摘　　要：齿轮是现代工业及制造业中的关键零部件之一,为适应齿轮大批量生产及质量控制与检测需求,研制了一种基于激光扫描技术的齿轮参数测量系统,系统刚度是保证齿轮参数激光测量系统精度的重要因素之一。在Solidworks与ANSYS Workbench的集成研发平台下,分别对齿轮参数激光测量系统的两种极限工况作了有限元静态分析,认为应力集中是造成系统刚度不足的主要原因。通过采用平衡配重的方法,改变系统的应力分布,从而提高系统刚度。仿真试验表明:改进后该测量系统的激光测头处的总变形量减小至1.92μm,与改进前相比降低了57%,满足设计指标(3μm)要求,同时系统刚度得到了有效改善。Gear is one of the key components in modern industrial and manufacturing,and in order to adapt to the gear mass production,quality control and testing requirements,it developes a kind of gear parameter measurement system based on laser scanning technology,The system stiffness is one of the most important factors on the accuracy of gear parameter laser measurement system.In the integrated research and development platform of Solidworks and ANSYS Workbench,the tension of gear parameters laser measurement system under two extreme static working conditions were analyzed respectively.Stress concentration is considered to be the main reason that causes the stiffness insufficient of the system.By adopting the method of balanced counterweight,stress distribution of the system changed and the stiffness of testing system was improved.The result of the simulation test shows that the system meets the requirements of design accuracy 3μm and the stiffness of the system proves to be apparently improved.Since the total deformation at the laser probe reduced to 1.92μm after improvement,which reduced 57% compared with the original system.
