direction, with (2) the Intermediate Shaft which always rotates in the opposite direction to said Input Shaft and with (3) the Output Shaft rotating only in a given direction. The Input Shaft (1) and the Intermediate Shaft (2) transmit rotary motion directly via two fixed toothed pulleys, one (11) integral with said Input Shaft and one (21) integral with said Intermediate Shaft, both indirectly through the Chain (4) and two free wheels, one (12) operationally linked to said Input Shaft and one (22) operationally linked to said Intermediate Shaft, placed in the direction to become integral with the respective shafts when these both rotate in a certain meaning. The Chain (4) transmits the rotary motion of the crown of one of the two free wheels, while the other rotates idle, to the Fixed Pulley (31) integral with said Output Shaft.
Se ci poniamo dalla parte dove all?Albero in Entrata (I) arriva il moto rotatorio dall?esterno e stabiliamo di posizionare le ruote libere nel verso che le toro corone si rendono solidali ai rispettivi alberi quando questi ruotano in senso orario, quando l?Albero in Entrata (1) ruota in senso orario diventa solidale con la corona della sua Ruota Libera (12) che trasmette il moto rotatorio in senso orario dell?Albero in Entrata, indirettamente mediante la Catena (4), alla Puleggia Fissa (31) solidale all?Albero in Uscita (3) che di conseguenza ruota in senso orario. La corona della Ruota Libera (22) ruota in senso contrario all?Albero Intermedio (2) perch? non girando detto albero in senso orario non gli ? solidale. If we place ourselves on the side where the rotary motion arrives from the outside to the Input Shaft (I) and we decide to position the free wheels in the direction that the torus crowns become integral with the respective shafts when they rotate clockwise, when the Input Shaft (1) rotates clockwise and becomes integral with the crown of its Freewheel (12) which transmits the clockwise rotary motion of the Input Shaft, indirectly through the Chain (4), to the Fixed Pulley (31) integral with the Output Shaft (3) which consequently rotates clockwise. The crown of the Freewheel (22) rotates in the opposite direction to the Intermediate Shaft (2) because? by not turning said tree clockwise the ? supportive.
Per come stabilito sopra, quando l?Albero in Entrata (1) ruota in senso antiorario non diventa solidale con la corona della sua Ruota Libera (12) che quindi ruota in senso contrario al medesimo albero, mentre l?Albero intermedio (2), che ruota in senso orario, viene reso solidale alla corona della sua Ruota Libera (22) che quindi trasmette il suo moto rotatorio in senso orario, indirettamente mediante la Catena (4), alla Puleggia Fissa (31) solidale all?Albero in Uscita (3) che di conseguenza ruota in senso orario. As established above, when the Input Shaft (1) rotates counterclockwise it does not become integral with the crown of its Freewheel (12) which therefore rotates in the opposite direction to the same shaft, while the Intermediate Shaft (2), which rotates clockwise, is made integral with the crown of its Free Wheel (22) which then transmits its rotary motion clockwise, indirectly through the Chain (4), to the Fixed Pulley (31) integral with the Output Shaft ( 3) which consequently rotates clockwise.
Quindi per quanto stabilito sopra detto, in sede operativa l?Albero in Uscita ruota sempre in senso orario qualunque sia il senso di rotazione dell?Albero in Entrata Therefore, as established above, in operation the Output Shaft always rotates clockwise regardless of the direction of rotation of the Input Shaft
