Abstract
The article is devoted to Hirth couplings, widely used in various fields of mechanical engineering, in particular in metal-cutting machines, transport machines, manipulators. The article provides a detailed description of the Hirth coupling design, considers the algorithm of analytical calculation of couplings by various strength criteria, specifies the recommended materials of individual parts of Hirth couplings and the recommended geometric parameters of coupling teeth that ensure the required accuracy of operation. The disadvantage of the analytical calculation, which does not reflect the load distribution along the coupling tooth height, is noted. Information on the numerical calculation of Hirth couplings by the finite element method and the problems arising in this case is also provided. The importance of taking into account the friction forces arising when mating the coupling teeth is noted. The operation of the Hirth coupling used in the rotary table for the positional automatic line and the operations of the technological process used in the manufacture of the Hirth coupling are considered in detail. Information on the automated design and geometric modeling of Hirth couplings in a CAD system is provided. The scientific novelty of the work lies in the methodology of automated design of Hirth couplings developed by the authors, which can be used to accelerate the process of creating mechanical engineering objects containing such mechanisms; the developed calculation model of the Hirth coupling takes into account the influence of the initial parameters of application in the equipment on the final geometric image of the coupling, which, in turn, will be reflected in the resulting design of the sample of process equipment or another mechanical engineering object. The practical significance of the work lies in the fact that it proposes a complex of engineering support for the automated design of Hirth couplings, including design solutions based on parametric adaptive geometric 3D models in T-FLEX CAD.
