FAN FOR MOVEMENT OF HOT GASES Russian patent published in 2015 - IPC F04D29/00 

FIELD: machine building.

SUBSTANCE: fan comprises a working chamber which contains an impeller fixed on the driven shaft, a coupling comprising the driving half-coupling combined with the driving shaft, and the driven half-coupling fastened to the driven shaft, and the driving and driven half-couplings are installed with a gap, and the electric motor. The coupling is designed as a flange coupling, hubs of the driving and driven half-couplings are connected to flanges by means of blades installed evenly along a circle, and flanges of the driving and driven half-couplings are fitted with air vents. The driving shaft is connected with the electric motor shaft by means of V-belt transmission.

EFFECT: design reliability improvement at the expense of intensification of fan shaft cooling process at simultaneous simplification of the device design and decrease of energy consumption.
