摘要
随着光纤激光应用的成熟和普及,在汽车制造、船舶、医疗和航空航天等方面得到广泛的应用。为了进一步提高光纤激光设备的高可靠性、高稳定性和高效率,有必要对行星减速器进行有限元分析和模态分析。通过建立行星齿轮减速器的简易模型,以行星齿轮减速器为研究对象,分析其传动过程中的载荷及工况,利用三维软件ANSYS建立行星齿轮减速器的三维模型,并将模型导入至有限元分析软件ANSYS Workbench中,对三维模型进行了静力学有限元分析和模态分析。试验研究表明,整个行星减速器的等效应力和应变主要分布在太阳轮与3个行星齿轮啮合处,且最大应力发生在太阳轮的齿根圆角处,其最大值为119.64 MPa;最大应变发生在啮合齿轮齿根处,最大位移发生在太阳轮齿轮顶部,其最大值为9.75×10^(-3)mm;行星齿轮减速器的模态结果主要表现为行星齿轮的扭转变形,其设计结果满足要求。
With the maturity and popularity of fiber laser applications,it has been widely used in automotive manufacturing,marine,medical and aerospace.In order to further improve the high reliability,stability and efficiency of fiber laser equipment,it is necessary to carry out finite element analysis and modal analysis of the planetary gear reducer.By establishing a simple model of the planetary gear reducer,taking the planetary gear reducer as the research object,analyzing the load and working conditions in the transmission process,using the three-dimensional software ANSYS to establish a three-dimensional model of the planetary gear reducer and importing the model into the finite element analysis software ANSYS Workbench,the three-dimensional model is subjected to a static finite element analysis and modal analysis.The experimental study shows that the equivalent stress and strain of the whole planetary gear reducer are mainly distributed in the meshing of the sun wheel and the three planetary gears,and the maximum stress occurs at the tooth root fillet of the sun wheel,with a maximum value of 119.64 MPa,the maximum strain occurs at the tooth root of the meshing gears,and the maximum displacement occurs at the top of the sun wheel gear,with a maximum value of 9.75×10-3 mm,the planetary gear reducer's modal results mainly show the torsional deformation of the planetary gear,and its design results meet the requirements.
