渐开线KHV传动只需一对内啮合齿轮,具有体积小重量轻,加工零件少等优点。但由于内外齿轮的齿数相差很少,容易发生干涉,需采用较大啮合角,而对受力和效率均为不利。故一般文献认为KHV传动效率较低,并且速比大时更低,因此只能用于小功率传动。作者使用合理的内啮合几何尺寸计算方法、较精确的啮合效率公式、和优化技术,设计了通用程序,计算过400余题,取得了较好的参数。所需的啮合角比一般文献要小10°,啮合效率大于92%,并且速比大时效率并不降低。由此得出结论:KHV传动能够获得较高效率,可以用于中等功率和大适比传动。为KHV传动的进一步发展提供了方向。
Involute KHV transmission only a pair of internal gear, with small size and light weight, fewer processing advantages. However, due to the small difference between the number of teeth inside and outside the gear, prone to interference, the need to use a larger engagement angle, while the force and efficiency are negative. Therefore, the general literature that KHV transmission efficiency is low, and low speed ratio larger, it can only be used for low-power transmission. The author has designed more than 400 questions and obtained the better parameters by using a reasonable calculation method of internal geometry, accurate meshing efficiency formula and optimization technique. The required engagement angle is 10 ° smaller than that of the general literature, the engagement efficiency is greater than 92%, and the efficiency does not decrease when the speed ratio is large. This concludes that: KHV transmission can achieve higher efficiency, can be used for medium-power and large than the appropriate drive. KHV transmission for the further development of the direction.
