Abstract
The utility model relates to a stator frame for a generator, which comprises a wainscot. The utility model is characterized in that the inner side of the wainscot is fixedly provided with a rib plate on which a circular comb-typed plate is fixedly arranged; the circular comb-typed plate is tightly fixed with an upper and a lower tooth-typed press plate on which an adjusting bolt is arranged; the rib plate is fixedly provided with a splint on which a positioning rib splint is arranged; while the positioning rib splint is fixedly provided with a positioning rib, and a stator iron core is arranged on the inner side of the circular comb-typed through the positioning rib and the positioning rib splint. The utility model has the advantages of not only ensuring the axial rigidity of the stator frame and an abundant cooling space between the stator metal core and the frame, but also having a leading effect on cooling air, thus greatly reducing the resistance of cooling air and improving the cooling effect of the motor. In addition, the utility model has the advantages of simple structure and reasonable design, etc.
Description
Technical field
The utility model belongs to machine field, particularly relates to a kind of electricity generator stator stand.
Background technology
At present, in the manufacturing and designing of motor, for operating efficiency and the useful life that guarantees motor, each part requirement to motor is more and more stricter, out frame is to be related to the operating efficiency of motor and an important component part in useful life in the parts of motor, the out frame a large amount of heat that motor produces in the running that whether can well leave is a sign that detects out frame.Existing out frame structure comprises: wallboard, layering is welded with upper ring plate, middle ring flat-plate and lower ring plate in wallboard, connect by gusset between each laminate, this structure has following deficiency: the connection between each parts can not well guarantee the axial rigidity of support; Owing to when motor rotation, can produce a large amount of heat energy, by the heat radiation of the ventilation hole on the intermediate plate, this radiating mode also can not satisfy the cooling cooling of motor far away, causes motor that superheating phenomenon often takes place, influence the normal operation of motor, even accidents such as burning machine, fire can take place; Structure can not effectively be controlled the distortion of diameter on circularity and size of stator core in addition, can not make the stator core of tight winding obtain better concentricity.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, axial rigidity is strong, the motor stator support of good cooling results
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of electricity generator stator stand, include wallboard, it is characterized in that: the inboard at wallboard is fixed with gusset, be fixed with annular pectinate plate on gusset, annular pectinate plate is fastened with tooth support up and down by stretching screw, on the tooth support conciliation bolt is being installed down, on gusset, be fixed with supporting plate, on supporting plate, be fixed with the positioning bar tray, on the positioning bar tray, be fixed with positioning bar, by positioning bar and positioning bar tray stator core is installed in the inboard of annular pectinate plate.
The utility model can also adopt following technical measures:
The gusset that the inboard of described wallboard installs is a box type gusset, and box type gusset is V-shape.
Have dovetail slot on the described positioning bar tray.
Advantage and the good effect that the utlity model has are: form because wallboard adopts steel plate to roll, replaced the structure of existing several roads ring flat-plate and gusset, effectively guaranteed the axial rigidity of out frame; Be fixed with in the inboard of wallboard and be V-shape box type gusset, on box type gusset, be welded with annular pectinate plate, the annular pectinate plate is fastened with tooth support up and down by stretching screw, on the tooth support conciliation bolt is being installed down, on gusset, be welded with supporting plate, on supporting plate, be welded with the positioning bar tray, on the positioning bar tray, be fixed with positioning bar by dovetail slot, inboard at annular pectinate plate is equipped with stator core by positioning bar and positioning bar tray, thereby the utility model can guarantee that sufficient cooling space is arranged between stator core and the support, and cooling air is also had guide effect, greatly reduce the windage of cooling air, improved the cooling effect of motor.The utility model is V-shape with box type gusset, make it radially have certain elasticity, this buoyancy effect can allow the radial expansion of stator core, thereby prevent the distortion of stator core axial twist, also can the stator core that closely twines is coaxial fixing on the throne, make stator core obtain better concentricity, and the stator core diameter is being controlled aspect circularity and the size distortion, be convenient to support and draw together circle, also strengthened simultaneously the rigidity of support shell, better prevent outside hydraulic pressure, and effectively prevent the vibration of stator core.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure: 1-wallboard; 2-gusset; 3-annular pectinate plate; 4-supporting plate; 5-tray; 6-positioning bar; 7-stator core; 8-tooth support; 9-stretching screw; 10-conciliation bolt.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, be welded with box type gusset 2 rolling the inboard that forms wallboard 1 by steel plate, box type gusset is V-shape, this box type gusset not only can guarantee that the air gap between out frame and the stator core 7 is even, making has cooling space more fully, but also have guide effect, and greatly reduce the windage of cooling air, improved the cooling effect of motor; Radially has certain elasticity in addition, this buoyancy effect can allow the radial expansion of stator core 7, thereby prevent stator core to be subjected to excessive thermal stress between stator core and support and the axial twist distortion, also can the stator core that closely twines is coaxial fixing on the throne, make stator core obtain better concentricity, and the stator core diameter is being controlled aspect circularity and the size distortion, be convenient to support and draw together circle, also strengthened simultaneously the rigidity of support shell, prevented that better outside hydraulic pressure from effectively preventing the vibration of stator core; On box type gusset 2, be welded with annular pectinate plate 3, annular pectinate plate 3 tightens intrinsic tooth support 8 up and down, the annular pectinate plate is kept axial pressing force unshakable in one's determination with stretching screw 9 generations of fastening nut, on the tooth support conciliation bolt 10 that is used for adjusting the stator core tightness is being installed down, on box type gusset 2, be welded with supporting plate 4, on supporting plate, be welded with positioning bar tray 5, the positioning bar tray is fixed with positioning bar 6 by dovetail slot, by positioning bar and positioning bar tray stator core is installed in the inboard of annular pectinate plate 3.
