The V-belt Drive Abstract: The v-belt drive are widely used in all kinds of machanics , So to understand and know how to design it is very necessary .The v-belt and the pulley are two most important parts of v-belt drive ,the centre distance ,the diameter of the pulleys and the rpm of the pulleys are the most essential parameters of the v-belt drive . The v-belt drive has a drive pulley and a power take-off pulley , we design their diameters in the basis of speed ratio . Key words: v-belt drive centre distance pulley diameter speed ratio The V-belt drive has a drive pulley and a power take-off pulley and an endless V-belt rotating around both pulleys. This V-belt drive is equipped with a torque measuring device in that an rpm sensor is assigned to both the drive pulley and the power take-off pulley , which continuously detects the pulley rpm, the two rpm sensors are connected with an electronic control which determines the gear ratio between the drive and the power take-off pulleys from the detected rpm, a calibration device, which associates a set gear ratio with a defined torque is connected with the electronic control , and the electronic control is connected with an electronic evaluator . The invention relates to the provision of a V-belt drive, where it is possible to determine the torque existing at different drive loads by simple means and in an optimal manner, as a function of the cooperating parts of the V-belt drive, i.e. drive pulley, power take-off pulley and V-belt, and to control and adjust it in this way. The V-belt drive in accordance with the invention is equipped with a torque measuring device, which uses the depth of penetration of the V-belt in the V-belt grooves of the drive and power take-off pulleys, which heretofore often had been considered to be slippage and had not been taken into account, as well as the variable gear ratio caused thereby and compares this gear ratio, which con
