Description

Polea dentada perfeccionada.Improved toothed pulley.

Technical field

La presente invención se refiere a una polea dentada del tipo empleado preferentemente en sistemas de transporte y transmisión por correas.The present invention relates to a pulley teeth of the type preferably used in transport systems and belt drive.

Background of the invention

Convencionalmente las poleas dentadas consisten en una rueda dotada de una pluralidad de dientes en su periferia, que gira sobre un eje y sobre la que engrana una correa dentada cuya misión puede ser la de transmisión de movimiento hacia otra polea o bien la de transporte de objetos en función general de cinta transportadora.Conventionally the toothed pulleys consist in a wheel endowed with a plurality of teeth on its periphery, which rotates on an axis and on which a toothed belt meshes whose mission may be to transmit movement to another pulley or the transport of objects in general function of conveyer belt.

En cualquier caso, es necesario dotar a estos sistemas mecánicos de medios para el guiado y centrado correcto de la correa sobre la polea. Para ello, la rueda suele estar acanalada, presentando dos valonas perimetrales en sus costados, entre las cuales queda alojada la correa sin posibilidad de salirse de la polea en su acción de giro.In any case, it is necessary to provide these mechanical media systems for correct guidance and centering of the belt on the pulley. To do this, the wheel is usually corrugated, presenting two perimeter walloons on its sides, between which the belt is housed without the possibility of getting out of the pulley in its turning action.

Esta solución es apropiada cuando las correas se utilizan como elemento de transmisión de movimiento, sin embargo presentan inconvenientes cuando la correa se emplea como cinta de transporte. Concretamente, en estos casos existe la posibilidad de que las valonas marquen el material transportado por la cinta, sobre todo si se trata de material fácilmente deformable y pesado, como por ejemplo bloques de revistas.This solution is appropriate when the straps are use as a motion transmission element, however they have problems when the belt is used as a belt transport. Specifically, in these cases there is the possibility of that the walls mark the material transported by the belt, especially if it is easily deformable and heavy material, such as magazine blocks.

Description of the invention

En términos generales, la presente invención se refiere a una polea dentada perfeccionada cuyo diseño facilita el autocentrado de la correa sin la necesidad de valonas ni otros medios de centrado externos. Por ello resulta ideal en aplicaciones de cinta de transporte.Generally speaking, the present invention will be refers to an improved toothed pulley whose design facilitates the self-centering of the belt without the need for walloons or others external centering means. Therefore it is ideal in applications of transport belt.

En concreto, la nueva polea dentada presenta, en la superficie de los dientes de tracción previstos en su periferia, una pluralidad de ranuras dispuestas preferiblemente de forma perpendicular a los dientes, siendo su profundidad inferior a la altura de estos y destinadas a autocentrar la correa a la que se asocia, para lo cual dicha correa presentará una huella concordante con las características de la polea.Specifically, the new toothed pulley presents, in the surface of the traction teeth provided on its periphery, a plurality of grooves preferably arranged perpendicular to the teeth, its depth being less than height of these and intended to self-center the belt at which associate, for which said belt will present a concordant footprint With the characteristics of the pulley.

Estas ranuras presentes en los dientes de tracción presentan preferiblemente sección triangular, y pueden ser realizadas fácilmente mediante cualquier técnica de fresado.These grooves present in the teeth of traction preferably have triangular section, and can be easily made by any milling technique.

Description of the drawings

Con el objeto de ilustrar cuanto hasta ahora hemos expuesto, se acompaña a la presente memoria descriptiva de una hoja de dibujos en la que se ha representado de manera simplificada y esquemática un ejemplo de realización únicamente ilustrativo y no limitativo de las posibilidades practicas de la invención.In order to illustrate how much so far we have exposed, is accompanied by the present specification of a sheet of drawings on which it has been represented so simplified and schematic an embodiment only illustrative and not limiting the practical possibilities of the invention.

En dicho dibujo, la figura 1 representa una vista en perspectiva de la novedosa polea.In said drawing, figure 1 represents a Perspective view of the novel pulley.

Example Description

Según el dibujo, la nueva polea dentada presenta, en la superficie de los dientes de tracción (1) previstos en su periferia, una pluralidad de ranuras de sección triangular (2) dispuestas preferiblemente de forma perpendicular a los dientes (1), siendo su profundidad inferior a la altura de estos.According to the drawing, the new toothed pulley presents, on the surface of the traction teeth (1) provided on its periphery, a plurality of triangular grooves (2) preferably arranged perpendicular to the teeth (1), their depth being less than their height.

Serán independientes del objeto de la presente invención los materiales que se empleen en la fabricación de los distintos elementos que la componen, así como las formas, dimensiones y accesorios que pueda presentar, pudiendo ser reemplazados por otros técnicamente equivalentes, siempre que no afecten a la esencialidad de la misma ni se aparten del ámbito definido en el apartado de reivindicaciones.They will be independent of the purpose of this invention the materials used in the manufacture of different elements that compose it, as well as the forms, dimensions and accessories that may present, and may be replaced by other technically equivalent ones, provided that no affect the essentiality of it or depart from the scope defined in the claims section.

Establecido el concepto expresado, se redacta a continuación la nota de reivindicaciones, sintetizando así las novedades que se desean reivindicar.Established the expressed concept, it is written to then the note of claims, thus synthesizing the news that you want to claim.
