Experimental Study and Analysis of Dynamic Belt Tension Design and Measurement in Driver-driven Pulley Systems
Abstract
Belt drive systems are an effective means for power transmission with light weight, low cost, quietness, and efficiency. The objective of this study was to accurately measure the tension dynamic situations in the belt drive and the time used during running. The materials used were of high-quality engineering materials, which ensured accurate tension measurements. They consisted of a frame, driving pulley, video camera, v-belt, driven pulley, mirror (calibrated), and AC motor. The stability and support for other components were provided by the frame. Recording of deflections on the belt drive system was done with the use of a video webcam, while the mirror reflected the tension and deflections in the belt. Motion was transmitted by the AC motor between the two pulleys. The blower positions were at minimum and midpoints. MATLAB workspace Algorithm was used for the analysis. The largest displacement values were recorded when the blower was at the minimum position. Values of 10mm, 10mm, 12mm, 11mm, 11mm, and 12mm produced corresponding load tensions of 10N, 10N, 8N, 9N, 9N, and 8N, with the operating time of 5 to 10 minutes, respectively. At mid-point, the displacement values decreased, and the belt tension values increased significantly within the same time frame. The values obtained at midpoint were 8mm, 10mm, 11mm, 10mm, and 9mm, which produced belt load tensions of 11N, 9N, 8N, 9N, and 10N. The indication is that the measurements of the belt tension system ensured an efficient operation of belt-driven systems. Proper tensioning improved performance and also helped extend the lifespan of other components.
