Abstract
The utility model relates to a submersible motor rotor bearing anti-rotation structure which includes a bearing, grooves, fixing cards, a stator, and stator positioning grooves. The submersible motor rotor bearing anti-rotation structure is characterized in that the grooves are arranged on the two sides of an outer ring of the bearing and are arranged in symmetry by taking a central line of the bearing as a reference; the stator fixing grooves are arranged on the two sides of an inner wall of the stator, and are corresponding to the grooves; the fixing cards are embedded into the grooves and the stator fixing grooves, so the bearing and the stator are connected into an entire body, and consequently the motor structure becomes more perfect, the assembly is more reasonable, the performance is more reliable, and the eddy magnetism phenomenon in the operation of the motor is avoided.
Description
Technical field
The utility model relates to the petroleum pump machine field, particularly a kind of submersible electric machine with oil rotor bearing anti-rotation structure.
Background technology
At present, in known submersible electric pump internal structure, owing to its architectural feature of carefully growing; Its inside is provided with some small machines, all will be provided with bearing in the two ends of rotor of some small machines, like this stator of may command small machine and the air gap between rotor; Can make stable, the three-phase balance of small machine, when small machine moved, rotor bearing should be inactive state; If rotor bearing and rotor produce synchronously and rotate; The rotor bearing wearing and tearing also can cause bigger injury very greatly and to electromagnetic wire so, generally all adopt expansion controlling ring-shaped insert and elastic card structure for preventing that it from rotating, but these all exist the deficiency of assembling difficulty, anti-rotation weak effect.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of submersible electric machine with oil rotor bearing anti-rotation structure, and it processes two symmetrical draw-in grooves respectively on both sides, rotor bearing outer ring; On this draw-in groove, set out two fixedly cards then more respectively; Rotor bearing material selection stainless steel forging molding, and adopt ion nitriding technology to strengthen its resistance to wear, and can overcome submersible electric machine with oil and when operation, do not produce the whirlpool magnetic phenomenon; So just overcome above-mentioned drawback, efficiently solved a difficult problem.
The utility model solves technical scheme that its technical problem adopts: a kind of submersible electric machine with oil rotor bearing anti-rotation structure; It comprises: bearing, draw-in groove, fixedly card, stator, stator location notch; It is characterized in that: said draw-in groove is located at the bearing outer ring both sides; It is symmetrical each other to be as the criterion with bearing axis, and described stator location notch is located at the stator inner wall both sides respectively, and corresponding with described draw-in groove; Described fixedly card embeds respectively in draw-in groove, the stator location notch, makes bearing, stator connect into an integral body.
The beneficial effect of the utility model is: design science is reasonable, and cost of manufacture is low, and Nover practical makes electric machine structure more perfect, and it is more reasonable to assemble, more reliable performance, the phenomenon of generation whirlpool magnetic when having avoided the motor operation.
