摘　　要：面向汽车变速器行业对高精度齿轮的需求,开发一种蜗杆和成型砂轮复合磨削的双工件主轴磨齿机床。该机床具备全自动更换刀具和全自动装卸被加工齿轮功能,可使用通用修整器同时修整蜗杆砂轮和成形砂轮;采用双工件主轴结构,节省了上下料装载时间,加工效率大幅提升,比单主轴效率高出30%左右;在合适的粗磨和精磨砂轮颗粒的作用下,蜗杆砂轮和成形砂轮磨削的结合使磨削时间减少了50%左右;自带齿轮检测设备,能够在线检测齿轮磨削加工量是否达到加工工艺要求,实现了齿轮磨削高效、高精度、节能环保加工。Aiming at the demand to high precision gear in automobile transmission industry, a dual-workpiece spindle grindingmachine tool combining forming grinding wheel with worm wheel was developed. The machine tool had automatic tool change and auto-matic loading/unloading machined gear functions. The worm wheel and the forming grinding wheel could be trimmed with a general pur-pose machine at the same time. The dual-workpiece spindle structure saved loading/unloading time, then the processing efficiency wasimproved greatly, higher than the single spindle efficiency about 30%. Under appropriate rough grinding and fine grinding wheel parti-cles, the combination of worm wheel and forming grinding wheel could greatly reduce the grinding time by about 50%. With gear tes-ting equipment, gear grinding quantity could be detected online to judge whether the processing requirements were met. So high effi-ciency, high precision, energy saving and environmental protection gear grinding processing is realized.
