Abstract
Изобретение относитс к землеройной технике. Цель изобретени - повышение надежности и долговечности путем снижени нагрузок на шарниры звеньев механизма перемещени гибкого энергоносител . Экскаватор содержит гибкий энергоноситель 3, 5-5 размещенный в шарнирной цепи Нижн ветвь D цепи закреплена на опорной раме 2 и уложена на нее по дуге окружности радиусом RI с центром 0. Верхн ветвь С цепи закреплена на поворотной платформе 1 и расположена под ней в плоскости, параллельной опорной раме 2 по дуге окружности с радиусом R2 Переход из нижней ветви D цепи в верхнюю ветвь С осуществл етс по дуге окружности переукладки Е с радиусом R Торцовые поверхности каждого звена 5 выполнены с упорными поверхност ми М и Н и расположены под углом к оси шарнира. При поворотах платформы экскаватора опорные поверхности М или Н соприкасаютс между собой, обеспечива снижение нагрузок на оси шарниров 6 3 ил. (Л СThis invention relates to earth moving machinery. The purpose of the invention is to increase reliability and durability by reducing the loads on the hinges of the links of the flexible energy transfer mechanism. The excavator contains flexible energy carrier 3, 5-5 placed in a hinge chain. The lower branch of the D chain is fixed on the supporting frame 2 and laid on it along an arc of a circle of radius RI with center 0. The upper branch of the C chain is fixed on the turntable 1 and is located below in the plane parallel to the support frame 2 along an arc of a circle with radius R2. The transition from the lower branch of the D chain to the upper branch C is carried out along an arc of the reassembly circle E with a radius of R. The end surfaces of each link 5 are made with stop surfaces M and H and are located under angle to the hinge axis. When the excavator platform turns, the support surfaces M or H are in contact with each other, thus reducing the loads on the axles of the hinges 6 3 sludge. (Ls
