关键参数对滚子包络内啮合蜗杆传动接触与润滑性能的影响

为了分析关键参数对滚子包络内啮合蜗杆传动接触与润滑性能的影响,构建了该新型蜗杆传动的数学模型,通过啮合方程构建了该传动的润滑角与诱导法曲率方程,利用数值计算方法分析了中心距、传动比、蜗轮偏转角、滚子半径等关键参数对蜗杆传动润滑与接触性能的影响。分析研究得知,在这些关键参数中,蜗轮偏转角对滚子包络内啮合蜗杆传动的接触性能与润滑性能有较大的影响,建议蜗轮偏转角取值在0°～40°为最佳。选取了相应参数进行三维建模,验证了分析参数的有效性。该研究为滚子包络内啮合蜗杆传动的进一步研究提供了参考。

Influence of Key Parameter on Contact and Lubrication Performance of the Roller Enveloping Internal Engagement Worm Gear Transmission

In order to analyze the influence of key parameters on the contact and lubrication performance of the inner meshing worm gear of the roller envelop,the mathematical model of the new worm drive is built.And the lubrication angle and the induced normal curvature equation are constructed by the meshing equation.Then the influence of the key parameters on the lubrication and contact performance of worm drive are analyzed by the numerical calculation method.These key parameters include the center distance,the transmission ratio,roller radius and the worm-wheel rotational deflection.The analysis shows that in these key parameters,the de.flection angle of the worm wheel has a great influence on the contact and lubrication performance of the inner meshing worm gearing of the roller envelope.It is suggested that the deviation angle of the worm wheel is the best in the range of 0°to 40°.And the corresponding parameters are selected for 3D modeling analysis to verify the validity of the analysis parameters.The study provides a reference for further research on the roller envelop.ing internal worm drive.
