<p>In a device for assembling an impeller (1) on a driving shaft (36) the impeller is supported on the driving shaft by a radial bearing (3) having a small radial clearance. This bearing admits a relative rotary motion between impeller and shaft. An elastic or resilient element (9) is mounted between the shaft and the impeller to transmit the torque from the shaft to the impeller.</p> |
