    摘要:

    為查明三環(huán)減速器應(yīng)用中出現(xiàn)振動(dòng)大、行星軸承燒蝕等問(wèn)題,借助ANSYS有限元軟件建立了三環(huán)減速器傳動(dòng)部分的有限元分析模型。利用ANSYS中的自由度耦合和固定約束,將系統(tǒng)中各零部件間的非線性接觸問(wèn)題簡(jiǎn)化為線性問(wèn)題加以分析。通過(guò)對(duì)三環(huán)減速器有限元模型的求解,分析了系統(tǒng)各環(huán)節(jié)的受力,計(jì)算了齒輪嚙合力、支撐軸承力、輸出轉(zhuǎn)矩和內(nèi)齒板的應(yīng)力。將有限元計(jì)算的結(jié)果與實(shí)驗(yàn)數(shù)據(jù)作了比較,二者吻合較好,表明有限元分析模型具有較高的精度。

    Abstract:

    A finite element model for a three-ring gear reducer was established to analyze the reasons of the heavy vibration and the bearing fatigue appeared during operation by using ANSYS. The complicated non-linear contact problem in each reducer part is simplified into a linear problem with the concept of degree of freedom coupling and restriction. By solving the finite element model, the reactions on internal gears and bearings were obtained. The experimental results indicate that the finite element analysis has a satisfactory accuracy.
