Методика розрахунку самонатяжної пасової передачі

Abstract

Приведено опис конструкції; робота і методика по визначенню основних параметрів, і розрахунок самонатяжної пасової передачі. The paper describes the design and operation automatic tension reverse V-belt drive, graphics display presents the stress changes in various belt drives, with different creation belt. Which implies that the transmission belt of the same rated load in all gears in the branches of the tension and friction are the same size. However, with increasing load transferred, there is an increase in the intensity of the bearings in gear with a fixed axle pulleys, and is less intense in automatic tension transmission. To this end, we consider automatic tension belt drive with tensioning roller in which the belt tension is automatically created by the reactive moment, depending on the size of the transmitted load at any given time. This mode of transmission is caused by properly chosen geometrical parameters. We have developed a V-belt drive automatic tension, the technique of calculating automatic tension reverse Vbelt transmission and graphs to determine the main parameters of the transfer. The study found that as the center distance and the length of the lever tensioner angle of wrap a belt drive pulley is constantly increasing. From which it follows that the proposed construction automatic tension V-belt transmission in the most rational drive cars with medium and higher center distance. Thus, we conclude that the developed method allows to determine the basic parameters of rational automatic tension reverse V-belt transmission and to produce its power and kinematics calculation using the current regulatory parameters for the calculation of belt drives.
