A contribution to the tractor gearbox calculation

Implementation of cumulative damage method, used in tractor gearbox lifetime calculation, implies the application of the tractor load spectra diagrams. Some gears in complex tractor gearbox can be included in several groups of speed, and therefore this gears are different loaded and participate unequal in lifetime of every group of speed. In such case standard load spectra curve of each group of speed is placed on different position in spectra diagram, which makes confusion in calculation. In this paper is proposed the procedure how to combine several load spectra curves of one gear to get more reliable results.
