TO THE CALCULATION OF THE GEOMETRIC PARAMETERS OF FLEXIBLE FACETS OF CAMS

Abstract

Development of recommendations for calculating the geometry of cams with flexibility facet, which have console beams with variable moment of section resistance along their length for provide strength conditions and specified deflections. Method of search, description, analogous and information analysis is used to audit the many possible decisions regarding the subject of research, the experience in the field of knitting machines of automatic half-hose machine and methods of cross and longitudinal sections from the classical position of resistance of materials. Mathematical support for the complex approach of working out of cams of various designs with flexibility working facets according to the criteria of strength, flexibility and minimization of geometric dimensions using the beam shape coefficient of deflections is presented. The advantages of beams with equal resistance along its length in comparison with homogeneous beams having constant section sizes are shown. The dependences are given, which advisable to determine the dimensions of the root and final sections of a trapezoidal beam with a free end load of concentrated force, and also formulas for calculating the shape coefficient by deflection with sufficient accuracy and convenience in engineering calculations. Further development of the theory and methodology of designing elements of knitting systems of automatic half-hose machine based on load modes, dimensions restrictions and technological process requirements. Questions are presented that contribute to a comprehensive approach to the improvement of cams designs with flexibility facet based on calculated recommendations, taking into account their specificity. The information helps to improve the quality and efficiency of cam design solutions to meet the requirements for strength and flexibility using the economic index of section.
