Abstract
An arrangement for changing the lever ratio of a two-armed rocker lever, particularly for the transfer movements in a press. The rocker lever is pivotally connected in a lever arm and the starting movement is capable of being tapped by another lever arm. This arrangement includes a frame, a slide guide for the rocking bearing of the rocker lever, a control device, a rotation transmission device and a nut-spindle connection for the sliding movement of the slide guide relative to the rocker lever. The rocker lever, by means of the slide guide, is disposed in a pivot bearing of a support. The support is slidably guided in the frame. The support includes the nut of the nut-spindle connection for interacting with the spindle. The control device, rotation transmission device and the spindle are arranged in the frame, and a device for fixing the position of the pivot bearing in the rocker lever is connected with the rocker lever in an operatively connected manner.
