Abstract
A shaft generator with a rotor cooling system comprises a stator, a rotor, a rotor shaft, an enclosure, a fan, an air shield, a front end cover, a rear end cover and a belt wheel. The stator is fixed in the front end cover. The rotor shaft penetrates through the belt wheel, the front end cover, the rotor, the rear end cover and the fan successively. The rotor is located in the stator. The front end cover and the rear end cover form a sealed cavity in which the stator and the rotor are enclosed. The fan and the belt wheel are arranged at the two ends of the rotor shaft. The front end cover and the rear end cover are installed in the enclosure. The air shield is arranged at one end of the enclosure in a covering manner. The fan is located in the air shield. The rotor shaft is hollow and tubular in structure. The shaft generator has the beneficial effects that the self-weight of the rotor is reduced, the rotational inertia is reduced, and rolled steel is saved. The ventilation and heat dissipation of the generator rotor is guaranteed so that the requirement for normal work in high-temperature environment can be satisfied, and the shaft generator has better waterproof sealing property.
Description
Technical field
This utility model relates to a kind of shaft belt type generator, and particularly a kind of shaft belt type generator with rotor cooling system, belongs to machine field.
Background technology
Permanent magnetism axle generator is because inside is full closeding state, inside can not ventilate, heat relies on stator casing heat radiation entirely, therefore internal rotor temperature can raise, and the excess Temperature of magnet steel, can make field weakening, thereby generator output voltage is reduced, caused cold and hot voltage difference excessive, in order to guarantee that rotor can well dispel the heat, just internal heat need to be dispersed into the external world by a kind of mode.
Common generator is cooling comprises two kinds of air-cooled and water-cooleds, air-cooled is by the fan with in motor, to brush heat generating components to lower the temperature, but because permanent magnetism axle generator inside is full-closed structure, inner obstructed ventilation, heat relies on stator casing heat radiation entirely, air-cooled is by fan, the heat of stator casing to be blown away, and this cooling effect is poor; Water-cooled is to adopt liquid medium cooling, for example the relative cooling capacity of water is air 50 times, takes away same heat, and the flow-rate ratio air of required water is much smaller, therefore, in coil, adopt a part of hollow conductor, in wire water flowing cooling, just can greatly reduce electric machine temperature rise, delay ageing of insulation, increase electrical machinery life, but this complex structure, for the small generator of compact conformation, cannot use this kind of cooling means.
Summary of the invention
Goal of the invention: the purpose of this utility model is to provide a kind of by ventilating in the middle of armature spindle, rotor temperature is remained on to the shaft belt type generator with rotor cooling system of a best state.
Technical scheme: a kind of shaft belt type generator with rotor cooling system, comprise stator, rotor, armature spindle, casing, fan, fan housing, front end housing, rear end cap and belt wheel, described stator is fixed on front end housing inside, described armature spindle is successively through belt wheel, front end housing, rotor, rear end cap and fan, described rotor is positioned at stator interior, described front end housing and rear end cap form an airtight cavity stator and rotor are enclosed in wherein, fan and belt wheel are positioned at armature spindle two ends, described front end housing is arranged in casing together with rear end cap, fan housing is sleeved on casing end, described fan is positioned at fan housing inside, described armature spindle is the tubular structure of hollow.Generator rotor shaft adopts hollow tubular structure, during generator rotation, cooling air enters armature spindle inside from the spindle nose of belt wheel one end, the heat that armature spindle and magnet steel are produced by hollow rotor shaft by fan sucking-off, then by fan sucking-off and blow to generator outside and dispel the heat, greatly improved the heat dispersion of generator amature.
Preference, in order to improve the air draught ability of fan, described fan housing is provided with fan housing ventilation hole, and described fan housing central diameter is less than or equal to the region of armature spindle diameter and does not offer fan housing ventilation hole.
Preference, for the air draught ability of further fan, thus the heat dispersion of raising rotor, the circumference of described casing external diameter is provided with ventilation slot, and fan housing inside is communicated with outside by ventilation slot, with the hot-air of heat, by ventilation slot, discharges.
Beneficial effect: the utility model has alleviated the own wt of rotor, has reduced moment of inertia, has saved steel; Guarantee the ventilation and heat of generator amature, met the normal work under hot environment; Also has good waterproof sealing simultaneously.
