专利名称：一种螺杆压缩机转子的制作方法
技术领域：
本实用新型涉及一种转子，尤其涉及一种螺杆压缩机转子。
背景技术：
螺杆压缩机中，转子的形状基本决定了螺杆压缩机的性能，目前世界上已有的有代表性的转子型线主要有德国某公司的型线，瑞典某公司的型线，以及台湾、日本等公司的型线，这些型线选取不同的曲线及其组合，由于设计取向不同，应该说各有各的优缺点。但是，现有技术存在的共同缺点是转子直径较小导致转速高，在实际应用中会出现噪声、振动大、刚性不足，从而影响使用寿命。
发明内容
本实用新型的目的在于提供一种新型的螺杆压缩机转子，其设计取向是转子间完全实现“曲面对曲面”的密封，而不包含任何“曲线对曲线”的密封，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；改善转子的加工性能，便于采用磨削法加工，也更容易检验；大转子、低转速，以降低噪声和振动，提高转子刚性，延长使用寿命。对加工精度、杂质和油碳化物的敏感性小。
为克服现有技术的上述不足，本实用新型采用了如下技术方案，这种螺杆压缩机转子，包括阴转子、阳转子，阴转子和阳转子的双边非对称，组成曲线为圆弧及其包络线，阴阳转子的齿数比为6∶5，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，其实际型线坐标如下
具体实施时，阴阳转子之间的间隙为0.05mm。
本实用新型与已有技术相比，由于采用了本型线使转子间完全实现了“曲面对曲面”的密封，而不包含任何“曲线对曲线”的密封，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。由于完全采用了圆弧或圆弧包络线，从而改善转子的加工性能，便于采用磨削法加工，也更容易检验。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，也对加工精度、杂质和油碳化物的敏感性相对减小。

2.如权利要求1所述的一种螺杆压缩机转子，其特征是阴阳转子之间的间隙为0.05mm。
专利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6∶5，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。
