Abstract
The utility model is a salient pole main and auxiliary synchronous generator, which is composed of a stator assembly, a rotor assembly, a slip ring assembly and a brush yoke assembly. The stator assembly consists of a stator of the main generator and a stator of the auxiliary generator, while a stator frame of the main generator is fixedly connected with that of the auxiliary generator by bolt; the rotor assembly consists of a rotor of the main generator and a stator of the auxiliary generator and is in a segmental structure; the two ends of the rotor field yoke of the main generator are fixed respectively with a shaft head and a support assembly that is provided with a shaft hole, while one end of the rotor shaft of the auxiliary generator is hot jacketed into the shaft hole of the support assembly and the slip ring assembly is fixed o the rotor shaft of the auxiliary generator; the brush yoke assembly is fixed on the right end cover of the main and auxiliary generators. The structural design of the main and auxiliary generators not only takes account the feasibility of manufacturing technique for the motor but also is convenient for using and maintaining the motor. The motor rotor assembly applies the segmental axial structure so as to not only reduce material consumption of the rotating shaft and simplify the processing technique, but also lighten the weight of motor rotor and increase the running reliability of the motor.
Description
Technical field
The utility model relates to generator, is specially the synchronous major-minor generator of a kind of salient pole.
Background technology
Traditional diesel locomotive air-conditioned train power supply is to be provided by the generator car of carrying additionally specially, is powered to train air-conditioning by generator car, not only purchases and safeguards generator car expense height, and take the locomotive traction tonnage.Therefore, need a kind of new type electric generator group, it is used for locomotive, both can be used for traction power supply, can power to air-conditioned train again.
Summary of the invention
The utility model solves the problem that existing diesel locomotive train power supply mode exists, and a kind of traction power supply but also can be to the integrated power generation machine of train power supply not only can realized---the synchronous major-minor generator of salient pole is provided.
The utility model is to adopt following technical scheme to realize: the synchronous major-minor generator of salient pole, comprise the stator assembling, the rotor assembling, the slip ring assembling, the brush holder assembling, the stator assembling is made of the stator of main generator and the stator of subsidiary generator, the out frame of main generator and the out frame of subsidiary generator are fixed with Bolt Connection, the rotor assembling is made of main generator rotor and subsidiary generator rotor and is segmental structure, main generator rotor yoke two ends are fixed with spindle nose respectively and the support assembling of axis hole are arranged on it, one end hot jacket of subsidiary generator armature spindle is in the axis hole of support assembling, the slip ring mount is on the subsidiary generator armature spindle, and the brush holder assembling is fixed on the major-minor generator right end cap with brush holder support.The slip ring assembling is divided into two groups, is connected with major and minor generator amature excitation wire respectively.The main generator of this major-minor generator can be used as the locomotive traction power supply, and subsidiary generator is powered to train air-conditioning.
The utility model is by the improvement to existing diesel locomotive pulling electric generator, formed the synchronous major-minor generator of a kind of salient pole type, make the diesel locomotive pulling electric generator that the power supply of train power supply power supply, particularly train air-conditioning can be provided simultaneously, changed the existing train power supply mode of carrying additionally generator car, not only improve the capacity of locomotive, and saved purchasing and maintenance cost of generator car.
The technological feasibility that motor is made has promptly been considered in this major-minor generator Structure design, is convenient to the operation and maintenance of motor again.The rotor assembling adopts segmentation axle construction promptly to reduce the material usage of rotating shaft, has simplified processing technology again, simultaneously, has alleviated rotor weight, has improved the motor reliability of operation; Slip ring holder structure form is adopted in slip ring assembling, and concentrates vertically and distribute, promptly improved electric machine structure reliability, reduced the manufacturing cost of motor, improved the ventilation condition of motor internal simultaneously.
