摘要

人字齿轮传动由于加工安装误差、轴承支撑布置无法对称等条件，不可避免会产生轴线的微量不平行。因人字齿轮齿宽较大、啮合刚度高、标准渐开线齿面线接触等特点，微量的轴线不平行度就会导致严重的齿面偏载，影响齿轮传动的平稳性和可靠性。因此，采用了小轮较大轴向浮动的轴承支撑结构，并研究了小轮轴向浮动的人字齿轮齿面承载接触仿真（LTCA）方法，通过大、小轮轴向固定和小轮轴向浮动两种不同轴承支撑结构的仿真比较，说明小轮轴向自位浮动可以有效改善齿面偏载，为人字齿轮传动系统的设计提供了参考。

Abstract

Due to the machining and installation errors of herringbone gear transmission， the unsymmetrical arrangement of bearings and so on， it is inevitable that tiny axis non-parallelism will appear in gear transmission system. Herringbone gears have the characteristics of large tooth width， great meshing stiffness and line contact for standard involute tooth surface. However， the tiny axis non-parallelism will lead to serious eccentric load on tooth surface， and eccentric load affects the stability and reliability of gear transmission. Therefore， a bearing support structure with a great axial floating pinion is adopted， and loaded tooth contact analysis （LTCA） method for the herringbone gear system with the axial floating pinion is studied. Through the simulation comparison on two different bearing support structures， it is shown that the bearing support structure with the axial floating pinion can effectively decrease the eccentric load on the tooth surface. The conclusion provides a reference for the design of herringbone gear transmission systems.
