【摘要】：鼓形齿联轴器作为重要的传递转矩和运动的部件,具有结构紧凑,性能安全可靠,传递效率高等优点,普遍应用于冶金、机械、船舶等行业。鼓形齿联轴器在工作过程中产生的冲击力、振动及噪声会对鼓形齿联轴器的承载性能和使用寿命产生重要影响。基于上述考虑,本文基于联轴器啮合原理的理论基础,利用仿真软件对GCL13型鼓形齿联轴器进行静力学和运动学仿真分析。本文主要研究工作如下:首先,详细介绍了联轴器传动原理及齿廓修形的相关理论,并对GCL13型鼓形齿联轴器进行强度理论计算。其次,利用CAXA软件和SolidWorks软件建立GCL13型鼓形齿联轴器的三维实体模型,然后再导入HyperMesh软件中进行单元选择、网格划分、接触的定义、约束和载荷施加,对GCL13型鼓形齿联轴器进行静力学仿真分析,得出该鼓形齿所受应力在其许用应力范围内。再次,通过HyperMesh软件建立GCL13型鼓形齿联轴器整体有限元模型,利用模态分析,提取了联轴器的前八阶固有频率和阵型。分析低阶模态,算出该鼓形齿联轴器的第一阶临界转速,与理论公式计算结果相差在5%以内。且该联轴器工作转速低于第一阶临界转速,故不会发生共振现象。最后,对不同位移圆半径的鼓形齿联轴器进行静力学和动力学仿真分析,将仿真结果进行综合对比分析,得到了该型号鼓形齿联轴器应力和运动平稳性随位移圆半径参数变化的规律,更全面地掌握了鼓形齿联轴器实际工作时的力学特性,为鼓形齿联轴器优化方面的研究提供了依据。
[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.
