Abstract
The invention relates to a single-bearing generator, which comprises a connecting disc, an engine base, a coupling, a stator, a rotor, an outlet box, an exciter stator, an exciter rotor, a rotary rectifier module, a rear end cover, a bearing cover, a bearing, a protective cover and a rotating shaft. According to the single-bearing generator, air cooling is adopted as a cooling manner, and cold air enters from an air inlet of the rear end cover and is exhausted from an air outlet at the front end of the generator. Because the engine base is directly connected with an oil engine, a ventilation device is arranged at the rear end of the generator, and therefore the axial sizes of the engine base and the rotating shaft are reduced. Meanwhile, cooled air can be distributed through the ventilation device, wherein one path of cooled air enters the generator to cool the motor, and other one or two paths of cooled air enters other equipment to play a cooling role. The single-bearing generator disclosed by the invention is compact in structure, high in reliability and particularly suitable for being used on motor-driven mining machinery.
Description
Technical field
The present invention relates to a kind of generator, relate in particular to a kind of single-bearing generator.
Background technology
Generally the diesel engine generator fan fills the generator front end, and generator is connected by front end of shield with oil machine, the axial dimension of electric machine stand and rotating shaft can be larger like this, its rigidity is relatively poor, generator of the present invention adopts support directly to be connected with oil machine, and ventilation unit has shortened the axial dimension of support and rotating shaft in the generator rear end, electric generator structure is compact, Reliability Enhancement.Simultaneously cooling-air can distribute by ventilation unit, and one the tunnel enters generator cools off motor, the one road or two-way enter other equipment and play cooling effect.
Summary of the invention
The object of the present invention is to provide a kind of single-bearing generator, this electric generator structure is compact, is particularly suitable for using on power-actuated mining machinery.
The present invention realizes like this, it comprises terminal pad, support, shaft coupling, the main frame stator, main rotor, wire box, exciter stator, exciter rotor, the rotary rectifier module, rear end cap, bearing cap, bearing, rotating shaft, it is characterized in that terminal pad, shaft coupling, main rotor, exciter rotor, bearing is contained in and consists of rotor on the alternator shaft, the rotary rectifier module is contained in exciter rotor, the main frame stator is contained in the support, wire box is contained in the support top, exciter stator is contained on the rear end cap, rear end cap is connected with support by bolt, bearing cap is to the bearing axial location, seam is arranged on the commutator end bearing support bracket, there is the taper shaft extension rotating shaft rear end, the support front end has seam to be connected with flywheel shell of diesel engine, there is seam to be connected with diesel engine flywheel on the terminal pad, bearing is rolling bearing, and individual square is arranged on the terminal pad, four bights be used for generator with rotor is played a supportive role before diesel engine is connected.
Technique effect of the present invention is: because generator adopts support directly to be connected with oil machine, ventilation unit has shortened the axial dimension of support and rotating shaft in the generator rear end, and electric generator structure is compact, Reliability Enhancement.Simultaneously cooling-air distributes by ventilation unit, and one the tunnel enters generator cools off motor, the one road or two-way enter other equipment and play cooling effect.
