Vibration exciter fixing structure of vibrating screen

Abstract

The utility model belongs to the field of material screening, and discloses a vibration exciter fixing structure of a vibrating screen, which comprises a vibration exciter bearing seat, a side plate, a bearing seat pressure plate and fasteners, and the vibration exciter bearing seat is fixed on the side plate by the bearing seat pressure plate and a plurality of fasteners after penetrating through a mounting hole on the side plate of the vibrating screen; a positioning ring is concentrically welded on the side wall plate at the periphery of the mounting hole, and the inner ring of the positioning ring is a first inclined surface; an expansion sleeve is arranged between the positioning ring and the outer edge surface of the flange of the vibration exciter bearing seat, and the outer ring of the expansion sleeve is arranged to be a second inclined surface matched with the first inclined surface; the outer ring of the positioning ring is in threaded connection with an annular gland used for extruding the expansion sleeve. According to the utility model, the annular gland is utilized to extrude the expansion sleeve, so that the expansion sleeve clamps the outer edge surface of the flange of the vibration exciter bearing seat or / and the outer edge surface of the bearing seat pressure plate, thereby eliminating the radial run-out effect of the vibration exciter bearing seat, realizing the radial constraint on the vibration exciter bearing seat, and solving the problem that a fastening bolt is easy to loosen.
