Abstract
A hub assembly for a fan reduces transmission of vibrations between the fan motor and the fan blades. The hub assembly comprises a motor assembly, a hub, and a plurality of resilient members. The motor assembly includes a motor and a motor housing surrounding the motor, and the motor is configured to rotate the motor housing during operation. The hub is supported on the motor housing by a plurality of fasteners. The resilient members are at least partially interposed between the hub and the motor housing, and each resilient member of the plurality of resilient members surrounds a portion of a corresponding fastener of the plurality of fasteners.
