Abstract

The invention discloses a light-load synchronous wheel type roller mechanism, and belongs to the technical field of material conveying equipment. The invention adopts a non-penetrating fixed shaft, is rotationally connected with rollers at the left side and the right side through end bearings, integrates a synchronous wheel and a limiting fixed structure in the middle, and forms gaps adapting to synchronous belts at the two sides of the synchronous wheel by utilizing an upper limiting ring and a fixed ring, so that a single synchronous belt can drive a plurality of arranged roller mechanisms simultaneously. Compared with the traditional roller conveying line, the roller conveying line can complete full-line transmission by only a single synchronous belt, the roller spacing can be freely adjusted, and the synchronous belt transmission has the advantages of low noise and high precision, and is particularly suitable for light-load material conveying scenes sensitive to noise. The invention has compact structure, convenient installation and maintenance, and can effectively simplify the structure of the conveying line and reduce the manufacturing cost and the operation noise.
