Research on installation and detection technology of spherical plain bearings

Spherical plain bearings play an important role in aircraft control systems because of their excellent load-carrying capacity. However, the difficulties in controlling the installation process and detecting the installation effect have been the key issues limiting the product yield. According to the problems of low installation efficiency and poor quality consistency that exist in the traditional punching point installation method, this study analyzes the key installation process of bearings and summarizes the two major factors, the punching point position and the punching point depth, affecting the installation quality of bearings. A six-point punching point installation tool with a punching point depth/position control structure is designed to greatly improve the installation quality and efficiency of bearing installation. For evaluating the installation effect of bearings, this paper develops a kind of spherical plain bearing starting torque automatic detection equipment with the dual drive system, which adds the oscillating torque measurement function in addition to the rotating torque detection function and realizes the automated and comprehensive detection of the starting torque of bearings with a single clamping.
