Summary: | The invention is referred to a driving system for a lift, which is based on the approximate straight line mechanism, best known as chebyshev mechanism. The lift is driven by being hooked to a series of four arrangements of chebyshev mechanisms along the whole journey. For achieving the aforementioned description, the lift includes four servomotors for rotating their respective axes, which include coupling blades assembled to the coupling link of the chebyshev mechanism, thus making the mid part of the link to be displaced in a vertical line with an approximation very close to the straight line. Once the travel is completed by the chebyshev mechanisms in turn, these transfer the drive shafts, to which the platform of the lift is attached, to the next chebyshev mechanisms. The main characteristic of the invention is that the servomotors never stop rotating in the same direction during its travel through the chebyshev mechanisms until the travel is completed. This technological developme nt removes the machine room upon including the driving shafts for providing the movement power inside the platform, under the cabin.
La invención tiene que ver con el desarrollo de un sistema de propulsión de un elevador basado en el conocido mecanismo de línea recta aproximada, mejor señalado como mecanismo de chebyshev. Para la propulsión del elevador, éste se va enganchando a una serie de cuatro arreglos de mecanismos de chebyshev a lo largo del recorrido. Para lograr esto, el elevador consta de cuatro servomotores que hacen girar sus respectivos ejes, a los cuales se les unen paletas de acoplamiento que se ensamblan al eslabón acoplador del mecanismo de chebyshev, haciendo que la parte media del mencionado eslabón se desplace en una línea vertical con una aproximación muy cercana a la recta. Una vez que los mecanismos de chebyshev en turno han completado su recorrido, éstos transfieren los ejes motores, a los que está unidad la plataforma del elevador, a los siguientes mecanismos de chebyshev. La característica principal es que los servomotores nunca dejan de girar en el mismo sentido en su paso por todos los mecanismos de chebyshev hasta completar el recorrido. Este desarrollo tecnológico elimina el cuarto de máquinas al incluir los motores que proporcionan la energía de movimiento dentro de la plataforma, bajo la cabina. |
