Abstract
Изобретение предназначено дл использовани в лесопильной промышленности, а именно в конструкции лесопильных рам. Цель изобретени - повышение производительности и надежности лесопильных рам. При работе лесопильной рамы во врем подхода пильной рамки к нижней мертвой точке пильна рамка 2 замедл ет движение, а дополнительно уравновешивающие 9, двига сь под действием сил инерции вверх по направл ющим 6, расположенным параллельно шатуну 5 и пильной рамке 2, сжимают пружины 11. Усили сжатых пружин 1 1 передаютс через упоры 10 на пильную рамку 2 и шатун 5, снижа динамические нагрузки механизма. При приближении пильной рамки 2 к верхней мертвой точке направление движени грузов 9 и действующих сил мен ютс на противоположное, снижа динамические нагрузки, возникающие в механизме . Подбором жесткости пружин 11 достигаетс движение уравновешивающих грузов 9 в противофазе с движением пильной рамки. Перемещением упоров 10 производитс настройка частоты собственных колебаний грузов 9 в случае различи характеристик пружин 11 и их возможных изменении 1 з.п.ф-лы, 4 ил. Ј (ЛThe invention is intended for use in the sawmill industry, namely in the construction of sawmill frames. The purpose of the invention is to increase the productivity and reliability of sawmill frames. When the sawmill is operating, when the saw frame approaches the bottom dead center, the saw frame 2 slows down movement, and additionally balancing 9, moving under the action of inertia forces upward along guide 6, parallel to the connecting rod 5 and saw frame 2, compress the springs 11. The forces of the compressed springs 1 1 are transmitted through the stops 10 to the saw frame 2 and the connecting rod 5, reducing the dynamic loads of the mechanism. When the saw frame 2 approaches the top dead center, the direction of movement of the loads 9 and the operating forces change to the opposite, reducing the dynamic loads that occur in the mechanism. By selecting the stiffness of the springs 11, a movement of the counterbalancing weights 9 is achieved in antiphase with the movement of the saw frame. By moving the lugs 10, the natural vibration frequency of the weights 9 is adjusted in case of differences in the characteristics of the springs 11 and their possible changes 1 Cp f-crystals, 4 Il.
