Experimental Study and Analysis of Dynamic Belt Tension Design and Measurement in Driver-driven Pulley Systems
Abstract
Belt drive systems are effective means for power transmission with light weight, low cost, quietness and efficiency. The objective of this study was to measure accurately the tension dynamic situations in belt drive and the time used during the 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 current motor. The stability and support for other component were provided by the frame, recording of deflections on the belt drive system was done with the use of a video web cam 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 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 operated time of 5 to 10 minutes respectively. At mid-point, the displacement values decreased and belt tension values increased significantly with 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 extends the lifespan of other components.
