CONVEYER WITH SUSPENDED BELT Russian patent published in 2004 - IPC

FIELD: conveyer building industry, namely conveyers with suspended belts secured by roller support. SUBSTANCE: conveyer has belt, brackets connected to belt sides and having double feed rollers, tubular guiding means for feed rollers movement thereon. Guiding means are closed in vertical plane and consist of linear parts located into span between drive and tension pulleys and between arc-shaped parts extending along circular arcs. Arcshaped parts are arranged in area of belt turn around drive and pulley drums. Arcshaped parts of guiding means are pliable and are formed as spiral tension springs with free ends connected to linear guiding means parts through bushings. One bushing end have outer thread engaging corresponding inner thread of guiding means. Another bushing end has spiral groove cooperating with spring coils. Outer diameter of each spring is equal to that of tubular guiding means. EFFECT: increased efficiency and reliability due to arc-shaped parts flexibility in different planes, which compensates inaccuracies during conveyer moving components production and assemblage. 3 cl, 5 dwg
