Description

ВИ.И- руко тки) служит дл поворота кривошипа 7 и его фиксации.VI.I- handles) serves to rotate the crank 7 and its fixation.

Регулировка жесткости опоры осуществл ет с изменением жесткости упругого элемента 4 при повороте вала 5. Сечение вала 5 выполнено некруглой формы, например овальной. При установке вала так, чтобы больша ось ;вального сечени располагалась параллельно выбранному направлению колебаний, жесткость опоры увеличиваетс . При установке малой оси овального сечени параллельно направлению колебаний жесткость опоры уменьшаетс .Adjusting the rigidity of the support is carried out with a change in the rigidity of the elastic element 4 when the shaft 5 is rotated. The section of the shaft 5 is non-circular, for example oval. When installing the shaft so that the large axis; the total cross section is parallel to the chosen direction of oscillation, the rigidity of the support increases. When installing a small axis of the oval section parallel to the direction of oscillation, the rigidity of the support decreases.

Присоединив к кривошипу 7 шатун 6 другой опоры, можно поворотом руко тки 10 одновременно и синхронно регулировать жесткость обеих опор.By connecting the crank 7 to the crank 7 of the other support, you can turn the handle 10 simultaneously and simultaneously synchronously adjust the stiffness of both supports.

Описанное выполнение опоры позвол ет просто и плавно регулировать ее жесткость, в том числе и на ходу, без остановки вибрационной машины.The described embodiment of the support allows its rigidity to be easily and smoothly adjusted, including on the fly, without stopping the vibrating machine.

Claims

1. Adjustable elastic support for vibratory machines, containing a rigid holder, an elastic element in the form of a sleeve fixed therein and a device for adjusting the stiffness of the elastic element, characterized in that, in order to simplify and ensure the smoothness of stiffness adjustment, the stiffness adjustment device is made in the form of a shaft with a non-circular cross section installed with a tension in the bore of the sleeve, and a mechanism for turning this shaft.

2. A friend of a support according to claim 1, characterized by the fact that the mechanism for rotating the shaft is formed by a crank, a connecting rod eccentrically connected to the shaft, and a drive for rotating the crank.
