大齿圈是287/470型球磨机的关键性另件,是我厂主要产品之一。它的外径有4.4公尺(图1),而我厂现有的最大滾齿机床为F0-25捷克滾齿机,它的工作台只有三公尺,所以没法加工。在这次大闹技术革命,大搞简易设备的群众运动中,技术人员和工人相结合,制造出数以百计的简易设备,用“从土代洋,土洋结合”、“化大为小、从小干大”的办法解决了许多生产关键问题,大齿圈的加工也成功地解决了。现将我们目前加工大齿圈的两种方法简单地介绍出来,以供大家参考。 Large ring gear is 287/470 type ball mill key pieces, is one of our main products. Its outer diameter of 4.4 meters (Figure 1), and I plant the largest hobbing machine F0-25 Czech hobbing machine, its table is only three meters, it can not be processed. In this massacre of technological revolution, the masses engaged in mass production of simple equipment, the combination of technicians and workers created hundreds of simple equipment and used “ Small, big stem ”approach to solve many of the key production problems, the ring gear processing has also been successfully resolved. Now we are currently processing two large ring gear method simply introduced for your reference.
