20130082578 | DYNAMOELECTRIC MACHINE HAVING AN INTEGRATED FAN - A dynamo-electric machine, in particular a multi-pole dynamo-electric machine includes a shaft and an integrated fan which is connected to the shaft by a friction-wheel planetary gear. The friction-wheel planetary gear has first and second rolling bearings, with the first rolling bearing having an outer ring mounted in the hub of the fan, and the second rolling bearing having an outer ring which is press-fitted in the hub of the fan. Arranged between the first and second rolling bearings is a driving bush for transmitting a rotational speed of the shaft onto balls of the second bearing to thereby increase a rotational speed of the fan by a predefined factor compared to the rotational speed of the shaft. | 04-04-2013 |
