Abstract

Assembly method of a pulley. The present invention relates to a method of mounting a pulley on a drum shaft, comprising the following steps: providing a drum whose shaft has in an end zone a coupling region with a geometry that does not correspond to a surface of revolution, provide a pulley that has a protruding hub, introduce the coupling region of the shaft in the hub of the pulley, and deform the hub of the pulley by pressing against the drum axis to adapt the hub to the geometry of the region of coupling (Machine-translation by Google Translate, not legally binding)

revolución engendrada alrededor del eje imaginario del tambor 6. Esto es debido, en esta realización, a que la región de acoplamiento 4 presenta una pluralidad de hendiduras 5 dispuestas en paralelo al eje imaginario del tambor 6. revolution generated around the imaginary axis of the drum 6. This is due, in this embodiment, to the coupling region 4 having a plurality of grooves 5 arranged parallel to the imaginary axis of the drum 6.

d. deformar el cubo de la polea por presión contra el eje 1 del tambor para adaptar el cubo 3 a la geometría de la región de acoplamiento 4. d. deform the pulley hub by pressure against the axis 1 of the drum to adapt the hub 3 to the geometry of the coupling region 4.

En el ejemplo de realización mostrado en la figura 2, se muestra esquemáticamente la etapa d) del método de acuerdo a la presente invención. En esta etapa el extremo del eje 1 del tambor que presenta la región de acoplamiento 4 está introducido en el cubo 3 sobresaliente de la polea 2 y el cubo sobresaliente 3 de la polea se deforma 7 por presión sobre la región de acoplamiento 4 del eje del tambor, por ejemplo a través de una herramienta hidráulica 8. Esta deformación 7 produce una unión ajustada entre el eje 1 del tambor y la polea 2. Gracias a la forma y a la posición de las hendiduras 5 previstas en la región de acoplamiento 4 del eje 1 del tambor, el acoplamiento entre la polea 2 y eje 1 del tambor permite el arrastre del eje 1 del tambor como resultado del giro de la polea 2. Gracias a la geometría de la región de acoplamiento 4 del eje 1 del tambor, la unión resultante no comprende elementos móviles, resolviendo los problemas del estado de la técnica. In the exemplary embodiment shown in Figure 2, step d) of the method according to the present invention is schematically shown. At this stage the end of the shaft 1 of the drum having the coupling region 4 is inserted into the hub 3 protruding from the pulley 2 and the protruding hub 3 from the pulley is deformed 7 by pressure on the coupling region 4 of the shaft of the drum, for example through a hydraulic tool 8. This deformation 7 produces a tight connection between the axis 1 of the drum and the pulley 2. Thanks to the shape and position of the grooves 5 provided in the coupling region 4 of the shaft 1 of the drum, the coupling between the pulley 2 and axis 1 of the drum allows the drive of the axis 1 of the drum as a result of the rotation of the pulley 2. Thanks to the geometry of the coupling region 4 of the axis 1 of the drum, the joint The result does not include mobile elements, solving the problems of the state of the art.

En las figuras 3 y 4 se muestran diferentes realizaciones de la región de acoplamiento 4 empleada en el método de la invención. En concreto, en la figura 3 se muestra una región de acoplamiento 4 con cuatro chaflanes 9 y en la figura 4 se muestra una región de acoplamiento 4 dentada 10. Different embodiments of the coupling region 4 employed in the method of the invention are shown in Figures 3 and 4. Specifically, in figure 3 a coupling region 4 with four chamfers 9 is shown and in figure 4 a toothed coupling region 4 is shown 10.

Otras realizaciones de la región de acoplamiento 4 son igualmente posibles. Además, es posible proporcionar una región de acoplamiento 4 que combine dos o más geometrías diferentes. Other embodiments of the coupling region 4 are equally possible. In addition, it is possible to provide a coupling region 4 that combines two or more different geometries.

En la figura 5 se muestra una máquina lavadora 11 que tiene una puerta 14 en el bastidor 15 que cierra el acceso al tambor 12. El tambor está dispuesto dentro de una cuba que está suspendida en el interior del bastidor 15 de la máquina 11 mediante elementos de suspensión 16 a modo de muelles y amortiguadores. El tambor 12 puede rotar en el interior de la cuba 13 mediante el eje 1 accionado a través de la polea 2 por un motor 20. La conexión entre la polea 2 y el motor 20 se hace a través de una cinta de transmisión 17. Figure 5 shows a washing machine 11 that has a door 14 in the frame 15 that closes the access to the drum 12. The drum is arranged inside a tank that is suspended inside the frame 15 of the machine 11 by means of elements of suspension 16 as springs and dampers. The drum 12 can rotate inside the tank 13 by means of the shaft 1 driven through the pulley 2 by a motor 20. The connection between the pulley 2 and the motor 20 is made through a transmission belt 17.
