Abstract
A shaft bearing device for a pump includes an antifriction bearing, which can be connected to an axially displaceable pump shaft. A spring is arranged at the antifriction bearing in such a way, that a spring force can be transmitted to an outer ring of the antifriction bearing by the spring in a mounting condition of the shaft bearing device. A lifting element attached to the pump shaft and a corresponding counter element are separated from each other by the spring force in a starting state and/or in a shutdown state of the pump.
Claims17
A shaft bearing device for a pump, comprising;
- an antifriction bearing configured to be connected to an axially displaceable pump shaft;
- and
- a spring arranged at the antifriction bearing such that a spring force is capable of being transmitted to the antifriction bearing by the spring in a mounting condition of the shaft bearing device such that a lifting element attached to the pump shaft and a corresponding counter element are separated from each other in at least one of a starting state and a shutdown state of the pump.
