该系列齿轮箱设计起点高，加工精度高，箱体采用高性能球墨铸铁材料，提高了减震性能，经二次热处理时效，极大地降低了变形量，全部采用加工中心精加工，从而保证了各种精度要求。箱体进行了强度优化设计，使各部位的尺寸更加合理，箱体的强度得到了很大的提高。
This series of tanks are based on top design and high precision process. The tanks are made of nodular cast iron of high quality, enhancing its ability of shock absorption while reducing its transformation capacity greatly by reheat treatment. The tanks are optimized for their intensity and sizes of all parts by reasonable design, as a result of which the intensity of tanks are greatly enhanced. Meanwhile, by processing whole products in our process center, all requirements on precision are met completely.
