DIGITAL ACTUATOR WITH ROTARY-TRANSLATIONAL EFFECT

摘要

A digital rotary-translational actuator comprises a cylinder with output rod with front and back covers in which in sequence with formation of order cavities with feeding channels order pistons are placed, with restrictors of relative movement, and a motor installed on the back cover. In the axial recesses of the back cover and the pistons of lower orders an additional shaft is placed hermetically with possibility of turn, its outer cylindrical tail element is kinematically through a toothed transmission connected to the output shaft of stepping motor, and the other slot end of the shaft with length larger than total travel of the order pistons is placed in axial recesses of the piston of the higher order and output rod and is connected with possibility of motion to the slot bushing that is fixed in the axial opening of the piston of the higher order.
