渐开线内啮合有一些公认的有利特性,它在圆柱齿轮中占有特殊的地位。因为它是凸齿面与凹齿面相接触,因此内啮合的齿面承载能力比外啮合齿面大大提高,此外当功率相同时,内啮合齿轮传动的中心距和外廓尺寸较小,并因滑动较小,其磨损也小于外啮合齿轮传动。内啮合的缺点是制造上磨齿困难。如果机加工以后不进行热处理,则在工艺上的困难部分地可通过剃齿来加以解决。
Involute internal engagement has some well-recognized favorable characteristics, it occupies a special position in the cylindrical gear. Because it is convex tooth surface and concave tooth surface contact, so the internal gear tooth surface carrying capacity greatly increased compared with the external gear, in addition, when the power is the same, the internal gear transmission center distance and outline size smaller, and due to Slippage is small, the wear is less than the external gear transmission. The disadvantage of internal meshing is the difficulty in manufacturing the upper gear. If the machining is not carried out after the heat treatment, then the process of difficulty can be partially solved by shaving.
