| 摘要 |
<p>The invention relates to a magnetically driven pump so designed that a drive power of an electric motor (15) is transmitted from a magnets-embedded drive rotor (16) to a magnets-embedded follower rotor (14) opposed to one another by way of a magnetic coupling, the follower rotor (14) and an impeller (5) being secured respectively to the opposite ends of a rotating shaft (4) to which a thrust bearing (3b) of ceramic material is fastened for receiving an axial load. A cushioning member (7), for example, a dish-shaped plate spring, is mounted on the rotating shaft (4), so as to push the thrust bearing (3b) from the rear, in the position between the thrust bearing (3b) and a flange (6) provided on the rotating shaft (4) for determining the position of the follower rotor (14).</p> |
