Description
技术领域
本实用新型涉及一种转子，尤其涉及一种大型螺杆式压缩机转子。
背景技术
螺杆式压缩机有一对相互啮合的按一定传动比反向旋转的螺旋形转子，水平且平行配置于机体内部，具有凸齿的转子为阳转子，通常为驱动转子，具有凹齿的转子称为阴转子，通常为从动转子。螺杆式压缩机属于容积式压缩机，它利用一对相互啮合的阴阳转子在机体内作回转运动，周期性地改变转子每对齿槽间的容积完成吸气、压缩、排气过程。
螺杆式压缩机转子的齿形决定螺杆式压缩机的性能。目前螺杆式压缩机转子的齿形组成曲线有圆弧、摆线和椭圆及其包络线等，但阴阳转子的齿数比一般为6∶5，阴阳转子的直径差较大，阴转子直径较小，不适合阴转子驱动阳转子，且因转速比为1.2倍，对螺杆式压缩机排气量的提高有限；由圆弧、摆线及其包络线组成的螺杆式压缩机转子的齿形存在尖点棱角，不利于加工和检测，噪声较大。
发明内容
本实用新型的目的在于克服上述现有技术的不足而提出一种易于加工，啮合面光滑，密封性好，阴阳转子的直径差小，可互换驱动转子，振动小，噪声低，提高螺杆式压缩机的排气量和效率的螺杆式压缩机转子。
本实用新型的目的可以通过如下措施来达到：参见附图，一种大型螺杆式压缩机转子，它包含阴转子1和阳转子2，其特征在于阴转子1和阳转子2的齿形为双边非对称，齿形的组成曲线为圆弧和椭圆及其包络线，阴阳转子的齿数比为7∶5，阴阳转子的直径分别为248mm和262mm，阴阳转子的中心距为206mm。
本实用新型同现有技术相比可产生如下积极效果：
1.转子的齿形组成曲线为圆弧和椭圆及其包络线，接触线短，泄漏三角形小，啮合平稳，密封性好，效率高；
2.各组成齿形曲线间光滑连接，型线上无尖点，便于加工和检测，流线性好，噪声低；
3.节圆处成点啮合，使整个啮合线均可形成油膜；
4.齿形为双边非对称，阴阳转子直径调整方便，转子间力矩分配合理，振动小；
5.阴阳转子的齿数比为7∶5，转速比为1.4倍，阴阳转子直径相差不大，转子刚度接近，承载能力高，可用于压差和压比较大的工况，可实现阴转子1驱动阳转子2，减少压缩机的开发系列。
我们知道，一种规格转子的螺杆式压缩机当R22制冷剂更换成R134a制冷剂时，其制冷量和功率降低至0.7左右，也就是说，要制冷量不变，通常的技术是用大一个规格转子的螺杆式压缩机。而采用本实用新型的技术，阴阳转子的齿数比为7∶5，转速比为1.4倍，不用增大一个规格转子，就用原规格转子实现了制冷量不变，且因排气量的提高，容积效率将提高，压缩机性能也就提高；对该规格转子螺杆式压缩机而言，因转子规格相同就可压缩机的铸件通用，因转子齿形通用则加工齿形的刀具通用，从而可以减少机型的开发和刀具的投入，可以大大节省开发成本，加快开发进度，使螺杆式压缩 机有更广的应用领域。
