'A', 'B', 'C', 'D' and 'E'. The categorization of this is based on the cross sectional size of the belt and the amount of power to be transmitted by the belt. The dimensions of various sections of the V-belt are shown below. The included angle of the V-Belts is 40 Degrees. Classical. This standard was developed in the 1930s. It now comes in six sizes (A, B, C, D, E and Z). Narrow. Procedure 5: Selection of Belt Size Using the given center distance and the size of the large and small sheaves selected, calculate the belt length. For this purpose the following equation is used. C = Center Distance D = Outer Diameter of Large Sheave d = Outer Diameter of Small Sheave Belt Size = 2C + 1.57 (D+d) + (D-d)2 4C There are several industry standards for the types and sizes of v-belts. Each type features the basic trapezoidal shape but has different dimensions. Standard v-belt. Standard v-belts are common in power transmission applications. These v-belts come in various types, as shown in Table 1. Each type varies from one another with respect to its Simply measure from the 1" mark across the top of the belt. Common widths range from ½" to as wide as 1½" to indicate whether you need anything from an A belt all the way up to an E belt. Measuring the V-Belt Length. There are a few different ways you can measure the length of a V-belt. In this article we'll review some V- belt basics to help you make better sense of which belt to use in a given ap- plication to make your belt drives last longer, run more eficiently, and save you downtime and money. Size Isn't Everything. Take a look at the accompanying chart (Figure 1). Locate the corresponding belt type and size on the chart: Once the current belt type and size have been identified, locate the corresponding size and type on the V-belt conversion chart. The chart will provide information on the different types of V-belts and their corresponding sizes. eCkN.
