摘要: 给出了高重合度弧齿锥齿轮的加工参数设计方法。利用局部综合法、轮齿接触分析(TCA)、轮齿承载接触分析(LTCA)和啮合仿真技术,通过齿面接触路径倾斜,达到了高重合度的设计目的。该设计方法不改变轮坯的几何参数,不改变大轮的加工调整参数,可在现有的机床上使用标准系列刀具加工,实用性强。给出了三种齿面接触路径倾斜度不同的设计方案,进行了啮合仿真分析与重合度测定,结果证明,用该方法可设计出重合度达2.0~3.0的高重合度弧齿锥齿轮。

Abstract: The design method of machine-tool settings is proposed on the spiral bevel gears with high contact ratio. Basing on the local synthesis method, TCA and LTCA techniques, a high contact ratio can obtained by enlarging the bias angle of contact path at the tooth surface. The method needn’t modify the geometrical parameters of the gears set and the gear machine-tool settings. The designed gears set may be cut by the present machine-tools and the standard serial cutter. The three designs of different contact paths are presented, the mesh simulation analysis are carried on and the contact ratio are tested. This results demonstrated that these method and theory can be design the spiral bevel of contact ratio reaching to 2.0~3.0.

Key words: Contact ratio, Machine-tools settings, Spiral bevel gears, TCA
