摘要
不对称齿型的双螺杆转子可能出现负力矩。决定负力矩大小的主要因素是齿槽接触线两侧的投影面积之差。建议将这个面积定义为负力矩面积，以便与接触线长度、泄漏三角形、有效容积等具有同等意义，作为评定齿型特性的几何因素。
The phenomennon of countrary torque occurs on the driven rotor for the unsymetric profile screw compressors. The primary factor determining this torque is the area difference between the front and back groove surfaces devided by the meshing line. It is proposed to define this area difference as the countrary torque area. Just as other charateristic values, contact-line length, leakage triangle and effective volumn ratio, this area can be used as a discriminatory criterion, assessing the geometric property of the screw profile.
