目前大部分工厂都采用刨齿机加工直齿圆锥齿轮。由于刨齿过程的不连续切削,以及刨齿机本身刚性不足等原因,加工出来的齿轮齿面光洁度一般都较差。我们采用了以下几点措施,使齿面光洁度能达到▽▽6以上。1.加工45钢和40Cr钢的齿轮时,毛坯按一般正火温度加热,然后在水中冷却几秒,硬度控制在H_B=200～220之间。这样加工出的齿面光洁度比经调质处理的要好。2.装卡时,应尽量使基准端面与心轴支撑端面
At present, most factories use gear shaper to machine straight bevel gear. Due to the discontinuous cutting of the tooth cutting process and the lack of rigidity of the gear cutting machine itself, the finished gear tooth surface finish is generally poor. We have adopted the following measures to make the tooth surface finish up to ▽ ▽ 6 or more. 1. For 45 and 40Cr steel gears, the blank is heated at normal normalizing temperature and then cooled in water for a few seconds with a hardness controlled between H_B = 200 and 220. This processed tooth surface finish than quenched and tempered better. 2. Card loading, should try to make the reference end and spindle support end
