FIELD: electric engines, possible use as executive mechanism in precision devices for mechanical processing of materials. ^ SUBSTANCE: precision piezo-electric stepping movement mechanism consists of moveable part and main body with two holding blocks positioned on it in parallel plane and with shifting packet of piezo-elements between them. Holding blocks, consisting of friction elements and sliding packet of piezo-elements between them are mounted in additional body; one of holding blocks is made movable in main body. Between main body and moveable holding block a spring is positioned. Friction elements are made in form of levers held on axis held in holders with possible simultaneous rotations towards each other, while end surfaces of main and additional bodies are mounted in side surfaces of main and additional bodies with possible adjustment of compression of their internal units. ^ EFFECT: simplified manufacturing technology and increased reliability of operation. ^ 6 dwg |
