螺杆式压缩机
摘要：
一种螺杆式压缩机(1)，包括：分别绕第一转动轴线(O1)和第二转动轴线(O2)转动的阳转子(2)和阴转子(3)，所述转子(2、3)在剖面上示出啮合的凸部(4)和凹部(6)，且具有通过包络刨齿刀型面(p)而产生的型面，其中，所述刨齿刀型面(p)包括：所述刨齿刀型面(p)的第一曲线(z1)，该第一曲线(z1)在笛卡尔坐标系(X，Y)中的第一点(H)与第二点(Q)之间延伸且具有沿横坐标轴(X)正向的凸度，所述第一点(H)位于横坐标轴(X)上，距笛卡尔坐标系(X，Y)的原点(O)的距离等于阳转子(2)的齿顶高(h1)。
摘要（英）：

A screw compressor (1) comprising: a male (2) and a female rotor (3) rotating respectively around a first axis (01) and second axis (02) of rotation, said rotors (2; 3) showing, in cross section, meshing lobes (4) and valleys (6) and having profiles generated by enveloping a rack profile (p) including a first curve (z1) of the rack profile (p) extending between a first point (H) and a second point (Q) in a Cartesian reference frame (X, Y) and having a convexity in the positive direction of the axis of abscissa (X), said first point (H) lying on the axis of abscissa (X) at a distance from an origin (0) of the Cartesian reference frame (X, Y) equal to an addendum (hi) of the male rotor (2).
