Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a vacuum pump in which material fatigue phenomenon generated by assembly tolerance may not be produced.SOLUTION: This invention relates to a rotary pump in particular that includes a pump system driven by an electric motor, the electric motor has a shaft to be driven (18) and this driven shaft is connected to a driving shaft (16) of the pump system through a connecting device (20). The connecting device has a first connecting hub (22) connected to the driven shaft of the electric motor in such a way that the first connecting hub (22) is fixed in rotation to the driven shaft of the electric motor, has a second connecting hub (24) that is fixed in rotation to the driving shaft of the pump system and has a connecting disc (26) in a force binding hub between the driven shaft and the driving shaft, the connecting disc is connected to the first connecting hub in a rotatable fixed manner by a first linear guiding part and further connected to the second connecting hub (24) by the second linear guiding part in a rotatable fixed manner and in this case, a problem is resolved by an arrangement in which the second linear guiding part is oriented in perpendicular to the first linear guiding part.SELECTED DRAWING: Figure 2
