Abstract

本实用新型公开了一种螺杆压缩机转子，它包括阴转子1和阳转子2，其特征在于阴转子1和阳转子2的双边非对称，其组成曲线均为圆弧或圆弧包络线，阴阳转子的齿数比为6∶5，阴转子1和阳转子2之间的间隙为0.04～0.1mm，阴阳转子间完全实现“曲面对曲面”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，且在同等功率档次的产品中，其直径和中心距最大。本实用新型密封性好、效率高、转速低、噪声低、振动小，寿命长，还便于加工和检测。

Description

一种螺杆压缩机转子
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GHH公司的型线，瑞典ATLAS公司的SRM型线，台湾复盛公司的型线，日本日立公司的型线等等，这些型线选取不同的曲线及其组合，主要由椭圆、圆弧、圆弧包络线、点、直线、摆线等组成，由于设计取向不同，具有各自的优缺点。由于上述螺杆压缩机转子由不同的型线组成，容易在接触带产生横向泄漏，降低压缩机的效率，且这些螺杆压缩机中转子的直径都较小，因而转速较高，在实际使用中噪声、振动较大，且刚性不足，影响其使用寿命，而螺杆压缩机转子型线设计的复杂性，还造成其加工方法比较复杂，对加工精度、杂质、和油碳化物的敏感性较大。
发明内容
本实用新型要解决的技术问题是提供一种新型的螺杆压缩机转子，它与现有技术相比，是在转子间完全实现“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；与其他类型同功率范围的转子相比，增加其直径和中心距，降低其转速，从而降低噪声和振动，并使其刚性得以提高，从而延长其使用寿命；由于完全是曲面对曲面，便于采用磨削加工，也更容易检验，对加工精度、杂质和油碳化物的敏感性较小。
本实用新型的目的可以通过以下措施来达到：一种螺杆压缩机转子， 包括阴转子1和阳转子2，阴转子1和阳转子2的双边非对称，组成曲线为圆弧或圆弧包络线，转子间完全实现“曲面对曲面”的密封，阴阳转子的齿数比为6∶5，阴阳转子之间的间隙为0.04～0.1mm，以阴转子1的中心点为坐标原点，阴转子1、阳转子2的有间隙的实际型线坐标如下：
