前述坐标值可以采用任一长度单位(如均为毫米)，因为只要压縮机转子具有都述形状 的型线即可，其具体尺寸可按相同比例放大或縮小。
所述阴转子齿与所述阳转子齿的数量不等，优选的，所述阴转子齿的数量多于所述阳转
于齿的数量，如所述阴转子齿为7个，所述阳转子齿为5个。
本实用新型相对于现有的螺杆式压縮机转子来说，由于转子采用不对称结构，作为主动 转子的阳转子其齿数少，齿相对较厚，刚度好，具有较小的热变形及弯曲变形，强度也较高， 不易损坏；齿的型线无尖点，齿面光顺连接，便于加工与检测，振动小，噪音低，转子齿高 半径和齿顶高合理，面积利用系数大；在工作时输气量大，效率高。

其中，各离散点的坐标原点为阴转子的中心，以上各离散点的值为理论值，在制造加工 时，考虑制造成本及精度要求为其预留一定的公差范围。本实施例相对于现有的螺杆式压縮机转子来说，由于转子采用不对称结构，作为主动转 子的阳转子其齿数少，齿相对较厚，刚度好，具有较小的热变形及弯曲变形，强度也较高， 不易损坏；齿的型线无尖点，齿面光顺连接，便于加工与检测，振动小，噪音低，转子齿高 半径和齿顶高合理，面积利用系数大；在工作时输气量大，效率高。
