Abstract

The universal torque transformer uses the idea of variable locking to a bearing. In this particular design, the intermediate gears (1), of a gear bearing, whose mission is to transmit or not move the primary shaft (2), the secondary (3), its free rotation is limited by a thyme without-end (4) whose rotation we control externally with a dynamotor. Thus the conversion can oscillate between the transmission of a huge torque at low speed or even zero (clutch) that corresponds to the free rotation and a transmission 1: 1 without reduction that corresponds to the lock, without turning the endless. The most obvious application is the automation sector, solving the problem of slippage of torque converters; its main alternative, and offering a range of enormous transformation that would also enable it for any other mechanical application such as heavy machinery or robotics.

Description

Transformador universal de par motor.Universal torque transformer.

Sector de la técnicaTechnical sector

Se encuadra en el sector de los cambios de marchas de automóviles.It falls within the sector of changes in car gears

Estado de la técnicaState of the art

Actualmente la transformación de régimen y par motor que permita una variación de estos corre a cargo de los cambios de marchas manuales y automáticos de engranajes así como de los variadores continuos de velocidad mediante poleas o convertidores de par hidráulicos.Currently the transformation of regime and torque engine that allows a variation of these is borne by the manual and automatic gear shifts as well as Continuous speed drives by pulleys or hydraulic torque converters.

Problema técnico planteadoTechnical problem raised

La tendencia natural en la evolución de los cambios de marchas es la de ofrecer cada vez más posibilidades de transformación de par y régimen. El poder acometer esta tarea sin que ello suponga un aumento lineal del tamaño y número de piezas del aparato en cuestión resulta fundamental. Paralelamente la mayoría de las máquinas ajenas al mundo de la automoción precisan una gran reducción de régimen de giro con el consiguiente gran aumento de par motor. Un cambio de marchas no se adecua a esa gran reducción, además de resultar demasiado grande y con un excesivo número de piezas de gran complejidad.The natural trend in the evolution of gear changes is to offer more and more possibilities of torque and regime transformation. To be able to undertake this task without that this implies a linear increase in the size and number of pieces of the  The device in question is essential. In parallel, most of the machines outside the automotive world require a great reduction of rotation speed with the consequent large increase in torque A gearshift does not fit that big reduction, in addition to being too large and with an excessive number of pieces of great complexity.

