Abstract
The special-shaped sliver rotor of a kind of submersible electric machine with oil, comprise rotor core, the rotor bar that constitutes circumferential arrangement and the installation end ring and the rotor punching at sliver two ends, the cross section that is characterised in that the sliver mid portion is a profiled-cross-section, and the cross section, termination of sliver two ends and end ring junction is circular.Superiority of the present utility model is: 1. need not profiled holes is processed in the sliver hole of end ring, making end machining is that the special-shaped sliver of circle and the combination of end ring are easy to riveting processing, solved the difficult problem when special-shaped sliver is connected with end ring junction riveting dexterously, improved the rotor working (machining) efficiency and saved man-hour; 2. owing to adopted special-shaped sliver rotor during design of electrical motor, rotor performance can have been performed to and extremely, improved detent torque and runnability, for reaching world-class level, efficient submersible electric machine with oil lays a good foundation; 3. have cost performance preferably, produce market has competitiveness preferably; 4. market prospects are boundless, and can satisfy demand for exports.
Description
(1) technical field:
The utility model relates to a kind of petroleum machinery, the special-shaped sliver rotor of particularly a kind of submersible electric machine with oil.
(2) background technology:
At present, existing submersible electric machine with oil rotor bar is round cross section structure all, does not make full use of the space on rotor, is unfavorable for that motor given play to high performance, has so just limited the development need of submersible electric machine with oil.
(3) summary of the invention:
The purpose of this utility model is to design the special-shaped sliver rotor of a kind of submersible electric machine with oil, and it is overcome above-mentioned shortcoming, is a kind of practical rotor that novel sliver is housed.
The technical solution of the utility model: the special-shaped sliver rotor of a kind of submersible electric machine with oil, comprise rotor core, the rotor bar that constitutes circumferential arrangement and the installation end ring and the rotor punching at sliver two ends, the cross section that is characterised in that the sliver mid portion is a profiled-cross-section, and the cross section, termination of sliver two ends and end ring junction is circular.
Special-shaped sliver cross section in the above-mentioned said special-shaped sliver rotor can be the trapezoidal of circular arc for big or small limit, also can be trapezoidal, fan-like pattern, pyriform, T shape.
Using method of the present utility model with the course of work is: end machining is connected for circular special-shaped sliver carries out riveting with round-meshed end ring and rotor punching, constitutes motor rotor core.
Superiority of the present utility model is: 1, need not profiled holes is processed in the sliver hole of end ring, making end machining is that the special-shaped sliver of circle and the combination of end ring are easy to riveting processing, solved the difficult problem when special-shaped sliver is connected with end ring junction riveting dexterously, improved the rotor working (machining) efficiency and saved man-hour; 2, owing to adopted special-shaped sliver rotor during design of electrical motor, rotor performance can have been performed to and extremely, improved detent torque and runnability, this technology reaches world-class level and lays a good foundation for developing efficient submersible electric machine with oil from now on; 3, because the motor performance height makes the client reduce the expense of operation, have cost performance preferably, produce market has competitiveness preferably; 4, market prospects are boundless, and can satisfy demand for exports.
(4) description of drawings:
Accompanying drawing 1 is the special-shaped sliver rotor overall structure schematic diagram (wherein 1-a is a front view, and 1-b is the side parting face view of 1-a) of the related a kind of submersible electric machine with oil of the utility model.
Accompanying drawing 2 is the special-shaped sliver overall structure schematic diagram (wherein 2-a is a front view, and 2-b is the side parting face view of 2-a) in the special-shaped sliver rotor of the related a kind of submersible electric machine with oil of the utility model.
Wherein: 1 is rotor core, and 2 is special-shaped sliver, and 2a is the sliver termination, and 3 is end ring, and 3a is end ring hole (combining used with end ring for the sliver termination), and 4 is rotor punching.
(5) embodiment:
Embodiment: the special-shaped sliver rotor (seeing Fig. 1-3) of a kind of submersible electric machine with oil, comprise rotor core 1, the rotor bar 2 that constitutes circumferential arrangement and the installation end ring 3 and the rotor punching 4 at sliver two ends, the cross section that is characterised in that sliver 2 mid portions is that big or small limit is that (see Fig. 2-b), Fig. 2-b) (is seen for circular in the 2a cross section, termination of sliver 2 two ends and end ring 3 junctions for the trapezoid cross section of circular arc.
Claims (2)
1, the special-shaped sliver rotor of a kind of submersible electric machine with oil, comprise rotor core, the rotor bar that constitutes circumferential arrangement and the installation end ring and the rotor punching at sliver two ends, the cross section that is characterised in that the sliver mid portion is a profiled-cross-section, and the cross section, termination of sliver two ends and end ring junction is circular.
2, according to the special-shaped sliver rotor of the said a kind of submersible electric machine with oil of claim 1, it is characterized in that the special-shaped sliver cross section in the said special-shaped sliver rotor can be the trapezoidal of circular arc for big or small limit, also can be trapezoidal, fan-like pattern, pyriform, T shape.
