Abstract:
The invention relates to adrive machine (1) for an elevator, comprisinga motor module (10) comprising at least a motor (11), a drive shaft (12), and a first transmission wheel (13),which are provided with a common rotational axis and connected coaxially to each other. The drive machine (1) further comprises atraction module(20) comprisingat least a traction wheel (21) engageable with elevator hoisting ropes(40), and a second transmission wheel (22), which are provided with a common rotational axis (X2) and connected coaxially to each other.Themotor module(10) and the traction module(20) are positioned side by side with their rotational axes (X1, X2) parallel, such that the traction wheel (21) and the drive shaft (12) are side by side, and the first and second transmission wheels(13,22) are side by side, and in that the drive machine (1) further comprises an endless drive member (30) passing around the first and second transmission wheels(13, 22).The invention relates also to an elevator comprising said drive machine (1).
Abstract:
An arrangement (200) and a method for changing a direction of movement of an elevator car (10) of an elevator (100), and the elevator thereof, are presented. The arrangement (200) comprises at least two rotatable first stator beam parts (14A) for receiving at least two movers (16) rotatably coupled to the elevator car (10) and at least one actuator (28) for rotating the at least two first stator beam parts (14A). Said stator beam parts (14A) are arranged such that the axes of rotation (25) of said stator beam parts (14A) align with the axes of rotation (26) of the movers (16) when the movers (16) are arranged at corresponding positions. Each one of the movers (16) rotates along with a respective first stator beam part (14A) when said respective first stator beam part (14A) is being rotated by the at least one actuator (28).
Abstract:
An elevator arrangement, comprising an elevator car arranged to move in an elevator shaft or equivalent, preferably along car guide rails, and an element which is disposed in the elevator shaft or equivalent and is shiftable between an activated state and an inactivated state, and an activating device for shifting the said element between the activated and inactivated states. The activating device includes a flexible element, such as e.g. a rope or equivalent, movably attached to a fixed structure of the elevator shaft or equivalent, and the said flexible element is connected to the said shiftable element in a manner permitting the shiftable element to be shifted by means of the flexible element.
Abstract:
Una disposición (200) para cambiar la dirección de movimiento de una cabina de ascensor (10) de un ascensor (100), ascensor (100) que comprende un motor eléctrico lineal para mover la cabina de ascensor (10), caracterizada porque la disposición (200) comprende al menos dos primeras partes de la viga del estator (14A) giratorias que comprenden estatores sin devanado y que están dispuestas en el hueco del ascensor (11) para recibir al menos dos elementos móviles (16), comprendiendo cada uno de los elementos móviles (16) componentes electromagnéticos, tales como un devanado o una bobina, dispuestos para entrar en contacto electromagnético con el estator de la respectiva primera parte de la viga del estator (14A) para mover el elemento móvil a lo largo de la respectiva primera parte de la viga del estator (14A) y estar acoplado de forma giratoria a la cabina del ascensor (10) y al menos un actuador (28) para hacer girar las al menos dos primeras partes de la viga del estator (14A), en el que las al menos dos primeras partes de la viga del estator (14A) giratorias están dispuestas de manera que los ejes de rotación (25) de las primeras partes de la viga del estator (14A) se alinean con los ejes de rotación (26) de los elementos móviles (16) cuando los elementos móviles (16) están dispuestos en posiciones correspondientes con respecto a las al menos dos primeras partes de la viga del estator (14A) para cambiar la dirección de movimiento de la cabina del ascensor (10), en la que cada uno de los elementos móviles (16) gira junto con una respectiva primera parte giratoria de la viga del estator (14A) cuando dicha respectiva primera parte giratoria de la viga del estator (14A) está siendo girada por el al menos un actuador (28).
