摘要
为了研究RV减速器在额定载荷作用下的应力和变形情况,应用ANSYS软件对RV-40E型减速器的主要传动机构——摆线针轮机构和偏心轴机构进行分析。分析结果表明,在额定载荷作用下,摆线针轮机构与偏心轴机构的最大接触应力和最大等效应力均小于所用材料的强度极限。由于受力导致相配合的零件间产生间隙,会降低RV减速器的传动精度,因此在设计、制造RV减速器时需重点关注弹性变形对传动精度的影响。偏心轴的扭转变形较大,刚度较低,对RV减速器的传动精度影响较大,因此在设计、制造RV减速器时需选择合理的材料和工艺,提高偏心轴刚度,进而提高RV减速器的传动精度。
In order to study the stress and deformation of RV reducer under rated load,ANSYS software was used to analyze the main transmission mechanism-the cycloid pinwheel mechanism and eccentric shaft mechanism of RV-40E reducer.The results show that the maximum contact stress and the maximum equivalent stress of the cycloidal pinwheel mechanism and the eccentric shaft mechanism are less than the strength limit of the used material under the rated load.Because of the clearance between matching parts caused by force,the transmission accuracy of RV reducer would be reduced.Therefore,the influence of elastic deformation on transmission accuracy should be paid more attention in the design and manufacture of RV reducer.The larger torsional deformation and lower stiffness of the eccentric shaft have a relatively worse impact on the transmission accuracy of RV reducer.Therefore,it is necessary to select reasonable materials and processes to increase the stiffness of the eccentric shaft and further improve the transmission accuracy of the RV reducer in designing and manufacturing the RV reducer.
