应用齿顶整圆弧滚刀是提高齿轮弯曲疲劳强度的有效措施之一。

Full radius hob on tooth tip is one of the effective measures by increasing gear tooth bending strength.

在机构强度分析中，阐述了凸轮-针轮副啮合齿面接触强度、针齿销的弯曲强度计算和刚度计算。

Not only the contact strength between the CAM and the rollers is discussed, the flexural strength and rigidity of the rollers are also discussed.

然后对设计出 来的转向器进行强度校核，主要是钢珠与滚道的接触应力、齿扇的弯曲应力和摇 臂轴直径的确定。

Then out of the steering of the design strength check, mainly steel ball and the raceway contact stress, bending stress and tooth fan rocker shaft diameter determined.
