<p>Upon a spider with rigid arms (4) and thereon adjoining mounting plates (1) are placed spring bands (81,82,83). These are supported on battens (12) on the mounting plates (1) and connected via screw bolts (20). By means of the screw bolts (20) the spring tension of the leaf spring strips (71,72,73) can be varied. Upon this triangle of strips rests another spider, containing rigid arms (5) and mounting plates (2). The contact site of the leaf spring sections (71,72,73) on the battens (12) is linear and in the same way there exists a linear resting of the arms (5) on the underlying strips. The mounting plates (2) of the upper spider contain again battens (12) and clamp bolts (20) forming a linear support. The superposed spiders are guided against one another through sleeves (9), guide rod (10) and key (11). Because of the fact that there exist leaf spring sections, the mounting height of the vibration dampers is very small. By means of the screw bolts (20) the spring tension can be changed in a very simple manner. The vibration damper is intended as vibration insulator for mechanical vibrations of very low frequencies.</p> |
