直线-共轭线型内啮合齿轮泵齿廓分析

Tooth Profiles Analysis for Internal Pump Gear with Straight Line-Conjugate Curve Profile

针对直线 -共轭线型内啮合齿轮泵 (NB泵 )中 ,与直线齿廓小齿轮啮合的内齿环的齿廓问题 ,根据“齿廓啮合定理” ,用“齿廓法线法”导出了计算公式 ,给出了公式的取值范围 ,并由应用实例验证了公式的正确性。

Based on Willis theory, the tooth profile of the ring gear used in the NB pump is obtaind and the calculation formula is presented. It is approved by an example.
