Description
(54) УСТРОЙСТВО ДЛЯ ПЕРИОДИЧЕСКОГО ПОВОРОТА(54) DEVICE FOR PERIODIC TURN
1one
Изобретение относитс к области машиностроени , а в частности к поворотным механизмам.The invention relates to the field of mechanical engineering, and in particular to rotary mechanisms.
Известны устройства дл периоди- j ческого поворота, планшайбы которых соединены с силовым приводом через храповой механизм, водило и шатун,шар нирно св занный с ведущим элементом привода, а механизм фиксации выпол- 10 иен в виде тормоза и элемента допол- . нительной фиксации последнего 1 .Devices for periodical rotation are known, whose faceplates are connected to a power drive through a ratchet mechanism, a carrier and a connecting rod, which is synchronously connected to the driving drive, and the locking mechanism is made in the form of a brake and an additional element. body fixing last 1.
Недостатком известного устройства вл етс достаточно большие габариты.A disadvantage of the known device is rather large dimensions.
Цель изобретени - уменьшение га- j баритов устройства и улучшение компоновки .The purpose of the invention is to reduce the device baritas and improve layout.
Дл этого ведущий элементпривода выполнен в виде кривошипа, установленного с возможностью BO3BpaTHO-noc-2Q тупательного движени . Элемент дополнительной фиксации тормоза выполнен в виде электромагнита, а силовой привод выполнен в виде лопастного двигател .25For this, the drive master is designed as a crank, which is installed with the blunt motion BO3BpaTHO-noc-2Q. The element of additional fixation of the brake is made in the form of an electromagnet, and the power drive is made in the form of a blade engine .25
На фиг. 1 изображен предлагаемый механизм, разрез; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - разрез Б-Б -на фиг. 2; на фиг. 4 - разрез В-В на фиг. 2..FIG. 1 shows the proposed mechanism, the cut; in fig. 2 shows section A-A in FIG. one; in fig. 3 - section BB — on FIG. 2; in fig. 4 shows a section B-B in FIG. 2 ..
На корпусе 1 установлен вал 2 храпового колеса 3. Храповик 4 расположен на водиле 5, которое установлено на валу 2 свободно. Водило 5 соединено с кривошипом 6 при помощи шатуна 7 с двум шарнирами. На валу 2 храпового колеса 3 жестко насажена планшайба 8 с тормозным барабаном 9. На крышке 10 корпуса 1 под планшайбой 8 расположены колодки 11 фрикционного тормоза. Колодки 11 при помощи т г 12, 13, 14 через пружину 15 соединены с двуплечим рычагом 16, второе плечо которого размещено внутри корпуса. Дл ограничени хода кривошипа 6 имеютс регулируемые упоры 17 и 18. На корпусе 1 установлен электромагнит 19. Храповик 4 пружиной 20 поджат к храповому колесу 3. Кривошип 6 установлен на валу лопастного двигател 21, совершающего возвратно-вращательное движение.On the housing 1 is installed shaft 2 of the ratchet wheel 3. Ratchet 4 is located on the carrier 5, which is mounted on the shaft 2 freely. The carrier 5 is connected to crank 6 by means of a connecting rod 7 with two hinges. On the shaft 2 of the ratchet wheel 3, a faceplate 8 with a brake drum 9 is rigidly mounted. On the cover 10 of the housing 1, under the faceplate 8, pads 11 of the friction brake are located. The pads 11 are connected to a two-arm lever 16 via a spring 15 by means of tg 12, 13, 14, the second arm of which is located inside the case. To limit the stroke of the crank 6, there are adjustable stops 17 and 18. Electromagnet 19 is mounted on housing 1. Ratchet 4 is spring loaded against ratchet wheel 3. Crank 6 is mounted on the shaft of a rotary vane 21 motor.
Механизм работает следую чим образом .The mechanism works in the following way.
