具有偏心驱动叶片的真空泵
Abstract:
本申请涉及具有偏心驱动叶片的真空泵。具体地，本发明涉及一种真空泵(1)，特别地涉及一种旋转叶片泵，其包括：壳体(50)，其限定具有入口和出口的腔(52)；叶片构件(14)，其用于腔(52)内侧的旋转驱动移动；能够驱动的转子(8)，其在腔(52)内侧；能够旋转的中心轴(6)，其延伸到腔(52)，其中叶片构件(14)被能够滑动地布置在转子(8)中，转子(8)能够与所述叶片构件(14)一起旋转。根据本发明，中心轴(6)包括曲柄销(16)，曲柄销(16)接合转子(8)的相应的引导凹部(18)，用于至少沿着第一预定旋转角度(α)驱动转子(8)。本发明还涉及一种方法。
Abstract(English):

A vacuum pump includes a housing defining a cavity having an inlet and an outlet; a vane member for a rotary driven movement inside the cavity; a drivable rotor inside the cavity; and a rotatable central shaft extending to the cavity. The vane member is slidably arranged in the rotor. The rotor is rotatable together with the vane member. The central shaft comprises a crank pin configured to engage a respective guiding recess of the rotor for driving the rotor at least along a first predetermined rotational angle.
