Abstract
Изобретение относитс к фундаментам дл механизмов. Цель изобретени - повышение эффективности демпфировани колебаний на низких частотах. Фундамент включает опорную раму из балок 1 и виброизол торы 4. Кажда балка выполнена @ -образной с днищем и продольными вертикальными стенками. Концевые участки балки, длина которых не менее 1/4 длины балки, скошены на всю высоту. Виброизол торы представл ют собой прикрепленные к днищу балок волноотводы клинового вида, образованные пластинами, которые свернуты в спираль и покрыты вибропоглотителем. Пластины имеют переменную толщину, уменьшающуюс к их свободному концу. Максимальна толщина пластин равна толщине днища балок, а их длина составл ет не менее 1/2 длины балки. 2 ил.The invention relates to foundations for mechanisms. The purpose of the invention is to increase the efficiency of damping vibrations at low frequencies. The foundation includes a support frame of beams 1 and vibration isolators 4. Each beam is made @ -shaped with a bottom and longitudinal vertical walls. The end sections of the beam, the length of which is not less than 1/4 of the length of the beam, are bevelled to the full height. Vibration isolators are wedge-shaped wave conductors attached to the bottom of the beams, formed by plates that are folded into a spiral and covered with a vibration absorber. The plates have a variable thickness decreasing towards their free end. The maximum thickness of the plates is equal to the thickness of the bottom of the beams, and their length is at least 1/2 the length of the beam. 2 Il.
