Abstract

Устройство (1) для сборки шин, содержащее барабан (2), образованный двумя полубарабанами (7, 8), которые являются зеркальными относительно центральной плоскости (4) барабана (2), выполнены с возможностью относительного перемещения и соединены в угловом направлении с соответствующим валом (5; 16) для вращения вокруг общей оси (3), причем устройство (1) оборудовано первым приводным устройством (6) для вращения барабана (2) вокруг оси (3) и непрерывного изменения расстояния между двумя полубарабанами (7, 8) и вторым приводным устройством (39) для перемещения барабана (2) в радиальном направлении между конфигурацией максимального радиального расширения и конфигурацией максимального радиального сжатия, причем первое приводное устройство (6) расположено снаружи барабана (2) для перемещения в осевом направлении полубарабанов (7, 8) посредством относительного телескопического перемещения соответствующих валов (5, 16), а второе приводное устройство (39) расположено внутри барабана (2) и функционирует независимо от первого приводного устройства (6) и перемещения валов (5, 16) полубарабанов (7, 8).The device (1) for tire assembly, comprising a drum (2) formed by two semi-reels (7, 8), which are mirrored relative to the center plane (4) of the drum (2), is made with relative movement and connected in the angular direction with the corresponding shaft (5; 16) for rotation around a common axis (3), and the device (1) is equipped with the first drive device (6) for rotating the drum (2) around the axis (3) and continuously changing the distance between the two semi-reels (7, 8) and the second actuator (39) to move b arabana (2) in the radial direction between the configuration of maximum radial expansion and the configuration of maximum radial compression, the first drive device (6) is located outside the drum (2) to move in the axial direction of half-drums (7, 8) through relative telescopic movement of the respective shafts , 16), and the second drive unit (39) is located inside the drum (2) and operates independently of the first drive unit (6) and the movement of the shafts (5, 16) of the half-reels (7, 8).
