Abstract
Изобретение относитс к горному машиностроению, а именно к роликовым опорно-поворотным кругам. Цель - снижение металлоемкости. Устр-во дл креплени опорно-поворотного круга включает подвижное и неподвижное коль ца (К) 1,2, соединенные с рамами 3,4 машлпы. Опорные части К 1,2 выполнены в виде кольцевых концентрических выступов 5 и впадин 6. На рамах 3,4 выполнены кольцевые впадины 7 и выступы 8. В отверсти х выступов 5 К 1 и выступов 8 рамы 4 расположены крепежные элементы 9. Кольцевые выступы 5,8 и впадины 6,7 выполнены клиновидной формы, а каждый крепежный элемент имеет конусную поверхность. С увеличением выступов 5,8 и впадин 6,7 уменьшаетс диаметр крепежных элементов 9, а следовательно, уменьшаютс размеры всего устр-ва и снижаетс металлоемкость. 1 з.п. ф-лы, 3 ил. слThe invention relates to mining machinery, in particular to roller slewing circles. The goal is to reduce metal consumption. The device for fastening the turntable includes a mobile and stationary ring (K) 1.2, connected to the frames 3.4 mashlpy. The supporting parts K 1, 2 are made in the form of annular concentric protrusions 5 and depressions 6. On frames 3,4, annular depressions 7 and protrusions 8 are made. In the openings of projections 5 K 1 and protrusions 8 of frame 4 there are fastening elements 9. Ring protrusions 5 , 8 and depressions 6,7 are made wedge-shaped, and each fastener has a tapered surface. With an increase in the protrusions 5.8 and depressions 6.7, the diameter of the fastening elements 9 decreases, and consequently, the size of the entire device decreases and the intensity of metal decreases. 1 hp f-ly, 3 ill. cl
