摘　　要：钢球表面缺陷对轴承的使用性能具有很大影响,针对目前钢球表面缺陷自动检测中球面全表面展开的问题,提出一种球面螺旋线运动展开方法,通过理论分析,建立了球体螺旋线运动展开模型,并提出了球面全表面展开的条件;依据展开条件,设计了球面全表面螺旋线展开机构,并对机构进行了运动特性分析;同时利用ADAMS软件,对机构进行运动学仿真,结果证明:本文所设计的展开机构能够实现钢球的全表面展开,进而为实现钢球全表面缺陷自动检测打下理论基础.The steel-ball surface detects have a great impact on the functional performance of the bearing. In this paper, for the question of spherical whole surface unfolding in automatic detection of the steel-ball surface de- fects, we have presented a kind of spiral line unfolding mechanism. According to the theoretical analysis, we have established the model on spiral line unfolding movement of sphere and proposed the whole surface unfolding condi- tions of sphere, based on which we designed a type of corresponding mechanism and analysed its mechanical dy- namics. In addition, we carried out the kinematics simulation to this mechanism by the ADAMS software. The re- sult proved that the steel ball can be completely unfolded by the mechanism designed in this paper, which laid a theoretical foundation for the steel-ball whole surface unfolding in the automatic detection.
