Abstract
The utility model discloses a serrated pressure plate for compressing punching pieces in a generator. The serrated pressure plate comprises a fan-shaped serrated pressure plate body, wherein a plurality of tension holes used for compressing the punching pieces are uniformly distributed in the surface of the fan-shaped serrated pressure plate body; positioning grooves which are distributed uniformly are formed on the outer side of the serrated pressure plate body; a plurality of pressure fingers which are arranged radially are welded on the inner side of the serrated pressure plate body; the positioning grooves are trapezoidal grooves with wide bottoms and narrow openings; and the pressure fingers are welded on the inner end edge of the serrated pressure plate body and are higher than the height of one side of the serrated pressure plate body. The utility model has the characteristics that the serrated pressure plate is reasonable in structure, low in manufacturing cost and convenient to install, the use efficiency of the generator can be improved and the like.
Description
Technical field
The utility model relates to the tooth support that is used to compress punching in a kind of generator, belongs to mechanism of power generation technology for making field.
Background technology
The critical piece of generator comprises rotor and stator or the like; Rotor wherein is to be formed through punching out by silicon steel sheet material, is referred to as punching, and these punchings need the tension of blocks of superimposed back to form a rotor; But between punching, need sandwich tooth support; So that guarantee the normal use of rotor structure, therefore, use this tooth support will play very crucial effect for the performance of whole rotor and the serviceability of generator.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that prior art exists, and provides a kind of rational in infrastructure, is used to compress the tooth support of punching in the generator easy for installation.
The purpose of the utility model is accomplished through following technical scheme; It comprises the tooth pressure plate body of one one-tenth fan shape; Its surface is evenly equipped with a plurality of tension holes that are used to compress punching; The outer side edges of said tooth pressure plate body is provided with the location notch that is uniformly distributed with, and is welded with the end finger of many radial arrangement on the inner side edge.
Described location notch is the young dovetail groove of bottom width; Described end finger is welded on the inner limit of tooth pressure plate body, and exceeds the height of tooth pressure plate body one side.
The utlity model has rational in infrastructurely, easy for installation, low cost of manufacture can improve the characteristics such as service efficiency of generator.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model.
Fig. 2 is the syndeton sketch map of the described tooth support physical culture of the utility model end finger.
Embodiment
To combine accompanying drawing that the utility model is done detailed introduction below: shown in Figure 1; The tooth support that is used to compress punching in the described generator of the utility model; It comprises the tooth pressure plate body 1 of one one-tenth fan shape, and its surface is evenly equipped with a plurality of tension holes 2 that are used to compress punching, and the outer side edges of said tooth pressure plate body 1 is provided with the location notch 3 that is uniformly distributed with; Be welded with the end finger 4 of many radial arrangement on the inner side edge, see shown in Figure 2.
Location notch shown in the figure is the young dovetail groove of a bottom width, and its structure is corresponding with the shape of punching basically; Described end finger 4 is welded on the inner limit of tooth pressure plate body 1, and exceeds the height of tooth pressure plate body 1 one sides, makes when it is interposed between the punching, can form the certain interval between the punching.It can compress punching, guarantees that the electric property after the punching assembling keeps good.
