In practice, the cost of a gearbox plays very important role in trade. Therefore, reducing gearboxes is an task not only when manufacturing but also designing them. order to reduce gearbox, there are many solutions which determining optimal partial gear ratios effective measure. This because it size, mass depends greatly on ratios. work presents method for calculating function two-stage helical...

In this article, modeling and optimization of power consumption of two–stage compressed air system has been investigated. To do so, the two – stage compressed air cycle with intercooler of FAJR Petroleum Company was considered. This cycle includes two centrifugal compressors, a shell, and a tube intercooler. For modeling of power consumption, actual compressors isentropic efficiencies and inter...
