DEVICE FOR SUPER FINISHING TREATMENT Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: device has a floating assemble of bars 3 set in holder 4 fitted on axle 5 for permitting rocking. Axle 5 is provided with space 6 filled with air and mounted for permitting reciprocation and rocking with respect to the center of the chute. The reciprocation is arrested with stop 11. Since bars 3 are mutually movable and the assemble of bars may move in holder 4 as a whole as well as holder 4 may rock itself, the axle of rocking of bars always be in coincident with the center of gravity of the chute to be treated. Air in space 6 of axle 5 is a damper for abrasive bars 3 when an undesired periodic load occurs. EFFECT: improved design. 2 dwg
