回转支承套圈整形机架刚度及动力学分析

Stiffness and Dynamics Analysisof Reshaping Frame of Ferrule of a Slewing Bearing

回转支承套圈整形设备由回转支承定位机构、支承柱旋转机构、电涡流传感器定位机构、滑动机架定位机构以及助动筒辅助支撑机构这五大机构组成。利用此设备进行回转套圈整形时,回转支承套圈变形时产生的作用于压板上的变形力较大。针对回转支承套圈整形机架变形大的问题,利用ANSYS workbench对机架结构进行静刚度分析,确定其机械结构的最佳设计方案,并对所设计的机架结构进行模态分析,研究其振动特性以避免工作时发生共振对设备整形精度产生影响。

The proposed equipment is composed of a slewing bearing locating mechanism, a ferrule rotating mechanism, an electrical vortex sensor locating mechanism, a sliding frame locating mechanism and a power-assisted cylinder mechanism. The force applied on the plate by the slewing bearing ferrule is comparatively large when this equipment is used to reform. In order to solve the deformation about the reshaping frame of ferrule of a slewing bearing, this paper used ANSYS workbench to analyze the static stiffness of the reshaping frame. The optimal design scheme about the mechanical structure of lhe reshaping frame was determined. Finally the modal analysis of the resilaping frame was studied to avoid resonance.
