METHOD OF NONCONTACT DISPLACEMENT OF MOVABLE ELEMENT Russian patent published in 2004 - IPC

FIELD: fine mechanical and mechanotronics. SUBSTANCE: according to proposed method, two elements are installed opposite to each other with constant clearance in between. One of elements is made stationary and the other is installed for displacement relative to stationary element. Magnetic inserts made of magnetized ferromagnetic material are made on each element. Grooves are made on magnetic inserts, opposite grooves being made of equal width and equally spaced. Compressed fluid medium is delivered with throttling to clearance between elements. Free noncontact displacement of movable element is provided to coordinate directed along grooves each having closed or non-closed axial line in form of line of constant curvature at delivery of medium into clearance. EFFECT: improved accuracy at displacement of movable element. 4 dwg
