摘　　要：为降低抽油机运行维护成本,对抽油机减速器进行再制造,针对减速器中磨损的双圆弧齿轮进行修复。在已有研究的基础上,提出一种基于逆向工程提取齿轮设计参数并对齿轮磨损程度进行分析的方法。使用三维激光扫描技术提取磨损齿轮模型数据,在Geomagic Design X软件中处理齿轮模型,运用面片草图拟合的方法测量齿轮模数,推导出分度圆螺旋角。使用双圆弧轮齿端面齿廓方程,建立双圆弧齿轮精确实体模型。对实际工程中的双圆弧齿轮轴参数进行提取和偏差分析,通过Geomagic Control X将双圆弧齿轮三维模型与扫描模型对齐后分析偏差。结果表明:与手工测量相比,所提方法在保证测量精度的同时降低了测量难度,提高了齿轮测量的效率。In order to reduce the operation and maintenance cost of the pump,the pump reducer was remanufactured,and the worn double arc gear in the reducer was repaired.On the basis of the existing research,a method based on reverse engineering to extract gear parameters and analyze the gear wear degree was proposed.The 3 D laser scanning technology was used to extract the worn gear model data,the gear model was processed in Geomagic Design X software,and the gear module was measured by using the mesh sketch fitting method,and the index circle helix angle parameter was derived.By using a double arc face gear tooth profile equation,the double circular arc gears accurate model was established.The actual engineering double-arc gear shaft parameter extraction and deviation analysis were carried out,and the deviation was analyzed after the solid model was aligned with the scanning model through Geomagic Control X.The results show that compared with manual measurement,by using the proposed method,the measurement difficulty can be reduced while ensuring the measurement accuracy,and the efficiency of the gear measurement can be improved.
