我们为Y3180滚齿机设计了加工小直径齿轮的装置,将该装置安装在滚齿机上,调整后就能加工分庭圆为10mm的齿轮,扩大了机床的加工范围。装置结构简单、装卸方便,经多年使用,性能良好。结构如图所示。在原滚齿机工作台的锥孔中装上芯轴12,轴上套有齿轮8。齿轮7安装在主轴3上。主轴装在支架5的滑动轴承4和6中,支架用螺栓15和压条16固定在机床外支架的导轨上。工件芯轴20
We designed a Y3180 gear hobbing machine for machining small diameter gears. The unit was mounted on a gear hobbing machine and a 10mm round gear was machined to broaden the machining range of the machine. Device structure is simple, easy handling, after years of use, good performance. Structure as shown. In the original hobbing machine table taper hole mounted mandrel 12, the shaft sleeve gear 8. Gear 7 is mounted on the spindle 3. The spindle is mounted in the plain bearings 4 and 6 of the carriage 5, which are fastened to the guide rails of the outer support of the machine with bolts 15 and beads 16. Workpiece mandrel 20
