Abstract
The utility model relates to a drive motor of a blower fan of a locomotive cooling tower, serving as a driving device for an exported locomotive cooling tower. The drive motor comprises bearing outer covers, bearings, end covers, bearing inner covers, a rotary shaft, a rotor general assembly, a stator, a base, a waterproof joint and the like. An outer ring of a rear end bearing of the motor is tightly attached on and is clamped and fixed by a bearing cover. A gap is arranged in an outer ring of a front end bearing, leaving space for thermal expansion to prevent the bearings from being jammed. The motor is arranged at an inner side of the blower fane, the base is provided with cooling fins, and heat generated by the motor is radiated by wind flowing in the blower fan. To reduce motor vibration, an extremely high requirement for the dynamic balance level of the rotor is required, and the full-sealed structure of the motor enhances the waterproof and dustproof capability of the motor. The motor has low-smoke, nontoxic and flame-resistant performances. The protection grade of the waterproof joint made of exotic materials is IP68.

Summary of the invention
Deficiency and the defect that is to overcome prior art of the present utility model, provide a kind of heat-resisting ability strong, the locomotive cooling tower blower fan drive motor of the characteristics such as vibration and noise is low, nonmetallic materials have low cigarette, nontoxic and water proof and dust proof.
the technical solution of the utility model is: a kind of locomotive cooling tower blower fan drive motor, comprise the fore bearing enclosing cover, bearing, front end housing, the fore bearing inner cap, rotating shaft, the total piece installing of rotor, tight ingot screw, stator, support, earth stud, water joint, the rear bearing inner cap, rear end cap and rear bearing enclosing cover, it is characterized in that described front end housing and rear end cap are fixed on the support two ends by bolt of cover, in this support, stator is housed, stator is fixed in support by tight ingot screw, the total piece installing of rotor is arranged in stator, the total piece installing of rotor is rotated in stator by magnetic fields,
There is bearing at described rotating shaft two ends, and this bearing is contained in the bearing chamber of front end housing and rear end cap and by bolt of bearing cap, fixes; Bearing is the high temperature resistant self-lubricating seal deep groove ball bearing;
Described earth stud and water joint are contained on the wire hole of support, and the water joint on the power line wire hole is drawn from stator.Switch on power, to motor, provide power.
The bearing that this motor uses is the high temperature resistant self-lubricating seal deep groove ball bearing, and the rear end bearing outer ring is close to and is clamped fixingly with bearing cap, and the front end bearing outer ring is gapped, gives the thermal expansion spacing, prevents that bearing is stuck; Motor adopts anticorona H class F insulating material F and has low cigarette, nontoxic, fire resistance, to adapt to the locomotive safety requirements; This motor is arranged on the blower fan inboard by the installation screw on support, and fin is arranged on motor bed-plate, and the heat that motor relies on wind mobile in blower fan to produce exhales from fin; The degree of protection of the power line water joint that exotic material is made reaches IP68.This structure can effectively be protected the normal operation of motor and suitable vent external environment.The nonmetallic materials such as H class F insulating material F in motor have low cigarette, nontoxic and high-temperature stability.
The utility model isThe characteristics such as the locomotive cooling tower blower fan provides actuating force, and its operating state is the inboard that motor is arranged on cooling blower, and it is strong that motor has the water proof and dust proof ability, and the class of insulation is high, high temperature resistant;
ThisThe stable performance of blower fan of cooling tower drive motor, safe and reliable to operation.
