The results of the investigations show that the Saw wearout occurs due to the bending of the shaft under dynamic loads. The results of the investigations show that the high density of raw cotton leads higher damage to fibers during ginning. Assessment of different distances between the saws of gin and its effect to the quality of fiber; the results of the investigations shows that the Since reduction of the distance between saw from 22 mm to 14.59 mm brings about mechanically damaged filaments from 19.2 to 48%, interrupted filaments from 9.2 to 21% and thin skins with filament and fuzz from 1.66 to 3.14%. To solve this problem, we made an energy efficiency ginning machine. In old machines their saw cylinder included 130 saws, but there were much more problems described above. Because the distance between saws is 14.59 mm. As a result short cotton fiber increased in amount and it takes more time to gin. In conclusion, our new model of ginning machine enables energy efficient production, unlike old models of ginning machine, there are two saw cylinders in the new design of gin with similar parameters which are located in one worker chamber. When worker chambers consume cotton, it appears loosening and lengthened oval form. This allows reducing the density and accelerating the process of ginning and getting a qualitative fiber. As a result it provides stability and strength of shaft and increases durability of working parts