Explicación detalladaDetailed Explanation

El Transformador universal de par motor se basa en la idea de aplicar la estructura de un solo tren epicicloidal o engranaje planetario, y no varios, a la regulación del régimen de giro y par. Así un engranaje planetario en función de los límites que se pongan a su giro libre oscilará entre permitir un elevado régimen de giro en el eje planeta o primario, transmitiendo un escaso o nulo movimiento a la corona o secundario, a transmitir en su totalidad el giro a la corona si se imposibilita el giro libre de los engranajes satélites intermedios. Una de las posibles formas de llevar a cabo ese bloqueo variable consiste en la realización de un tren epicicloidal. La tendencia natural al giro libre de los engranajes satélites en tomo a su propio eje cuando gira el engranaje planeta o primario se vera limitado por un tornillo sin-fin engranado a estos. A su vez el sin-fin es abrazado por una pieza solidaria a los ejes de los engranajes satélites, de forma que el sin-fin permanece firmemente engranado a los satélites, por lo que el tren de satélites y los tornillos sin-fin giran engranados y en bloque en tomo al eje planeta sujetos por dicha pieza. Tanto los brazos de la pieza que rodea el sin-fin como los ejes de los engranajes satélites tienen en su interior bolas de rodamiento que permiten el giro en tomo a su propio eje de planeta y sin fin fuertemente engranados. La parte mas externa del sin-fin está fresada como una rueda dentada con dientes rectos longitudinales, estos engranan con una pieza circular en forma de arandela plana fresada con dientes rectos radiales en una de sus caras. El efecto de este engranaje es tal, que cuando el engranaje en forma de arandela está en reposo y el bloque de satélites, tornillos sin-fin y pieza que los une gira forzado por el giro del eje motor planeta, la arandela provoca un giro de los sin-fin a revoluciones suficientes como para igualar en los satélites el régimen de giro del engranaje planeta o primario pero en sentido contrario, lo que significa en la practica permitir el giro libre de los engranajes satélites intermedios; equivalente a posición "embragado" de un cambio de marchas convencional. Si aceleramos el engranaje en forma de arandela mediante un motor eléctrico de control iremos reduciendo progresivamente las revoluciones del sin-fin en tomo a su propio eje. Al irnos acercando al régimen de giro del bloque sin-fin unido a satélites, se irá limitando el giro libre de los engranajes satélites intermedios, transmitiéndose cada vez mas régimen de giro del planeta a la corona, cuando las revoluciones del engranaje en forma de arandela igualen el régimen de giro del eje motor planeta; la arandela y el bloque sin-fin/satélites irán a la misma velocidad, el sin-fin permanecerá quieto en tomo a su propio eje, por lo que los engranajes satélites intermedios también lo estarán y el conjunto girará en bloque transmitiendo así completamente el giro del engranaje planetario primario a la corona o secundario sin reducción alguna, el equivalente a la posición "directa" en un cambio de marchas convencional. Hay que destacar que este proceso se realizará a favor de resistencia, puesto que la tendencia natural del sin-fin en esta disposición es a permanecer quieto, si no se le obliga a girar mediante la pieza en forma de arandela.The universal torque transformer is based in the idea of applying the structure of a single epicycloidal train or planetary gear, and not several, to the regulation of the regime of twist and torque Thus a planetary gear depending on the limits that are put to your free spin will oscillate between allowing a high rotation regime on the planet or primary axis, transmitting a little or no movement to the crown or secondary, to be transmitted in the full turn to the crown if free spin is disabled of intermediate satellite gears. One of the possible ways of carrying out that variable block consists in the realization of an epicyclic train The natural tendency to free spin of gears satellites on its own axis when the planet or primary gear will be limited by a screw Endless geared to these. Turn the Endless is embraced by a piece in solidarity with the axes of the satellite gears, so that the Endless remains firmly engaged in satellites, so the satellite train and screws Endless rotate geared and in block on the shaft planet subject by said piece. Both the arms of the piece that surround the endless like the axes of the gears satellites have inside bearing balls that allow the turn in volume to its own planet axis and endlessly strongly geared The outermost part of the endless is milled like a cogwheel with straight longitudinal teeth, these mesh with a circular piece in the form of a flat washer Milling with radial straight teeth on one of its faces. The effect of this gear is such that when the gear in the form of washer is at rest and the satellite block, screws endless and piece that unites them tour forced by the rotation of the planet motor axis, the washer causes a rotation of the endless at enough revolutions to equalize on the satellites the rotation regime of the planet gear or primary but in the opposite direction, what it means in practice allow free rotation of intermediate satellite gears; equivalent to "clutch" position of a gearshift conventional. If we accelerate the washer-shaped gear by means of an electric motor of control we will reduce progressively the endless revolutions in tome to its own axis. As we approach the rotation regime of the block Endlessly attached to satellites, the turn will be limited free of intermediate satellite gears, transmitting every more and more regime of rotation of the planet to the crown, when washer-shaped gear revolutions match the speed of rotation of the planet motor axis; the washer and the block Endless / satellites will go at the same speed, the Endless will remain still on its own axis, so the intermediate satellite gears will be too and the set will turn in block thus transmitting completely the rotation of the primary planetary gear to the crown or secondary without any reduction, the equivalent to the "direct" position in a conventional gearshift. It should be noted that this process will be carried out in favor of resistance, since the trend natural of the endless in this provision is to remain still, if you are not forced to turn by the piece in washer shape.

Descripción de las figurasDescription of the figures

Figura 1 el eje motor es solidario a un engranaje planeta o primario (1) que transmite su movimiento a un engranaje corona o secundario (2) concéntrico a este, a través de unos engranajes satélites intermedios (3) cuyos ejes tienen rodamientos de bolas (4). El giro libre de estos en torno a su propio eje está limitado por un tornillo sin-fin (5) con dos rodamientos de bolas en el centro (6) cuya parte más externa esta frenada como un engranaje con dientes rectos longitudinales (7). Figura 2 los satélites (3) sobresalen un poco para permitir la unión con el sin-fin sin que roce la corona. Figura 3 los dientes rectos del extremo del sin-fin engranan con un pieza en forma de arandela (8). Los tornillos sin-fin se sujetan firmemente a los satélites mediante una pieza que los abraza (9) en la zona de los dos rodamientos de bolas circulares (16). A su vez, esta pieza está soldada a los tres ejes (4) con rodamientos de los engranajes intermedios con lo que la pieza los satélites y tornillos sin-fin forman un solo bloque. Figura 4 detalle de la parte mas externa del engranaje en forma de arandela (8) cuyo giro controlamos externamente mediante un motor eléctrico que engrana por rueda dentada (10) solo en la parte externa de la arandela de forma que no roce con (7) que engrana en la parte interna, según aceleremos la arandela para igualar con el régimen de giro del planeta se ira frenando el giro de los sin-fin con lo que los planetas se bloquearán progresivamente hasta quedar quietos en torno a su propio eje, obligando a la corona a girar a las mismas revoluciones que el planeta.Figure 1 the drive shaft is integral to a planet or primary gear (1) that transmits its movement to a crown or secondary gear (2) concentric to this, through intermediate satellite gears (3) whose axes have ball bearings (4). The free spin of these around their own shaft is limited by an endless screw (5) with two ball bearings in the center (6) whose most part external is braked like a gear with straight teeth Longitudinal (7). Figure 2 satellites (3) stand out a bit to allow union with the endless without rubbing the crown. Figure 3 straight teeth at the end of the Endless gear with a washer-shaped piece (8). End screws are firmly attached to the satellites by means of a piece that hugs them (9) in the zone of the two circular ball bearings (16). In turn, this piece It is welded to all three shafts (4) with gear bearings intermediate so the piece satellites and screws Endless form a single block. Figure 4 detail of the outermost part of the washer-shaped gear (8) whose turn we control externally by an electric motor that gear by cogwheel (10) only on the outside of the washer so that it does not rub with (7) that engages in the part internal, as we accelerate the washer to match the regime Turn of the planet will slow the turn of the endless with what the planets will block progressively until they stand still around their own axis, forcing the crown to turn at the same revolutions as the planet.

