摘　　要：为了满足航空传动的紧凑空间设计要求,研究一种新型点接触斜线齿面齿轮及其齿宽设计。根据渐开线插齿刀方程,模拟插齿刀与工件的运动关系,推导斜线齿面齿轮的齿面方程;建立内端根切、外端变尖、限定工作齿高和避免二次切削等限制条件,计算面齿轮的有效齿宽。分析倾斜角、交点位置对内径、外径及齿宽的影响。研究结果表明:减小刀顶圆角半径可避免齿根发生二次切削;增大倾斜角和交点位置的增量,面齿轮的内径和外径都增大,而有效齿宽却减小。In order to satisfy the need of compacted design of transmission system in aviation application, a new point-contacted face gear with tilted tooth trace and the design of tooth width were studied. The equations of shaper were derived and the generated relationship between sharper cutter and work piece was simulated, and the tooth surface of face gear can be established. By setting the limiting conditions like undercutting on root of the toe, pointing on addendum of the heel, giving depth on tooth working surface and avoiding the second cutting on the toe, the valid tooth width was determined. The influence of the titled angle and positions of cross point on the inner and outer radius and tooth width were investigated. The results show that the radius of top rounder mostly affects the second undercutting of tooth root. With the increasing of the tilted angle or moving of the crossing point from the toe to the heel, the inner and outer radii increase, while tooth width decreases.
