Description

При отсутствии сопротивлени  на рабочем инструменте со стороны разрушаемой породы шток с рабочим инструментом после удара перемеш,аетс  с большой скоростью; возникающа  при остановке штока сила инерции стремитс  оторвать инструмент от штока. Но при наличии наклонного хвостовика рабочий инструмент перемеш,аетс  не вдоль продольной оси, а по наклонной поверхности посадочного отверсти  штока. В результате этого составл юща  инерционной силы, действующей на инструмент в направлении, перпендикул рном к направл ющей планке, будет прижимать к ней рабочий инструмент и силой трени  останавливать его. При поджатии рабочего инструмента вместе со стругом к разрушаемой породе шток перемещаетс  внутрь корпуса до упора торцовой поверхности инструмента в корпус.In the absence of resistance on the working tool from the side of the rock to be destroyed, the rod with the working tool after the impact is mixed, at high speed; the force of inertia that arises when the rod stops, tends to tear the tool from the rod. But in the presence of an inclined shank, the working tool is shuffled, not along the longitudinal axis, but along the inclined surface of the stem bore. As a result, the component of the inertial force acting on the tool in the direction perpendicular to the guide bar will press the working tool against it and stop it by the force of friction. When the working tool is pressed together with the plow to the rock to be destroyed, the rod moves inside the body up to the stop of the tool face surface into the body.
