Study of the Drive Characteristics Affecting the Power Loss of V-Belt Drives

The V-belt drive heats up during power transmission, i.e. a significant part of power loss turns into heat and is transferred to the environment. In this paper, the temperature rise in the V-belt was studied as loss intensity as a function of the drives parameters. It was justified in the scope of the major characteristics affecting power loss that by ideally selecting the parameters of the V-belt drive power loss can be measurably reduced. Based on earlier results as well, a regression model was used to examine the temperature rise in the V-belt. With the help of analysis of variance (ANOVA), the magnitude of the effect of each drive parameter was determined on the warming of the V-belt. According to our results, the most relevant drive parameter is the pulley diameter.
