Description
Technical field
[0001] the utility model relates to the efficient NEMA motor stator of a kind of steel plate shell and press-fits combination, is to belong to efficient NEMA steel shell motor to produce stator and be pressed into press-fiting of casing and operation
The fieldMainly be applicable to NEMA motor, generator, electric pump etc.
Background technology
The existing production processes such as efficient NEMA steel shell motor and pump class that comprise, the very thin thickness cost of steel plate shell is low, steel plate shell production process and steel plate shell itself distortion, general endoporus center of circle degree is very low, cause that the field frame assembly centrad is uncontrollable to be not easy to be pressed into very much steel plate shell, production process defective products can occur being pressed into and occur, or still have the end face seam distortion to occur after being pressed into, gas length is large after the motor whole machine installation, electric efficiency is low, output and operating efficiency are also very low, can't realize in batches high yield.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and provides a kind of simple in structure, and cost is low, use simple and easy, the new and effective NEMA steel shell motor stator press-loading combination of increasing work efficiency.
1. the utility model discloses the efficient NEMA motor stator of a kind of steel plate shell and press-fit combination, applicable steel shell motor is produced stator and is pressed into press-fiting of casing and operation.Described a kind of steel shell motor stator press-loading combination: include a kind of steel shell motor stator press-loading combination, include navigation frock (1), compression set press-fits (2), frock support (3), tapering (11) is arranged at the frock bottom that it is characterized in that navigating, top has less than the step of casing internal diameter (12), frock support (3) fluted (31) fixation steel plate shells (4).
2. the efficient NEMA motor stator of described steel plate shell press-fits combination, and the frock (1) that it is characterized in that navigating is done by heat treated 45# steel, and navigation frock (1) upper height (H1) is higher than the spacing height 1-2mm in motor stator bottom.
3. the efficient NEMA motor stator of described steel plate shell press-fits combination, it is characterized in that the fluted fixation steel plate shell of frock support, top bar that internal diameter and casing external diameter match and, endoporus is greater than the outer 0.3-0.5mm of stator, endoporus height (H3) is higher than navigation frock (1) height overall.
Description of drawings
Fig. 1 the utility model structure navigation frock view;
Fig. 2 the utility model structure press-fits view;

Among the figure: 1. navigation frock, 2. stator press-loading, 3. frock support, 4. steel plate shell, 5. motor stator, 11. taperings, 13. steps, 31. grooves, H1. upper height, the spacing height of H2., H3. endoporus height.
Embodiment
Now by reference to the accompanying drawings, the utility model embodiment is described in detail in detail:
As shown in the figure, the combination of steel shell motor stator press-loading includes navigation frock (1), compression set press-fits (2), frock support (3), tapering (11) is arranged at the frock bottom that it is characterized in that navigating, the centre is that excessive cylinder internal diameter section is the same with the casing internal diameter size, top has less than the step of casing internal diameter 0.5～1.0mm (13), highly (H1); Navigation frock (1) is done by heat treated 45# steel, and navigation frock (1) upper height (H1) is higher than the spacing height in motor stator bottom (H2) 1-2mm; The fluted fixation steel plate shell of frock support, the internal diameter of topping bar matches with the casing external diameter, and endoporus is greater than stator outer diameter 0.3-0.5mm, and endoporus height (H3) is higher than navigation frock (1) height overall.
Specifically such as Fig. 4 example:
A. it is fixing steel plate shell (4) to be placed on the groove (31) of frock support (3);
B. navigation frock (1) is enclosed within on the steel plate shell (4) that fixes, horizontal direction is placed;
C. motor stator (5) is put leading-out terminal in order, is placed on the navigation frock (1);
D. compression set press-fits (2) and covers motor stator (5) top, and keeps with one heart vertical;
E. press-fit with vertical compression set of hydraulic press;
F. the frock of navigating (1) under pressure, navigation frock (1) is coincide in the steel plate shell seam, full circle steel plate shell internal diameter; Motor stator (5) just can be along with navigation frock (1) is pressed in the steel plate shell (4); And directly be press-fit into place; Since arrange the navigation frock (1) step (13) highly (H1) be higher than the spacing height 1-2mm in motor stator bottom, the navigation frock (1) break away to frock support (3); Further full circle steel plate shell bottom seam; Motor stator (5) is pressed in the steel plate shell, and steel shell motor stator press-loading operation is finished.
It is a kind of simple in structure that the utility model provides, easy to operate, guarantee steel shell motor stator and the same circularity of both ends of the surface seam, and when being pressed into motor stator, realize full circle steel plate shell inner cylinder face, circle concentricity in improving, reduce gas length, can realize the next procedure standardized production, increase work efficiency, the rate of reducing the number of rejects and seconds, reach the purpose of consumption reduction volume increase, be applicable to steel shell motor, the batch production of NEMA motor of common production and streamline.
