The utility model is the deficiency solved the problems of the technologies described above, and the technological scheme adopted is:
A kind of front step bearing radiation system of motor of kiln Heating Cyclic blower fan, this radiation system is arranged in fan body, described fan body be one by slip ring, spiral case, impeller, the straight connection type blower fan that insulation block and motor are formed, described radiation system comprises heat-dissipating impeller, wind deflector and air channel, heat-dissipating impeller is arranged on the transmission shaft of motor, wind deflector is arranged on the front cover of motor after coordinating by gap running-on with heat-dissipating impeller, the front cover of motor offers inlet hole, described air channel be one by inlet hole, the air passageways that the inner chamber of wind deflector and the exhaust port of heat-dissipating impeller are formed, by the cool air flowed in air channel, the bearing in motor front end cover is dispelled the heat.
Wind deflector stretches in heat-dissipating impeller, is namely inserted in, and this makes running-on coordinate.Gap refers to that wind deflector is inserted in afterwards and heat-dissipating impeller keeps certain radial clearance, and this matching relationship is exactly that gap running-on coordinates.
The through hole of described inlet hole to be one along the front cover circle distribution of motor and with the front cover center line of motor be 40-50 ° of angle.
The through hole of described inlet hole to be one along the front cover circle distribution of motor and with the front cover center line of motor be 45 ° of angles, motor is the special B5 motor of extension shaft, and the front cover of motor is special design structure, and circumference is drilled with oblique 45 ° of inlet holes.
What described heat-dissipating impeller adopted is straight shroud, can compress axial dimension like this, saves space, can shorten motor size cantilever further.Heat-dissipating impeller also can do tapered or circular arc.
The beneficial effects of the utility model are: 1, the utility model adopts the mode of air cooling to dispel the heat to bearing, effectively can overcome the defect of conventional fan bearing heat radiation, and this mode also more easily realizes, and can not cause bearing locking because of local temperature difference.This new structure realizes the heat radiation to bearing by the rapid air movement at inclined hole place on the bearing (ball) cover of motor front end.
2, the independently radiation system shown in the utility model.What heat-dissipating impeller and wind deflector formed is leading portion bearing independence radiation system, and the inclined hole of air-flow on the front cover of motor enters heat-dissipating impeller by wind deflector, is realized the heat radiation of bearing by the air flowing at wind deflector suction port place.
