APPARATUS FOR DETERMINING AXIAL FORCES ACTING UPON CHAIN TRANSMISSION SPROCKET TEETH Russian patent published in 1998 - IPC

FIELD: testing and dynamometric equipment. SUBSTANCE: apparatus has sprocket with one tooth provided with radial recesses extending from slot of this tooth to sprocket hub. Two depressions are made in lower part of tooth on its end surface between recesses in symmetry with tooth axis. Longitudinal distance between recesses in lower part of tooth exceeds axial distance. Tensometers positioned in depressions in symmetry one with respect to another are interconnected and are sensitive only to axial forces. EFFECT: increased efficiency in determining axial forces acting upon chain transmission sprocket teeth and enhanced reliability in operation. 2 dwg
