Research of Bump Detection Method of Spiral Bevel Gear Tooth Surface based on Gear Contact Analysis

提出一种齿轮副齿面磕碰点检测方法,用于确定弧齿锥齿轮齿面磕碰点位置。建立准双曲面齿轮副啮合模型,通过改变接触区偏移量,调整啮合参数V、H、J,从而得到规划路径下的TCA接触区位置,V、H、J调整结果用于指导滚检试验。在YX-HTT600齿轮综合误差测量及分析试验机上进行滚检试验,得到了准双曲面齿轮副正常齿面与存在磕碰点的齿面两种情况下的传动误差测量结果。通过对两种传动误差测量结果的对比,验证了提出的齿面点测量方法的可行性。试验结果表明,运用提出的齿面检测方法可实现弧齿锥齿轮全齿面检测,检测结果可反映齿面磕碰点位置,从而为进一步改善弧齿锥齿轮啮合性能奠定基础。

A detection method of gear tooth flank bump is presented,which is used to determine the position of bump surface of spiral bevel gear.A meshing model of hypoid gear pair is established,and the V,H,J adjustment is solved by changing the offset of the contact zone to obtain the position of the TCA contact zone under the planned path.The V,H,J calculation result is used to guide the rolling inspection experiment.In YX-HTT600 gear error measurement and analysis of comprehensive testing machine rolling test,the transmission error measurement results of the two cases of hypoid gear pair normal tooth surface and the existence of bump tooth surface are got.By comparing the measurement results of the two kinds of transmission errors,the feasibility of the proposed tooth surface measurement method is verified.The experimental results show that the proposed tooth surface detection method can be used to detect the entire tooth surface of spiral bevel gears.The test results can reflect the position of the bump surface and the number of the tooth surface with bumping points,which can lay a foundation for further improving the meshing performance of the spiral bevel gear basis.
