The invention relates to a device (1) for applying a non-displayed winding wire to a component (2) which is to be wound (2). The device (1) comprises a winding needle (3) which guides the winding wire, in order to wind the component (2), said winding wire being driven in a lifting manner and in a reverse manner in relation to the component (2) which is to be wound in the direction of the Z-axis. A needle carrier (4), which receives the winding needle (3), is driven by means of a crank bar (5) which is connected to the drive shaft (8) by means of a lifting journal (7) which is eccentrically arranged on a crank disk (6) which can be rotated. In order to adjust the height of the lift (h) in a simple manner and to also maintain the rotating mass as small as possible, the drive shaft (8) is embodied as a hollow shaft. A lift adjusting unit (11) is used to adjust the desired lifting height of the rotating crank disk (6), which can be activated by means of an adjusting shaft (12) which is arranged in a coaxial manner inside the hollow drive shaft (8). The central adjusting shaft (12) is displaced in a rotating manner by a second drive (13) during the synchronous operation, in relation to the drive shaft (8). A relative rotational angle differential of the adjusting shaft (12) in relation to the drive shaft (8) leads to a radial adjustment of the lifting journal (7) which is connected to the crank bar (5). |
