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，尤其涉及一种空气螺杆压缩机转子。
背景技术：
螺杆压縮机中，转子的形状基本上决定了螺杆压縮机的性能，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、闩本等公司的型 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空气螺杆压縮机转子，其设计取向是转子间完 全实现"曲面对曲面"的密封，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，提高压縮机效率；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 用了如下技术方案该螺杆压縮机转子，包括阴转子、阳转子，阴、阳转子为双边非对称型 线，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0.02-0.06,，其实际 型线坐标如下
阳转子

具体实施时，阴、阳转子之间的间隙为0.05mm。
本实用新型与己有技术相比，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，提高压縮机效率；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，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。
附图为本实用新型阴阳转子在直角坐标系中端面形状示意图。
具体实施方式
以下结合附图对本实用新型的具体实施方案作详细说明
实施例 一种空气螺杆压縮机转子(参见图)，它包括阴转子l、阳转子2，阴转子l和 阳转子2为双边非对称型线，组成曲线均为圆弧或圆弧包络线，阴转子的齿数为6，阳转子
的齿数为7，阴阳转子之间的间隙为0.05mm，考虑到加工误差问题，间隙可放宽至0. 02-0. 06

2、如权利要求l所述的一种螺杆压縮机转子，其特征是阴阳转子之间的间隙为O. 05rmi。
专利摘要一种空气螺杆压缩机转子，其结构包括双边为非对称的阴、阳转子，它们的组成曲线为圆弧及其包络线，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，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，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。
