CURVILINEAR MOVEMENT DRIVE Russian patent published in 2020 - IPC F15B15/10 F16K31/126 B25J15/06 

FIELD: machine building.

SUBSTANCE: drive relates to machine building, robotics and can be used in pneumatic and hydraulic equipment. In the drive including a rotary mechanism, consisting of an annular bellows, on the axis of which at the ends there fixed are two plugs, which form a sealed cavity, which is made with possibility of connection to the pressure means, a flexible inextensible tie-rod is fixed in the cavities on plugs along the bellows axis. In the drive there can be installed radial guides made with possibility of interaction with the tie-rod.

EFFECT: technical solution increases efficiency of drive of curvilinear movement by increasing of power characteristics at preservation of its weight and size parameters, structural simplification, elimination of possibility of deviation from the specified trajectory.
