根据一批低精度宽齿轮齿面啮合失准度F_(ma)的实测资料、统计计算出了系数K_(Hβ),K_(Hβ)≥2.2约占67.39％,这些数值远大于目前设计计算所采用的值。如果这一些齿轮的齿面硬化后,在评价其承载能力时,应该包括制造误差和材料的跑合性能。在本文中给出了一个实例,以资参考。对不同硬度、不同制造误差下齿面硬化的相对效果,作出了大致的数值比较。 According to the measured data of the misalignment degree F_ (ma) of a series of low precision wide gear tooth surfaces, the coefficients K_ (Hβ) and K_ (Hβ) ≥2.2 are estimated to be 67.39%, which are much larger than the current design calculation The value used. If some of these gears have flanks that harden, evaluation of their load carrying capacity should include manufacturing errors and material run-out behavior. In this paper, an example is given for reference. For different hardness, different manufacturing error under the tooth surface hardening relative effects, made a rough numerical comparison.
