Description

Ventilador de motor de rotor exterior.External rotor motor fan.

La presente solicitud de Modelo de Utilidad se refiere a un ventilador de motor de rotor exterior cuyas nuevas características proporcionan numerosas ventajas, tal como se detallará en la presente memoria.The present Utility Model application is refers to an external rotor motor fan whose new features provide numerous advantages, as is will detail herein.

El ventilador de motor de rotor exterior de la presente invención comprende esencialmente una hélice o rodete que está formado por un núcleo o rotor-cubo dotado de una serie de palas y un eje solidario de dicho rotor-cubo. Las palas están constituidas por elementos independientes que se montan de manera individual en el rotor-cubo y distribuidas radialmente en el mismo. El acoplamiento individual de las palas en el rotor-cubo permite la regulación angular de las mismas para realizar una regulación precisa del ventilador según los requerimientos de la instalación, permitiendo llevar a cabo esta adaptación incluso en instalaciones ya en uso. Esta regulación angular de las palas puede llevarse a cabo sin tener que desmontar la hélice del eje.The outer rotor motor fan of the The present invention essentially comprises a propeller or impeller that It is formed by a core or rotor-hub equipped with a series of blades and a supportive axis of said rotor-hub. The blades are constituted by independent elements that are mounted individually in the rotor-hub and radially distributed therein. The individual coupling of the blades in the rotor-hub allows angular regulation of same to make a precise regulation of the fan according to installation requirements, allowing to carry out this adaptation even in facilities already in use. This regulation Angular blades can be carried out without having to disassemble The propeller shaft.

Las palas del ventilador de la presente invención se disponen en el rotor-cubo de una manera que no pueden desprenderse del mismo de manera fortuita, quedando sujetas al mismo de manera segura y, al mismo tiempo, regulable, tal como se detallará en lo sucesivo.The fan blades of the present invention  they are arranged in the rotor-hub in a way that does not can be accidentally detached from it, being subject at the same time in a safe and, at the same time, adjustable way, as will detail in the following.

En particular, se dispone, de acuerdo con la invención, un ventilador de motor de rotor exterior incorpora un rotor-cubo central, es decir, un rotor de motor que hace las funciones de cubo. Este rotor-cubo incluye un cuerpo, solidario del mismo, el cual es susceptible de acoplarse a un elemento de cierre formado por un cuerpo complementario. El cuerpo solidario del rotor-cubo y el cuerpo complementario presentan ambos unas aberturas o entradas semicirculares que definen correspondientes aberturas para acoplar una pluralidad de palas.In particular, it is arranged in accordance with the invention, an external rotor motor fan incorporates a central rotor-hub, that is, a motor rotor that It does the cube functions. This rotor-hub includes a body, supportive of it, which is capable of coupling to a closure element formed by a complementary body. The solidarity body of the rotor-hub and the body complementary both have openings or entrances semicirculars that define corresponding openings for coupling a plurality of blades.

Las palas del ventilador de la presente invención presentan una zona de pala y una zona de acoplamiento opuesta. Esta zona de acoplamiento presenta una forma substancialmente cilíndrica de escasa altura destinada a insertarse en cada abertura formada en el rotor-cubo, y una ranura periférica que ajusta en un reasalte circunferencial formado en cada abertura semicircular de los cuerpos. Esta configuración estructural permite ventajosamente que cada pala quede acoplada en el rotor-cubo de manera desmontable y regulable angularmente, sin posibilidad de desprenderse del rotor-cubo una vez montado el mismo.The fan blades of the present invention they have a shovel area and an opposite coupling area. Is coupling area has a substantially cylindrical shape low height intended to be inserted in each opening formed in the rotor-hub, and a peripheral groove that adjusts in a circumferential highlight formed at each opening semicircular of the bodies. This structural configuration allows advantageously that each blade is coupled in the rotor-hub removable and adjustable angularly, without the possibility of detaching from rotor-hub once mounted.

Para ello, el cuerpo solidario del rotor-cubo y el cuerpo complementario presentan unos orificios longitudinales situados entre cada dos aberturas adyacentes en los cuales se alojan unos tornillos para fijar los cuerpos e inmovilizar entre ellos la zona de acoplamiento de cada pala.For this, the solidarity body of rotor-hub and complementary body present longitudinal holes located between each two openings adjacent in which some screws are housed to fix the bodies and immobilize between them the coupling area of each shovel.

Se obtiene así un ventilador de motor de rotor exterior de una gran versatilidad ya que la variación de la inclinación de las palas se convierte en una operación muy sencilla y rápida. Además, las palas quedan retenidas en el rotor de una manera notablemente segura, sin que exista riesgo alguno de que éstas puedan salirse del mismo. Otra ventaja de la invención es que en un mismo rodete es posible montar palas de características muy distintas, de manera que con una configuración de rotor universal se obtienen ventiladores de comportamiento distinto de manera que se puede adaptar a requerimientos distintos con un coste reducido.A rotor motor fan is thus obtained exterior of great versatility since the variation of the tilt of the blades becomes a very simple operation and fast. In addition, the blades are retained in the rotor of a remarkably safe way, without any risk of They can get out of it. Another advantage of the invention is that in the same impeller it is possible to mount shovels of characteristics very different, so that with a universal rotor configuration different behavior fans are obtained so that It can be adapted to different requirements at a cost reduced.
