CN106499629A 一种罗茨风机转子组件 无效 - 驳回

一种罗茨风机转子组件
摘要：
本发明涉及一种罗茨风机转子组件，包括转子轴(1)、转子(2)、螺钉(3)、垫片(4)和定位孔子(2)，转子(2)为三叶，转子轴(1)形状与转子(2)形状保持一致，每个叶形一端通过螺钉(3)和垫片(4)将转子(2)轴向固定在转子轴(1)上，每个叶形的另一端设有定位孔(5)。本发明的罗茨风机转子组件，转子沿型面厚度均匀，保证不同温度下最终型线；端面通过螺钉压紧保证轴向固定，降低了产品重量，并大大降低风机卡滞现象。(5)；转子轴(1)外层紧度镶套配合非金属材料转
摘要（英）：

The invention relates to a Roots blower rotor assembly, which comprise a rotor shaft (1), a rotor (2), a screw (3), a pad (4) and a location hole (5). The rotor shaft (1) is externally sleeved with and matches a rotor (2) which is made of a non-metallic material and is shaped as a trefoil. The shape of the rotor shaft (1) is consistent with the shape of the rotor (2). The rotor (2) is axially fixed on the rotor shaft (1) through a bolt (3) and a gasket (4) at one end of each leaf shape, and the other end of each left shape is provided with a location hole (5). According to the Roots blower rotor assembly, thickness of the rotor along the profile is uniform such that the final molded line is guaranteed at different temperatures; and the end face is tightened by the bolts so as to guarantee the axial fixation and reduce weight of the product and greatly decrease clamping stagnation of a fan.
