Abstract
Изобретение относитс к винтовым передачам и может быть использовано дл винтовых подъемников с большим ходом. Цель - повышение надежности. Механизм содержит приводной винт 2 с ходовой гайкой 1, смонтированной в корпусе. В корпусе выполнено окно, в которое помещен ограничитель поворота гайки в виде стопора, одним концом жестко сопр женного с гайкой, а другим, снабженным головкой, взаимодействующего со стенкой окна. Трение, следовательно, боковое усилие этого взаимодействи можно уменьшить, снабдив головку антифрикционным устройством - подшипником. Сопр жение гайки с корпусом выполнено шарнирным - сферической поверхностью с промежуточным кольцом, которое своей противоположной стороной сопр гаетс плоской поверхностью с корпусом с возможностью смещени . 2 з.п.ф-лы, 3 ил.The invention relates to helical gears and can be used for high-speed screw lifts. The goal is to increase reliability. The mechanism includes a drive screw 2 with a running nut 1 mounted in the housing. In the case there is a window in which the rotation stop is placed in the form of a stopper, with one end rigidly mated with the nut and the other with a head interacting with the wall of the window. Friction, therefore, the lateral force of this interaction can be reduced by providing the head with an anti-friction device — a bearing. The coupling of the nut with the housing is made by a hinged spherical surface with an intermediate ring, which with its opposite side is mated with a flat surface with the housing with the possibility of displacement. 2 hp ff, 3 ill.
