Abstract

Изобретение относитс к машиностроению и может быть использовано в конструкци х роботов. Цель изобретени - уменьшение габаритов. Привод поворота исполнительного органа содержит зубчато-реечный механизм и силовой цилиндр 6, корпус 1, поршень 9, переднюю крышку 12, шток 10 с жестко закрепленной зубчатой рейкой 11. Крышка 12 выполнена составной из телескопически св занных цилиндров 14, уплотн емых поверхност ми 15. Крайние цилиндры 14 установлены жестко, остальные части - с возможностью осевого перемещени относительно друг друга. 1 ил.The invention relates to mechanical engineering and can be used in robots. The purpose of the invention is to reduce the size. The actuator rotation drive includes a gear-rack mechanism and a power cylinder 6, body 1, piston 9, front cover 12, rod 10 with a fixed gear rack 11. The cover 12 is made up of telescopically connected cylinders 14 sealed by the surfaces 15. The extreme cylinders 14 are rigidly mounted, the remaining parts are axially displaceable relative to each other. 1 il.

A stop 17 is mounted on the rod 10, on, containing a gear-rack mechanism, transmitting the axial force 25 of the power cylinder, including telescopic cylinders 14. The roller 18 is the case, the front and rear covers,

a piston and a rod with a gear rack rigidly attached thereto of a rack-and-pinion mechanism, characterized in that, in order to reduce overall dimensions, the front cover 30 is made in the form of telescopically and hermetically connected cylinders, with one extreme cylinder rigidly connected to the housing, and the other is movably mounted between the piston and an additionally inserted stop fixed to the rod.

mounted to perceive the radial forces arising in the gearing gear 2 - rail P.

The rotation drive works in the following manner.

When pressure is applied to the left cavity of the power cylinder 6, the piston 9, the rod 10 with the gear rack 11 and, accordingly, the gear of the gear wheel 2 with the output element move.
