为了提高弹性支承条件下中央弧齿锥齿轮的工作可靠性，首先应保证其接触的稳定性。本文针对某航空发动机转子，计算了在转子不平衡量和齿轮啮合力同时作用下，弧齿锥齿轮支承处的变形大小；依据支承变形对齿轮接触特性的影响机理，将变形转化为齿轮安装调整值ΔＨ、ΔＪ和ΔＶ；利用空间啮合理论，建立了弧齿锥齿轮传动的接触稳定性条件以及接触特性分析方法。分析计算了不同转速和不同功率下弧齿锥齿轮的齿面接触印痕和传动曲线，研究了转子共振时齿轮接触的失稳现象，获得了提高弹性支承条件下中央弧齿锥齿轧传动的接触稳定性的措施。
In order to improve the working reliability of the central spiral bevel gear under elastic support conditions, first of all, the stability of its contact should be guaranteed. In this paper, for aeroengine rotor, the deformation of the bevel gear supported by the unbalanced rotor and the gear meshing force is calculated. Based on the mechanism of bearing deformation on the contact characteristics of the gear, the deformation is converted into gear installation adjustment value ΔH, ΔJ and ΔV. According to the theory of space meshing, the contact stability conditions and contact characteristics of spiral bevel gears were established. The contact print and transmission curve of the spiral bevel gear with different rotation speed and power are analyzed and calculated. The instability of the contact of the gear during resonance of the rotor is studied. The contact of the central spiral bevel gear with the elastic support is improved Stability measures.
