现有罗茨风机技术中,电机转子和风机转子分别通过各自的轴承进行定位和支撑,再通过联轴器或三角皮带进行传动,这样的风机结构产品重量和体积大。
发明内容
本发明的目的是将电机部分和风机部分轴承合并,用一套轴承同时完成风机转子和电机转子的轴向和径向定位,简化了罗茨风机的结构,减少了产品重量和体积。
考虑到现有技术的上述问题,根据本发明公开的一个方面,本发明采用以下技术方案:
一种罗茨风机,包括电机转子1、紧固螺钉2、键3、轴承4、从动转子5、主动转子6;
其中,罗茨风机的从动转子5和主动转子6平行排列,每个转子的上下两端分别由一个轴承4进行轴向和径向定位,电机转子1直接安装到主动转子6的上端,主动转子6与电机转子1的径向连接处设有键3,将电机转子1的扭矩传递给主动转子6,主动转子6顶部与电机转子1之间通过紧固螺钉2拧紧,紧固螺钉2旋向与主动转子6的旋向相反,有防松作用。
有益效果:
本发明实现了电机转子与罗茨风机主动转子轴一体化结构,减少了电机转子的定位轴承,简化了产品结构,降低了产品重量。
