ABSTRACT:
A vibration damper for a suspended ceiling fan comprising a motor mounting and a frame support plate, totally enclosed in a vibration absorbing rubber compound. The motor mounting and frame support plates are separated by an annular space that forms an outward facing annular channel. Trapezoidal shaped reinforcement ribs located in the outward facing annular channel restrict swaying of the fan blades when the motor is energized. The damper may comprise two arcuate shaped members which allows easy installation on existing ceiling fans and easy disassembly when the fan motor needs maintenance or repairs.
