CURVILINEAR TRAVEL DRIVE WITH RING BELLOWS (VERSIONS) Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: drive is designed to provide curvilinear travel of working member. Proposed drive contains two bellows one of which is placed inside the other, and ring space between bellows is stopped at end faces and is designed for connection with pressure building device. Space of inner bellows is open, and axes of bellows do not coincide. According to other designed version, drive contains two bellows, one nested inside the other, and ring space between bellows is stopped at end faces and is designed for connection with pressure building devices, space of inner bellows being made open and at least one of bellows made asymmetrical so that axes passing through centers of inner and outer contours of corrugations of said bellows do not coincide. EFFECT: enlarged sphere of application. 6 cl, 8 dwg
