[实用新型]一种螺杆压缩机转子

摘要

一种螺杆压缩机转子，其结构包括双边为非对称的阴转子、阳转子，它们的组成曲线为圆弧及其包络线，齿数比为5∶4，且阴阳转子之间具有间隙，其特征在于：以阴转子的中心点为坐标原点，阴阳转子之间的间隙为0.02－0.06mm，按其实际型线坐标制造的转子具有“曲面对曲面”、“大转子、低转速”的特点。本实用新型与已有技术相比，具有完全实现“曲面对曲面”密封，从而有助于形成流体动力润滑膜，降低通过接触带的横向泄漏，提高压缩机效率；以及改善转子的加工、检验性能，采用大转子、低转速设计思路后，可以降低噪声和振动，提高转子刚性，延长使用寿命，相对减小对加工精度、杂质和油碳化物敏感性的优点。
