大模数蜗轮是重要产品之一,原设计蜗轮轮(?)用青铜浇铸,但需用铜10吨,而且要10万元基建投资,2年试浇及生产时期,大型青铜铸件的质量又难保证。怎么办?毛主席的教导“要节约闹革命。”,“备战、备荒,为人民。”,使人们开了窍,决定在钢基上用青铜堆焊齿面。这样既快、又好,而且省,为工程建设争时间,立足于打,立足于早打。在钢件上堆焊铜使强度大大高于原铸件。用铜重只需200公斤,只有原设计的五十分之一。蜗轮直径≈2000毫米,蜗轮齿数46只。
Large modulus worm gear is one of the important products, the original design worm wheel (?) Cast with bronze, but need 10 tons of copper, but also to 100,000 yuan investment in infrastructure, 2 years trial pouring and production period, the quality of large bronze cast Difficult to guarantee. How to do? Chairman Mao’s teachings “To save the trouble revolution.” “Preparing for war, preparing for the poor, for the people.” People opened the orifices, decided to use steel on the steel base welding tooth surface. This is fast and good, and the province, for the construction of the struggle for time, based on the fight, based on the early fight. Copper brazing on steel makes the strength much higher than the original castings. With copper weighs only 200 kilograms, only one-fiftieth of the original design. Worm diameter ≈ 2000 mm, 46 worm gear teeth.
