Abstract (en)
[origin: WO2020007665A1] The invention relates to a dual or multi-shaft vacuum pump comprising a motor, a first shaft and at least a second shaft, wherein the first shaft and the second shaft are driven synchronously by the motor via a common drive belt. The first shaft has a pumping element, and the second shaft likewise has a pumping element, which cooperates with the pumping element of the first shaft in order to convey a gaseous medium from an inlet to an outlet. The first shaft has a first emergency running gear, and the second shaft likewise has a second emergency running gear, which meshes with the first emergency running gear.
