Abstract

The utility model discloses a generator stator core's fixed knot constructs, stator are 6 towards the piece and piece together, locate to have a flange structure at the stator towards the center of piece excircle, its characterized in that: after the stator was accomplished towards the piece pressure equipment, six cramps firmly welded with the stator clamping ring near setting, cramp with six alternate flanges, and the stator adopts 30 degrees angle modes of dislocation to put the piece towards the piece adjacent layer for stator core has 12 flanges, the impress in -process of frame of ribbon winding stator core, and 12 flanges installations set up in the barrel in 12 grooves of frame, constitute stator core's fixed knot constructs. The utility model discloses a flange structure has replaced the rib in the frame, directly inlays on the barrel, prevents that stator core from taking place relative the rotation with the frame when the motor moves to for generator safety, reliably the operation provide the guarantee. The utility model discloses an advantage be: 1, the commonality is good, 2, simple structure, 3, it is convenient to make.

Description

A kind of fixed structure of stator core

Technical field

This utility model relates to the structure of a kind of generator stator core internal stator punching, is specifically related to the fixed structure of a kind of stator core.

Background technology

In the design process of conventional electric generators stator core, stator punching, after having been press-fited by stator punching, is fixed by stator core by stator pressing ring and cramp, and then on support, holding screw is installed in boring, is fixed on support by band wound stator iron core.When electromotor long-play, stator core temperature raises, and stator punching can occur axial expansion, and after shutdown, the gap between punching increases, it is possible to occur to loosen.When motor overload, stator core is owing to being relatively rotated with support by the great force of electromagnetic wire in groove.Therefore devise the structure of a kind of stator punching, make the problems referred to above be efficiently solved.

Summary of the invention

The purpose of this utility model is to provide the fixed structure of a kind of stator core, this fixed structure to prevent stator core from relatively rotating with support when motor runs, thus provides guarantee for engine health, reliably operation.

The technical solution adopted in the utility model is: the fixed structure of a kind of stator core; stator punching is 6 spellings; there is a flanged structure center at stator punching cylindrical unlike general stator punching; this flanged structure can utilize cramp, prevents electromotor operationally, and stator core raises due to temperature; stator punching generation axial expansion; producing gap after shutting down cooling and internal loosening occurs, this flanged structure instead of the rib in support, is directly embedded on cylinder；It is characterized in that: after stator punching has press-fited, six cramps are closely against with alternate six flanges together with, by cramp and stator pressing ring firm welding；During by band wound stator iron core press-in support, by the cylinder of 12 existing 12 grooves of flange press-in, define the fixed structure of stator core.

The advantage of this utility model patent is: 1, versatility is good；2, simple in construction；3, easily manufactured.

Detailed description of the invention

As shown in Figure 1 and Figure 2, this utility model is such to work and enforcement, the fixed structure of a kind of stator core, after stator punching has press-fited, 6 cramps 1 are closely against with alternate 6 flanges 2 together with, by cramp and stator pressing ring firm welding；During by band wound stator iron core press-in support, 12 flanges 2 are pressed in the cylinder 3 of existing 12 grooves, define the fixed structure of stator core.

Stator punching designed by this utility model is such, for the stator punching that a circle is 6 spellings, on the basis of original stator punching, increase by an outward flange in the center of stator punching cylindrical, owing to using 30 degree of angle modes of adjacent layer to carry out pendulum, so stator core just has 12 row flanges, it is evenly distributed on the outer ring of stator core, these 12 flanges are then to replace traditional rib, when band wound stator iron core press-in support, in the cylinder of 12 grooves that press-in has processed, form a kind of fixed structure.Together with wherein 6 alternate flanges are closely against with 6 cramps, by cramp and stator pressing ring firm welding.

The stator core of generator; it is a kind of flanged structure utilizing stator punching; match with the cylinder on cramp and support; thus prevent electromotor operationally stator core due to the axial expansion of stator punching; produce gap after shutting down cooling and make to occur inside it to loosen; again owing to being relatively rotated with support by the great force of electromagnetic wire in groove, cause huge destruction to electromotor.

Claims (1)

1. a fixed structure for stator core, stator punching is 6 spellings, has a flanged structure in the center of stator punching cylindrical；It is characterized in that: after stator punching has press-fited, six cramps and alternate six flanges are against setting, cramp firmly welds with stator pressing ring, stator punching adjacent layer uses 30 degree of angle modes of dislocation to carry out pendulum, stator core is made to have 12 flanges, during band wound stator iron core press-in support, 12 flanges are mounted in the cylinder of 12 grooves of support, constitute the fixed structure of stator core.
