FIELD: drives for curvilinear motion of actuating mechanisms. SUBSTANCE: proposed drive includes bellows used for connection with pressure creating unit; centers of external and internal circles of part of bellows corrugations do not coincide; distances between centers of internal and external circles are different and are selected for ensuring required radii of curvature of different sections of line connecting the centers of external and internal circles of corrugations. Besides that, surface on which sections connecting the centers of internal and external circles of corrugations lie is curvilinear. According to another variant, proposed drive includes bellows used for connection pressure creating unit; centers of external and internal circles of at least part of corrugations do no coincide; surface on which sections connecting the internal and external circles lie is curvilinear. EFFECT: fast response of drive. 3 cl, 9 dwg |
