[Abstract]:As an important part of transmission torque and motion, drum gear coupling has the advantages of compact structure, safe and reliable performance, high transfer efficiency and so on. It is widely used in metallurgy and machinery. In ships and other industries, the impact force, vibration and noise generated by the drum gear coupling in the course of operation will have an important impact on the bearing capacity and service life of the drum tooth coupling. Based on the theoretical basis of the engagement principle of the coupling, the static and kinematic simulation analysis of the GCL13 type drum gear coupling is carried out by using the simulation software. The main research work of this paper is as follows: first of all, This paper introduces the transmission principle of coupling and the relevant theory of tooth profile modification in detail, and calculates the strength of GCL13 type drum gear coupling. Secondly, the three-dimensional solid model of GCL13 type drum tooth coupling is established by using CAXA software and SolidWorks software. Then the element selection, mesh division, contact definition, constraint and load are introduced into HyperMesh software. The static simulation analysis of GCL13 type drum tooth coupling is carried out, and the stress of the drum tooth is found to be within its allowable stress range. The integral finite element model of GCL13 type drum tooth coupling is established by HyperMesh software. The first eight natural frequencies and formation patterns of the coupling are extracted by modal analysis. The first critical speed of the drum tooth coupling is calculated by analyzing the low order modes. The difference between the calculated results and the theoretical formula is less than 5%, and the working speed of the coupling is lower than the first critical speed, so there is no resonance phenomenon. Finally, the static and dynamic simulation analysis of drum tooth coupling with different displacement circle radius is carried out. By comparing and analyzing the simulation results, the variation of stress and motion stability with the displacement radius parameters is obtained, and the mechanical characteristics of the drum tooth coupling are more comprehensively grasped. It provides a basis for the optimization of drum gear coupling.
