Abstract
A cooling device for a rotating machine has a fan assembly coupled with a backing plate. A hub, on the backing plate, secures the cooling device with a shaft. The backing plate includes one or more vents to enable air to exit the cooling device. The fan includes an opening to enable air to enter the cooling device. A chamber is formed between the fan assembly and the backing plate. During rotation, air is drawn into the opening. The air is passed into the chamber and exits through the vents to cool a work surface or working pad attached to the backing plate.

A cooling device for a rotating machine comprising:
- a fan assembly coupled with a backing plate;
- the backing plate including one or more vents to enable air to exit the cooling device;
- the fan assembly including an opening to enable air to enter the cooling device;
- a chamber formed between the fan assembly and the backing plate;
- and
- the fan assembly including a shroud with the opening to enable air to enter the cooling device;
- a separating plate positioned between the shroud and the backing plate;
- a plurality of vanes positioned between the shroud and the separating plate,
- the chamber is formed between the separating plate and the backing plate;
- and
- during rotation of the cooling device, the plurality of vanes are configured to draw air into the cooling device through the fan opening into the chamber and out of the one or more vents in the backing plate to cool a work surface or working pad attached to the backing plate.
