ABSTRACT:
In a rotary fan (10) having a tubular drive shaft (14) and a lower cylindrical hub (16), an isolator bushing (20) interconnects the drive shaft (14) and hub (16) so as to substantially reduce vibrations. The bushing (20) is elastomeric, tapered and mounted within the hub (16) in an uncompressed state to maintain vibration-reducing properties. The drive shaft (14) extends into and terminates within a central bore (42) of the bushing (20), and the end portion of the shaft (14) is secured at a lower portion of the bushing (20). The hub (16) is secured to an upper end surface of the bushing (20) and the length of the bushing (20) provides dampening of vibrations caused by rotary motion. The tapering of the bushing (20), while maintained in an uncompressed state, provides dampening of vibrations caused by resonant frequency characteristics.
