FIELD: physics; acoustics.
SUBSTANCE: invention concerns a clamp of a system of the drum-type mechanism of a tremolo string musical instrument. The clamp of a system of the tremolo mechanism is located coaxially with a drum-axis of the tremolo mechanism. The clamp has the shared details with the tremolo mechanism, such as a drum, the case, the basic bearing of a drum-axis. By means of the screw screwed in a carving aperture of the case with possibility of support in a spring ring, located in a ring flute of the case, the clamp mechanism disconnects from at the weakened screw and the clamp mechanism puts into operation at the tightened screw. It is carried out at the expense of latching of the bearing of the castor having an internal cavity set on hard planting to an external ring. In an internal cavity there is one of two preliminary compressed ring-shaped springs which rests with one end against the right part of central washer perpendicularly located concerning a plane of the central washer having rotation possibility, and with other end the spring rests against a wall of a castor groove. Thus the left part of a lath of the central washer rests against the top wall of a groove of a disk by means of one end preliminary compressed by the second ring-shaped spring located in a cavity of the disk, having a groove. Thus the disk is rigidly fastened on a drum-axis by means of the carving end of a drum-axis, a nut, a washer and a brace plug which allows to keep the necessary backlash providing sliding of the central washer concerning a disk and a castor.
EFFECT: keeping of a system of the tool by a clamp in admissible limits at breakage of one of the strings, and also realisation of the guaranteed return of the mechanism of a tremolo in a starting position.
