Research on the Independence of the Cylinder Shaft with a Linter Machine

Abstract

In this article, theoretical studies were conducted to determine the bending strength of a saw-toothed drum shaft under load based on bending moments and displacement diagrams. The diagrams constructed as a result of theoretical work show that in rigidly supported shafts, the maximum bending moments are concentrated mainly in the support areas, while in freely supported shafts, the largest moment values are formed in the central part. This fact confirms that the type of support directly affects the location of stresses. According to the displacement diagrams, the greatest deflection of the shaft was observed in zones with intensive load effects. The diagrams of normal and equivalent stresses made it possible to identify the most dangerous sections of the shaft. This fact is of great importance in material selection and determining the safety margin. The diagrams constructed in the MathCad environment confirmed the consistency and stability of the results obtained on the basis of theoretical calculations and demonstrated the suitability of the developed mathematical model for practical application.
