Description

При вращении вертикального вала 7 эксцентрик 8 действует на конус 4 через радиально-упорные подшипники 9.When the vertical shaft 7 rotates, the eccentric 8 acts on the cone 4 through angular contact bearings 9.

Распределительный конус 4 благодар  упругой прокладке 2 под действием эксцентрика 8 совершает круговые колебательные движени  относительно оси сердечника , причем диаметр окружности, описываемой конусом, превышает диаметр окружности , описываемой корпусом 1. Разность между этими диаметрами определ етс  величиной эксцентриситета.The distribution cone 4 due to the elastic gasket 2 under the action of the eccentric 8 performs circular oscillatory movements about the core axis, and the diameter of the circle described by the cone exceeds the diameter of the circle described by the housing 1. The difference between these diameters is determined by the value of eccentricity.

В результате происходит зшлотнение бетонной смеси.As a result, there is sloshing of the concrete mix.

Изобретение позвол ет упростить конструкции сердечников и повысить их надежность .The invention allows to simplify the design of cores and increase their reliability.
