A kind of high-power locomotive traction blower fan drive motors

Technical field

The utility model relates to a kind of high-power locomotive traction blower fan drive motors, and as a kind of driving arrangement of Harmony high-power locomotive traction blower fan, motor provides actuating force for Harmony high-power locomotive traction blower fan.

Background technology

The cooling blower of locomotive traction motor mostly is totally enclosed both at home and abroad at present, and complete machine degree of protection IP55 is terminal box degree of protection IP56 wherein.This drive motor is the horizontal outside that is installed in blower fan, and the motor driven blower fan provides cooling air for locomotive traction motor, and the heat that traction electric machine produces is taken away.Motor adopts inverter supply, class of insulation H level, insulating material to have low cigarette, halogen and characteristic such as fire-retardant.Different because of the particularity of factors such as the mounting condition of this motor and environment for use and common motor, there is poor radiation in existing motor, and safety and reliability are low.The dynamic balancing grade of rotor is lower, and electric moter noise and vibration are big.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned defective, provides that a kind of compact appearance is attractive in appearance, thermal diffusivity good, vibrates for a short time, and noise is low, the high-power locomotive traction blower fan drive motors that property safe and reliable to operation is high.

The technical solution of the utility model is: a kind of high-power locomotive traction blower fan drive motors, comprise the total piece installing of terminal box, water joint, front end housing, bearing, stator and rotor, rotating shaft, support, rear bearing inner cap, rear end cap, fan blade and fan housing, it is characterized in that:

In the described support stator is housed, stator is fixed on the support by holding screw, and front end housing and rear end cap are fixed on the support two ends, and the total piece installing of rotor is arranged in the motor stator;

There is bearing at described rotating shaft two ends, bearing is contained in front end housing and the bearing room of back top cover, this rear end cap is equipped with the rear bearing inner cap, fix bearing by the bearing cap set bolt, the rotating shaft front end extends outside the front end housing by bearing, fan blade is equipped with in the rotating shaft rear end, and fan housing is fixed on the support, and power line is drawn and power connection from terminal box by water joint;

Described front end housing is provided with the loosening butterfly spring in anti-upper bearing (metal) outer ring, and rear end cap is provided with the air vent hole rubber stopper, condenses in motor to prevent water gas;

The bearing that the utility model uses is non-maintaining deep groove ball bearing, and rear end bearing is fixed, and preceding end bearing is equipped with butterfly spring outward, in case bearing outer ring is loosening and play damping effect simultaneously to the rotor thermal expansion spacing; Motor adopts anticorona H class F insulating material F and has low cigarette, nontoxic, fire resistance, to adapt to the locomotive safety requirements; Motor is installed on the interior mounting bracket of locomotive by the installation screw on the support, and fin is arranged on the motor bed-plate, and the motor heat exhales from fin; The degree of protection of terminal box and power line water joint all is IP68.Band air vent hole rubber stopper is housed on the rear end cap, condenses in motor to prevent water gas; This structure can effectively be fit to this kind locomotive operation external environment condition.

The utility model is as Harmony high-power locomotive traction motor cooling blower drive motor, its operating state is that motor mounting is on traction electric machine top, the stable performance of blower fan and motor, motor have that compact appearance is attractive in appearance, thermal diffusivity good, vibrate little, safe and reliable to operation.
