EXCLUDE APPARATUS FOR PREVENTION INFLOW TRACTION ELECTROMOTOR FOR RAILWAY CAR FROM DUST

摘要

The present invention relates to a dust removal device of a traction motor for a railway vehicle that can minimize the dust flowing into the inside when the traction motor is operated, thereby preventing the cooling capacity from dropping and lowering the failure rate. It is formed on the inner lower side in the air inlet 23 of the), the dust removal portion 26 is formed so that the dust in the air introduced by the cooling fan 34 is separated from the lower side by the weight perpendicular to the ground by its own weight is formed The discharge hole 36 is positioned inside the main body 20 so that the suction force is generated so that the dust dropped on the dust removing unit 26 is sucked by the discharge pressure generated at the discharge port 36 of the main body 20 and discharged. The flow passage 25 is formed to be located at the side of the discharge port 36, and the air from which the dust introduced along the air inlet 23 is removed is bent by the divider 24 to be introduced into the main body 20. Ground to flow into It has a feature configured to purge air inlet 28 formed at a position which is horizontal.
