DEVELOPMENT OF AN EFFECTIVE DESIGN AND CALCULATION FOR THE BENDING OF A GIN SAW CYLINDER

Keywords

The bending stiffness of the saw cylinder, the function of the influence of the thickness of the saw blades and the friction forces between them, the function of the influence of elastic deformation, the elastic moduli and the cross-sectional area, bending, deflection of the saw cylinder, bending vibrations, potential and kinetic energy, the influence of design factors.

Abstract

The article presents a constructive diagram of a new saw cylinder and the results of a study of the bending of a gin saw cylinder, determining how to find the deflection and technological gaps, especially between the saw and grates of the gin and linter, within the limits determined by the technological regulations for ginning and lintering. The process of bending vibrations of a gin saw cylinder, having a package of working steel saws and aluminum gaskets between them, compressed by the longitudinal compression force communicated by the central shaft, is considered. The results of the calculation of the bending of the spline shaft, dusty gin cylinder are presented.
