Abstract
The utility model relates to a power generator with an auxiliary support structure. In the specific implementation, a power generator shell 2 and a stator 4 are fixedly connected through a mechanical structure, a power generator shaft 5 and a rotor 3 are fixedly connected through a mechanical structure, and an inner ring and an outer ring of a bearing 6 are respectively matched with the power generator shaft 5 and the power generator shell 2 and cannot move left and right along the axial direction. An inner hole at the left end of the power generator shell 2 is matched with a spigot of a diesel engine for radial positioning, an inner tapered hole of the power generator shaft 5 is matched with an outer tapered surface of an output shaft 12 of the diesel engine, the power generator is fixed on the diesel engine through tightening a long screw 7, a support plate 8 is sleeved on the tail part of the power generator and is connected with a support seat 10 through a support plate fixing screw 9, and the support seat 10 is connected with a base 14 through a support seat fixing screw 11.
Description
Technical field
The utility model relates to that diesel engine connects with generator in the diesel power generation system, the structure and the means of fixation of generator self.
Background technique
The diesel electric power plant chief component is diesel engine and generator, the employed generator of the utility model is the rare earth permanent magnet iron-core less motor, traditional generator unit stator and rotor are radial air gaps, and rare earth permanent magnet iron-core less motor stator and rotor are axial air-gaps, therefore the axial clearance to rotor has strict restriction, and diesel engine is when work, there is axial float in its output shaft, when the output shaft of diesel engine connects with generator shaft, the most direct result increases the axial float of generator, causes rotor to sweep thorax.How the moment of torsion with diesel engine is delivered on the generator, does not allow the axial float of diesel engine have influence on generator again, be to use the generating of rare earth permanent magnet iron-core less motor the problem that must face.Addressed this problem the way below the common employing in the past: the one, remove the bearing between generator amature and stator, increase rotor and stator shaft orientation design gaps, when axial float is little, can not produce and sweep the thorax phenomenon.But axial clearance increases, and the working efficiency of generator is reduced.The 2nd, keep the bearing between generator unit stator and rotor, stator is connected with body with the output shaft of diesel engine respectively with rotor.Though from ceiling structure system the axial float of rotor.But owing to make and assembly error, the disalignment between generator and the diesel engine increases the load of the output shaft of diesel engine, causes the fracture of diesel engine output shaft when serious.The 3rd, adopt elastic coupling flexible coupling to connect between engine shaft and the generator shaft, vibration, impact and high rotating speed (more than the 3000rpm) owing to diesel engine make seriously descend the working life of coupling.
Summary of the invention
For the influence to generator of the play that solves the diesel engine output shaft, the utility model has solved the problem of diesel engine axial float to the generator influence by improving generator Structure and changing means of fixation to generator.
One, generator Structure.Rotor one end of generator is by bearings, and an end floats.One end of bearing is being housed, bearing restrict rotor two-way moving vertically, the processing dimension that is contained in the part on the axle by control has guaranteed that the axial clearance of rotor and stator reaches the radial clearance at the rotating shaft right-hand member.At the other end of rotor shaft, the internal taper hole on the axle cooperates with the male cone (strobilus masculinus) of engine shaft, and the long bolt by the generator afterbody is strained and fixed, and has both transmitted moment of torsion, has guaranteed the coaxality of diesel engine and generator again.
Two, the means of fixation of generator.The support in generator left side is to cooperate with the boss of diesel engine by the endoporus on the casing to realize, has also guaranteed generator unit stator and the rotor radial clearance in the rotating shaft left side simultaneously, and the right side is the structure that a supplemental support is set at the center of casing.The supplemental support effect is to bear the part weight of motor and the position that do not change the generator center, does not influence the coaxality of diesel engine and generator.
Three, between diesel engine and motor, also have a spline piece, prevent that the shell of generator from rotating with rotor.
The beneficial effects of the utility model are:
1, make the application of rare earth permanent magnet iron-core less motor in diesel electric power plant wider
2, improved the efficient of generator
3, help prolonging the working life of diesel engine and generator
4, simple in structure, cost is low
5, assembly technology is simple