Modo de realizaciónEmbodiment

Las piezas son: Un engranaje planeta que se unirá a la fuente motriz tallado con dientes oblicuos; tres planetas también tallados con dientes oblicuos de forma que ajusten con; los dientes espirales de tres tornillos sin-fin con una parte central con nichos para rodamientos de bolas y una parte externa fresada con dientes rectos longitudinales; una pieza que abraza a los sin-fin por su parte central con rodamientos de bolas y se suelda a los tres ejes con rodamientos de los satélites; una pieza en forma de arandela fresada en una cara con dientes radiales. En este ejemplo concreto el engranaje motor central planeta esta girando y transmitiendo su giro a los tres engranajes satélites, estos forman un solo bloque que gira unido con los tres tornillos sin-fin y la pieza de forma triangular con brazos en los vértices que une los sin-fin con los ejes de los satélites. Pese a que la pieza permite el giro entorno a sus propios ejes de planetas y sin-fin, la tendencia natural de esta disposición es que el planeta esté bloqueado transmitiendo la totalidad del giro a la corona rotando así en bloque todas las piezas del diseño, pues un planeta no puede forzar a girar a sin-fin, mientras que este al planeta, sí. No obstante si controlamos externamente el giro de un engranaje en forma de arandela con dientes radiales que ajusta convenientemente con los dientes longitudinales fresados en la parte más externa de los tres tornillos sin-fin podremos sin esfuerzo controlar el giro de los sin-fin que a su vez permitirán progresivamente el desbloqueo de los tres satélites. Conforme los tres satélites se desbloquean van girando en torno a su propio eje, pero en sentido contrario al giro del planeta motor central. El bloque 3satélites-3sin-fin y pieza que los une gira en mismo sentido que el planeta, pero cada vez lo hace más lentamente, pues estamos permitiendo cada vez más giro en torno a su propio eje de los tres satélites al forzar el giro del sin-fin. Cuantas más revoluciones gire el sin-fin mas giro libre en sentido contrario permitirá a los planetas, más lentamente girará el bloque 3planetas- 3sin-fin y pieza que los une, transmitiendo menos revoluciones a la corona aunque con mayor par motor. El conjunto de piezas es abundantemente lubricado a presión pues el engranaje sin-fin/satélite presenta elevado rozamiento.The pieces are: A planet gear that join the carved motor source with oblique teeth; three planets also carved with oblique teeth so that they fit with; three screw spiral teeth Endless with a central part with niches for ball bearings and a milled outer part with straight teeth longitudinal; a piece that embraces the endless by its central part with ball bearings and welded to three axes with satellite bearings; a piece in the form of milled washer on one side with radial teeth. In this example concrete the planet central motor gear is spinning and transmitting its turn to the three satellite gears, these form a single rotating block attached with the three screws Endless and triangular shaped piece with arms in the vertices that unites the endless with the axes of The satellites Although the piece allows the rotation around its own axes of planets and endless, the trend natural of this provision is that the planet is locked transmitting the entire turn to the crown thus rotating in block all the pieces of the design, because a planet cannot force to turn to endless, while on the planet, yes. However, if we externally control the rotation of a gear in Radial teeth washer shape that fits conveniently with longitudinal teeth milled on the outermost part of the three endless screws we can effortlessly control the spin of the endless ones which in turn will allow progressively the unlocking of the three satellites. As the three satellites are unlocked they revolve around their own axis, but in the opposite direction to the rotation of the motor planet central. The block 3satélites-3sin-fin and piece that un tour in the same direction as the planet, but every time it does more slowly, because we are allowing more and more turn around its own axis of the three satellites by forcing the rotation of the endless. The more revolutions the Endless plus free spin in the opposite direction will allow the planets, more slowly the 3 planets block will rotate- 3sin-end and piece that unites them, transmitting less crown revolutions although with greater torque. The set of pieces are abundantly pressure lubricated as the gear Endless / satellite has high friction.
