Abstract

FIELD: mechanical engineering. SUBSTANCE: rotation link 2 and reciprocation link 3 are mounted inside housing 1. Rolling bodies 6 are interposed between the links. The links are pressed under the action of compressed gas, supplied to pressure-tight chamber 7, and spring 9. When link 2 rotates, bodies 6 roll over faces of links 2 and 3. As a result link 3 reciprocates. EFFECT: improved design. 2 cl, 1 dwg

Description

Изобретение относится к машиностpо- ению, к механизмам для преобразования движений. The invention relates to mechanical engineering, to mechanisms for converting movements.

Цель изобретения повышение надежности за счет обеспечения постоянного силового замыкания механизма. The purpose of the invention is to increase reliability by providing a constant power circuit of the mechanism.

На чертеже представлен общий вид механизма. The drawing shows a General view of the mechanism.

Механизм содержит корпус 1, размещенные в нем звено 2, установленное с возможностью вращения, и звено 3, установленное с возможностью возвратно-поступательного перемещения по направляющим 4 и 5, выполненными шариковыми. Между звеньями установлены тела 6 качения, предназначенные для взаимодействия с круговыми волнообразными поверхностями звеньев. Механизм содержит также устройство для поджима звеньев, выполненное в виде герметичной камеры 7, одной из стенок которой является наружная торцевая поверхность звена, а другой подвижная в осевом направлении стенка 8. Кроме того, механизм содержит пружину 9, установленную соосно звену для возвратно-поступательного перемещения с возможностью взаимодействия с подвижной стенкой камеры. The mechanism includes a housing 1, a link 2 mounted therein, mounted rotatably, and a link 3 mounted with the possibility of reciprocating movement along the guides 4 and 5, made ball. Between the links installed body 6 rolling, designed to interact with circular wavy surfaces of the links. The mechanism also includes a device for tightening the links, made in the form of a sealed chamber 7, one of the walls of which is the outer end surface of the link, and the other axially movable wall 8. In addition, the mechanism includes a spring 9 mounted coaxially to the link for reciprocating movement with the ability to interact with the moving wall of the camera.

Механизм работает следующим образом. The mechanism works as follows.

При вращении звена 2 тела 6 качения под действием момента сил трения катятся по поверхности торцов 2 и 3, в результате чего звено 3 совершает возвратно-поступательное движение. Прижим звеньев друг к другу обеспечивается путем подачи сжатого газа в герметичную камеру 7, который за счет своей упругости обеспечивает силовое замыкание механизма. В случае падения давления в источнике (на чертеже нет) сжатого газа и, следовательно, в камере пружина 9 компенсирует это падение давления, сохраняя постоянство усилия поджима и повышая тем самым надежность работы механизма. When the rotation of the link 2 of the rolling body 6 under the action of the moment of friction forces roll along the surface of the ends 2 and 3, as a result of which the link 3 makes a reciprocating motion. The pressure of the links to each other is ensured by supplying compressed gas to the sealed chamber 7, which due to its elasticity provides a force circuit of the mechanism. In the event of a pressure drop in the source (not shown) of compressed gas and, therefore, in the chamber, the spring 9 compensates for this pressure drop, while maintaining a constant pressing force and thereby increasing the reliability of the mechanism.
