AGGREGATE TO APPLY METAL POWDERS COATINGS ON INNER SURFACES OF CYLINDRICAL PIECES Russian patent published in 1994 - IPC

FIELD: electrochemical industry. SUBSTANCE: aggregate has movable relatively to heating source bed-frame, on guides of which front and rear carriages are mounted. Carriages are capable for independent longitudinal movement. Front carriage has drive for piece rotation. Exciter of revolving oscillations is located in rear carriage. It is made in the form of hard eccentric and at least one spring-loaded to it braking roller, located on lever. Shaft of lever is mounted so as to be capable to make planetary movement around axis of rotation of eccentric. Mean to regulate braking roller pressure degree to eccentric is made as bush, that is rigidly fixed on pulley of drive of Exciter of revolving oscillations, and at least one lid, mounted in lid so as to be capable to turn relatively to axis of rotation of lever. During engagement of braking roller with eccentric surface they produce periodically changing instant of resistance, that causes periodical change of rotation rate of piece, mounted in centers of front and rear carriages. EFFECT: aggregate is used in electrochemical industry. 2 cl, 4 dwg, 1 tbl
