基于双螺杆压缩机齿间间隙的生成原理, 提出将 阳转子齿面沿接触线的法向间隙作为 阳转子
的齿间间隙, 将螺杆压缩机齿间间隙分布的计算转化为沿接触线的间隙分布的计算, 即转化为沿接触线的间
隙带的计算. 计算结果表明, 螺杆压缩机齿间间隙分布存在跃升现象. 该方法可以获得完整的齿间间隙分布
规律, 可以量化不同的齿间间隙获得方法对齿间间隙分布的影响, 计算精度能够满足工程设计的需要.

Abstract Based on producing principle of the interlobe clearance of twinscrew compressor, a mathematical algorithm
is presented, where the normal distance betw een the two screw rotor surfaces along the contact line is considered as the
interlobe clearance. Therefore the calculation of interlobe clearance is transformed to the calculation of clearance distri
bution along the contact line. The results show that clearance jump exists along the contact line, and the total interlobe
clearance distribution can be obtained with higher accuracy via the proposed algorithm.
