Detachable shaft-hub connection for air blower rotors, especially used in washer-dryers, includes sections locking against rotation and providing resilient detachability

摘要

The rotor hub includes a bush (10) accepting an inserted length (30) of the drive shaft (11) in its central axial opening (12). Interlocked connection prevents relative rotation. Transmission- (30) and fixing- (14) regions are included. The bush is connected to an outwardly- and resiliently expansible wall with U-shaped cross section formed by a connecting- or resilient- component (20). The open end of the bush and the shaft have interlocking sections which snap together; once in this state, the expansible region is relaxed.
