在成批、大量的生产条件下制定齿轮制造工艺时必须考虑的主要问题是:节约金属材料,提高产品质量和生产率,减少劳动量,使工人从繁重的劳动中解脱出来等等。只有采用一系列新的工艺措施才能解决这些问题。包括楔形横轧阶梯轴,冷热模锻,在多位自动机上热镦,粉末冶金,热轧和热模锻带齿的毛坯等等。由镍铬钢和铬钼钢制造的齿坯应进行等温退火获得均匀的金属组织和好良的切削性能,
The main issues that must be considered when formulating a gear manufacturing process under batch, mass production conditions are: saving metal materials, improving product quality and productivity, reducing labor costs, freeing workers from heavy work, and so on. Only a series of new technological measures can solve these problems. Including wedge-shaped cross-rolling ladder shaft, hot and cold forging, in a number of automatic machine upsetting, powder metallurgy, hot-rolled and hot forged with the tooth blank and so on. Gear blanks made of nickel-chromium steel and chromium-molybdenum steel should be isothermal annealed to obtain uniform metallic structure and good machinability,
