A hydraulic driving system for bidirectional plow rake cutting coulter tooth roll belongs to an assembly on the agricultural implement of plows and soil tillage. 双向耕耙犁刀齿辊液力驱动机构属于耕整地农具上的一个总成。
There is a special way of design of carbon alloy slotting tool which has minus rake angle to increase the ability of resisting the tooth edge collapse. 为提高硬质合金插齿刀的抗崩刃能力,需要采用负前角的特殊设计;
Influence of Front Rake of the Slotting Cutter on the Tool Endurance and Tooth Profile Error 插齿刀前角对刀具耐用度及齿形误差的影响
As the carbide gear hob with negative rake angle is of the curve edge, it is more complicated and difficult to increase the accuracy life of the tooth profile of this kind of hob than that of the standard gear hob with straight edge. 负前角硬质合金齿轮滚刀具有曲线刀刃,提高其齿形精度保持性比具有直线刀刃的普通齿轮滚刀更复杂、更困难。
