Description
воздуха в рабочую полость, вращают маховик 7 в направлении, при котором гайка 4 перемещаетс вверх по штоку 3 до необходимого положени . После падени давлени в рабочей полости поршень 2 и шток 3 вместе с гайкой 4 начнут опускатьс до тех пор, пока гайка не упретс в корпус цилиндра 1.air into the working cavity, rotate the flywheel 7 in the direction in which the nut 4 moves up the stem 3 to the desired position. After the pressure in the working cavity drops, the piston 2 and the rod 3 together with the nut 4 will begin to fall until the nut stops at the cylinder body 1.
Предмет изобретени Subject invention
Пневматический домкрат, содержащий силовой цилиндр с поршнем и штоком, взаимодействующим с подъемной кареткой, и фикси рующую гайку, отличающийс тем, что. с целью увеличени рабочего хода поршн и повышени надежности в работе, шток поршн выполнен со шпоночным пазом, идущим по винтовой линии, а направл юща гайка снабжена винтовым выступом, перемещающимс по винтовому пазу щтока до упора направл ющей гайки в силовой цилиндр, при этом щпоночный паз штока и винтовой выступ направл ющей гайки образуют самотормоз шуюс винтовую пару.A pneumatic jack comprising a ram with a piston and a rod cooperating with a lifting carriage and a locking nut, characterized in that. In order to increase the working stroke of the piston and increase the reliability of operation, the piston rod is made with a key groove running along a helical line, and the guide nut is equipped with a screw lug that moves along the screw groove of the brush until the guide nut stops against the power cylinder, while the keyway groove The stem and screw lug of the guide nut form a self-braking shuyus screw pair.
