Belt driven vibratory apparatus

摘要

A vibratory apparatus (10) for use with associated vibratory conveyance equipment includes a pair of counter-rotating shafts (22,24) respectively carrying counter-rotating eccentrically mounted weights (28,30) for generating vibratory forces attendant to counter-rotation of the shafts. Economical manufacture of the apparatus is promoted by providing a toothed belt drive (36) for effecting counter-shaft rotation, with externally-mounted bearing assemblies provided to facilitate periodic bearing maintenance. A housing of the apparatus is configured as a fabricated composite beam assembly to promote economical manufacture, and mounting and integration of the vibratory apparatus with associated vibratory feed equipment. <IMAGE>
