本文在GB3480-88 K_(Hβ)一般方法的前提下,不改变其计算方法的内容,但对计算形武加以演化与提炼,提出K_(Hβ)的速算法。速算法适用于直齿、斜齿和人字齿。考虑了齿向修形的三种形式的影响:考虑了各种工艺条件下制造误差的补偿。适用于各种齿面硬度、精度5至9级、载荷轻的和重的齿轮传动。结构形式为简支或悬臂。所以速算法适用范围几乎与一般方法相同。速算法没有对一般方法做实质性的假设简化,从根本上克服了简化方法限制条件太多,误差较大的缺点。但依靠图表,简化了计算手续,有简便迅速的优点。速算法将K_(Hβ)的各组成部分清晰地区分开,便于分析比较,有助于设计者寻找改善K_(Hβ)的合理途径。本文介绍的速算法,更有理由成为K_(Hβ)计算的简便方法。
Under the premise of the general method of GB3480-88 K_ (Hβ), this paper does not change the content of its calculation method. The speed algorithm applies to straight teeth, helical teeth and herringbone teeth. The effects of the three forms of tooth modification are considered: compensation for manufacturing error under various process conditions is taken into account. Suitable for all kinds of tooth surface hardness, accuracy of 5 to 9, light and heavy load gear. Structure is simple or cantilever. Therefore, the application of the speed algorithm is almost the same as the general method. The fast algorithm does not simplify the general assumptions of the general method, and fundamentally overcomes the shortcomings that the simplified method has too many restrictive conditions and large error. But rely on the chart, simplifying the calculation procedures, there is the advantage of simple and rapid. The fast algorithm clearly separates the components of K_ (Hβ), which makes it easier for analysis and comparison to help designers find a reasonable way to improve K_ (Hβ). The speed algorithm introduced in this paper is more reasonable to be a convenient way to calculate K_ (Hβ).
