Изобретение относитс к устройствам гидропривода роторного колеса экскаватора.BACKGROUND OF THE INVENTION The invention relates to hydraulic drive devices for an excavator bucket wheel.
Известен гидравлический моторный блок привода роторного колеса экскаватора, установленный на стреле, включающий вал роторного колеса с гидромоторами, расположенный в расточках стрелы.Known hydraulic motor drive unit of the rotor wheel of the excavator mounted on the boom, including the shaft of the rotor wheel with hydraulic motors, located in the bores of the boom.
Дл увеличени производительпости роторного экскаватора за счет уменьшени угла подхода роторного колеса к забою в предлагаемом блоке вал роторного колеса выполнен в виде полого цилиндра с жестко закрепленными в нем гидромоторами, валы которых жестко соединены со стрелой.In order to increase the production of a rotor excavator by reducing the angle of approach of the rotor wheel to the face in the proposed unit, the shaft of the rotor wheel is made in the form of a hollow cylinder with hydraulic motors rigidly fixed in it, whose shafts are rigidly connected to the boom.
На чертеже изображен предлагаемый гидравлический моторный блок привода роторного колеса экскаватора.The drawing shows the proposed hydraulic motor unit to drive the bucket wheel of the excavator.
Он содержит высокомоментпые гидромоторы 1, 2, св занные с роторным колесом 3 через полый вал 4, установленный в подшипниках 5 и расточках роторной стрелы 6. Корпуса гидромоторов жестко св заны с валом посредством , например, шпоночного соединени 7. Валы 8 гидромоторов вместе с поршневыдш группами посредством, например, шпоночного соединени 9 жестко соединены через крышку 10 со стрелой экскаватора при помош ,и болтов. Рабоча жидкость к гидромоторам подводитс через отверсти а в валах.It contains high torque hydromotors 1, 2 connected to the rotor wheel 3 via a hollow shaft 4 mounted in bearings 5 and bores of the rotor boom 6. Hydraulic motor housings are rigidly connected to the shaft by means of, for example, a key joint 7. Shafts 8 of hydraulic motors together with a piston piston groups by means of, for example, keyed connection 9 are rigidly connected through the cover 10 to the boom of the excavator with help, and bolts. The working fluid to the hydraulic motors is supplied through the holes in the shafts.
При подаче рабочей жидкости к гидромоторам через отверсти в валах их корпуса начинают врашатьс , передава крут ший момент через вал 4 на роторное колесо 3.When the working fluid is supplied to the hydraulic motors through the holes in the shafts, their bodies begin to rise, transferring a cool moment through the shaft 4 to the rotor wheel 3.
