Servo motor main shaft heat abstractor

The utility model discloses a servo motor main shaft heat abstractor, including cup jointing at main epaxial heat conducting ring, the heat conducting ring surface outwards extends has the combinationof multiunit heat dissipation flabellum, and the heat dissipation flabellum combination of every group is including two parallel arrangement's fin, also including discoid scattered heat exchanger, beequipped with the shaft hole on the heat exchanger that looses, the main shaft passes the heat exchanger's that looses shaft hole, and the heat exchanger verso that looses is equipped with a plurality of air inlets, installs the intake pipe on the air inlet, the top surface of the scattered heat exchanger back and motor passes through the connecting rod to be fixed, through the forced -air cooling heat dissipation mode, can effectively realize the heat dissipation of main shaft, reduce the main shaft temperature, unique design's double leaf structure when can take away the heat fast, reducesthe wind resistance factor
