一种立方抛物线-圆弧齿轮
摘要：
本实用新型公开了一种立方抛物线-圆弧齿轮，所述齿轮在法截面的齿廓为立方抛物线齿廓；所述齿轮的齿顶和齿根均为圆弧形；所述齿轮的啮合为凹凸齿面啮合，使齿轮传动平稳，噪音小，寿命长且传动效率高。
摘要（英）：

The utility model discloses a cubic parabola circular tooth gear. The tooth profile of the gear on the normal section is the tooth profile of a cubic parabola; the tooth crest and the tooth root of the gear are both in a circular arc shape; and the gear is in concave-convex tooth surface engagement, so that the gear is stable in transmission, low in noise, long in service life and high in transmission efficiency.
