Изобретение относитс к машиностроению и может быть использовано в приборострбении и приводах поступательного движени .The invention relates to mechanical engineering and can be used in instrumentation and actuators of translational motion.
Цель изобретени - повьшение надежности механизма путем обеашчени посто нного нахождени шариков в резьбовых канавках гайки.The purpose of the invention is to increase the reliability of the mechanism by ensuring that balls are constantly in the threaded grooves of the nut.
На фиг, 1 изображен шариковый винтовой механизм с замкнутой гайкой продольньш разрез; на фиг, 2 - вид по стрелке А на фиг, 1; на фиг. 3 - шариковый винтовой механизм с разомкнутой гайкой, продольный разрез; на фиг, 4 - вид по стрепке Б на фиг, 3.Fig. 1 shows a ball screw mechanism with a closed nut with a longitudinal section; FIG. 2 is a view along arrow A in FIG. 1; in fig. 3 - ball screw mechanism with open nut, longitudinal section; FIG. 4 is a view along the hook B in FIG. 3.
Шариковый винтовой механизм содержит винт 1, взаимодействующие с ним полугайки 2 и 3 с выполненным на дне резьбовой канавки по винтовой линии продольным пазом 4, причем обе половины гайки установлены с возможностью смещени по направл ющим подвижного исполнительного органа (не показаны) перпендикул рно оси гайки, гибкий замкнутый Сепаратор 5 с гнездами и шарики 6, размещенные в этих гнездах и резьбовых канавках винта 1 полугаек 2 и 3 при этом шарики 6 удержива- отс в гнездах сепаратора 5 губками 7, а также направл ющую 8, установленную в пазу 4,The ball screw mechanism contains a screw 1, semi-nuts 2 and 3 interacting with it with a longitudinal groove 4 arranged at the bottom of the threaded groove along a helical line, with both halves of the nut being displaced along the guides of the movable actuator (not shown) perpendicular to the axis of the nut, flexible closed Separator 5 with sockets and balls 6 placed in these sockets and threaded grooves of screw 1 of semi-nuts 2 and 3 while holding balls 6 with retaining sticks in the sockets of separator 5 with jaws 7, as well as guide 8 installed in slot 4 ,
Шариковый винтовой механизм работает следующим образом.Ball screw mechanism works as follows.
При разъеме двух полугаек 2 и 3 направл юща 8 гибкого замкнутого сепаратора 5 не выводитс из продольного паза 4 полугаек 2 и 3,.При этом шарики 6 выход т из резьбовых канавок винта I, но остаютс в резьбовых канавках полугаек 2 и 3 ,When two semi-nuts 2 and 3 are connected, the guide 8 of the flexible closed separator 5 is not brought out of the longitudinal groove 4 of semi-nuts 2 and 3. At this, the balls 6 come out of the screw grooves of screw I, but remain in the screw grooves of the semi-nuts 2 and 3,
С целью компенсации изменени длины расположенного в рабочей зоне полугаек участка гибкого замкнутого сепаратора последний может быть вьтол- нен из упругого материала на перемычках между гнездами дл шариков.In order to compensate for the change in the length of the section of flexible closed separator located in the working zone of the half-legs, the latter can be drawn out of elastic material on the bridges between the sockets for the balls.
