摘　　要：提出一种新的键槽拉刀,即凸圆弧齿键槽拉刀,并将其与现行技术中的直齿键槽拉刀和斜齿键槽拉刀进行对比。经分析认为,凸圆弧齿键槽拉刀比其它键槽拉刀更具有优越性。This paper presents a new keyway broach which is a convex circular arc tooth keyway broach. Straight tooth keyway broach and helical tooth keyway broach is the current technology. The paper makes a comparative analysis on straight tooth keyway broach, helical tooth keyway broach and convex circular arc tooth keyway broach. Finally the study concluded that the convex circular arc tooth keyway broach has more advantages than other keyway broach.
