摘要:
为预控双重螺旋法加工的螺旋锥齿轮的啮合性能,研究基于Ease-off的螺旋锥齿轮齿面修形方法。用大轮理论齿面展成得到小轮共轭齿面,基于预设的对称抛物线传动误差和接触迹,将齿面划分为小端、中间接触区、大端共3个区域,并基于局部共轭原理沿啮合线方向对3个区域进行3段抛物线修形,得到目标齿面;采用Ease-off齿面接触分析方法,对得到的目标齿面啮合性能进行分析。研究结果表明:传动误差的形状、幅值、接触迹线与接触印痕达到预置要求;分区修形方法为双重螺旋法加工的齿轮工作齿面、非工作齿面同步分区修形优化提供了新途径。
摘要(英文):
A novel ease-off flank zoning modification method was proposed to pro-control the meshing performance of spiral bevel gears manufactured by duplex helical method. The conjugate pinion tooth surface was modified to meet the preconditions, which was generated by gear theoretical tooth surface, and then the conjugate pinion tooth surface was divided into three regions, i.e., the toe, the middle and the heel. These regions' modification with three segment parabolics were conducted along the contact path and the contact line. Ease-off tooth contact analysis methodology was used to analyze the target tooth surface meshing performance. The results show that the transmission error, contact path and contact line are the same as the pre-preconditions. The novel zoning modification method can be used for modification research of whole tooth surface of spiral bevel gears manufactured by duplex helical method.<br/> &copy;2018, Central South University Press.
