driven roll

Precise Driven of Zero-drive Work-shaft in CNC Gear Hobbing Machine;

数控滚齿机中“零传动”工件轴的精确从动

The results show that shrinking inner hole of driven gears is conducted by heating with protective atmosphere and cooling in the iron tube-shaped container for slowly cooling gears,the exceeded tolerance problem of inner hole of driven gears can be better solved,and 90% driven gears can meet the needs of technology reguirement of the production.

通过两种工艺试验证明,采用保护气氛加热入缓冷筒冷却进行收缩齿轮内孔的方法,较好地解决了从动齿轮因孔大超差报废问题,使90%的齿轮达到了产品技术要求。

Effect of superfine Ni powder addition on the sintering process and final properties of driven gears was studied.

研究了经超细化处理的镍粉对从动齿轮烧结工艺和性能的影响。

Driven gear cracking was found in repair.
