Abstract
The utility model discloses an assembly guiding plate for a medium-sized generator, relating to assembling devices for generators. The guide plate is made of an insulating material, and a circular hole is arranged in the center of the guide plate, wherein the diameter of the circular hole matches with that of a motor rotor shaft, and the external diameter of the guide plate is between the maximal external diameter of a rotor and the internal diameter of a stator; so that in the assembling process the distance from the rotor to the stator is always maintained in 1-2mm, thereby effectively avoiding collision between the rotor and the stator. According to the utility model, a motor is assembled in a vertical manner, the guiding plate is utilized, and the generator rotor directly enters into the generator stator relying on the deadweight of the rotor of the medium-sized permanent-magnetic generator, wherein press mounting is not required. The assembly guiding plate for the medium-sized generator has the advantages that structure is simple, operation is convenient, collision between the motor stator and the motor rotor can be avoided in the assembling process, and the production cost of the generator is reduced.
Description
Technical field
The utility model relates to a kind of generator assembling device, particularly a kind of middle generator assembling guided plate.
Background technology
Because the space between permanent magnet generator stator and the rotor is smaller, only have several millimeters, and the permanent magnetic material in the permanent magnet machine rotor is a kind of ferromagnetic material that very big magnetic is arranged, medium-sized generator amature is heavier in addition, when adopting traditional horizontal assembling mode to assemble motor, rotor is easy to scratch with stator core in assembling process, thereby cause the permanent magnetic material surface coating destroyed easily, even make permanent magnetic material chipping, be conventional tool and the hydraulic system structure complexity of avoiding this problem to make, operation inconvenience, most importantly cost is higher, has increased the production cost of generator.
The utility model content
The purpose of this utility model is the defective that has overcome conventional tool and hydraulic system, has made a kind of middle size motor assembling guiding device.
Guiding device is a guided plate of being made by insulating material, at the guided plate center circular hole is set, the diameter of circular hole and rotor shaft diameter are complementary, the external diameter of guided plate is between rotor maximum outside diameter and diameter of stator bore, make rotor in assembling process, keep the 1-2mm distance with stator all the time, effectively avoided scratching of rotor and stator core.
The utility model adopts vertical assembling when motor assembles, utilize guided plate, relies on the deadweight of medium-sized rotor of permanent-magnetic power generator to make generator amature directly enter into generator unit stator inside, need not to press-fit.
Beneficial effect:
The utility model has the advantage of that guided plate is simple in structure, easy to operate, the generation of having avoided motor stator and rotor to scratch in the middle size motor assembling has guaranteed the generator various performance parameters, and the material price of guided plate is cheap simultaneously, and purchase easily, reduced the production cost of generator.
