Abstract :

There are actual to increase the capacity of ginning with the reduction of the wear-out worker parts. The worker chamber saw cylinder and fire-grate are worker parts of gin. Substantially, the gross of saw cylinder and teeth of the saws are subjected by the wear-out. It is necessary to reduce steady-state and dynamic load on shaft for the prevention of the wear-out of saw cylinder. There are two ways of the prevention of the wear-out and preservation of fiber?s natural quality. ? The reduction of saws quantity and worker length of saw cylinder ? The division of the dynamic load on two areas not reducing the amount of the saws There are two saw cylinders in the new design of gin with like parameters which are located in one worker chamber. When worker chambers consume cotton, it appears loosening and in lengthened oval form. This allows reducing the density and accelerating the process of ginning and getting a qualitative fiber. After maximum values of moments for dangerous sections of the shaft and the moments of normal stresses as well as maximum sagging of gross were calculated. The toughness of dangerous sections of the shaft has been tested by the third hypothesis of toughness. The winding fluctuations of the shaft were explored depending on quantity of saws as well as own weight of cotton which are acting on saws. Finally the new dual-cylinder gin production half as much again as single-cylinder one and its toughness characteristic 1,7 times more.
