日本工业技术院名古屋工业技术试验所研制成新的齿轮滚轧方法及装置。该方法是在圆筒中安装数层有几个齿的轧辊,将原料压入圆筒内,使其通过轧辊成齿轮。其关键是圆筒和圆筒中的轧辊,特别是轧辊设计。它是把一个 Japan Industrial Technology Institute Nagoya Industrial Technology Test Institute developed a new gear rolling method and device. The method is to install a few rollers in the cylinder with several teeth, the material is pressed into the cylinder, through the roll into the gear. The key is the cylinder and cylinder roll, especially the roll design. It is to put one
