Abstract
The utility model discloses a motor rotor, which comprises a rotor body (1), wherein a rotor seat (2) and a supporting body (3) which cling to the inner side wall of the rotor body (1) are arranged on the groove bottom of the rotor body (1), and a shaft hole (5) is arranged at the center of the rotor seat (2); a gap (6) is arranged between the rotor seat (2) and the supporting body (3), and the width of the gap (6) is 4-8mm; and a reinforced seat (4) for supporting the rotor body (1) is arranged above the rotor seat (2) and the supporting body (3). The utility model has the characteristics of simple manufacture, short production cycle and good insulating effect, and the utility model is safe and convenient to use.
Description
Technical field
The utility model relates to a kind of rotor, belongs to field of mechanical technique.
Background technology
The rotor of micro-machine generally comprises rotor block, be located in the rotating shaft on the rotor block and be arranged on permanent magnet on the rotor block.Existing rotor shaft is made by metal material, and rotor block then generally adopts cast aluminium to make, and rotor block takes place often conduct electricity to rotating shaft and make the charged situation of rotating shaft, uses more dangerous.At present, though insulation processing with the rotating shaft impregnated insulating paint is also arranged, it is comparatively complicated that the insulation processing of impregnated insulating paint exists technology, and the production cycle is long, the more unfavorable problem of insulation effect.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of rotor.The utlity model has and make the characteristics simple, with short production cycle, that insulation effect is good, the utility model is safe and convenient to use.
For solving the problems of the technologies described above the technical solution of the utility model: a kind of rotor, comprise rotor block, the bottom land of rotor block is provided with rotator seat and the supporter of being close to the rotor block madial wall; The rotator seat center offers axis hole, is provided with the gap between rotator seat and the supporter.
In the above-mentioned rotor, the width in described gap is 4～8mm.
In the aforesaid rotor, the top of described rotator seat and supporter is provided with reinforced seat.
The beneficial effects of the utility model: compared with prior art, the utility model has the rotator seat in gap at setting of rotor block bottom land and rotor body, and rotating shaft is located in the axis hole of rotator seat; When the rotor block of motor is rotated by the effect of magnetic force, rotator seat on the rotor block drives rotating shaft and rotates, because there are the gap in rotator seat and rotor block, has when rotor block under the situation of electricity, guaranteed the insulation of rotating shaft greater than the gap of its creepage distance, the utility model is safe in utilization.In addition, the applicant obtains when gap during at 4～8mm by repeated screening, comparison, summary, and it can guarantee the stable operation of rotor, can make again to the utlity model has desirable insulation effect; In addition, the utility model is provided with reinforced seat above rotator seat and supporter, and reinforced seat is supported on rotor block inside, and rotor block is played booster action.

Fig. 2 is a cutaway view of the present utility model;
Fig. 3 is a stereogram of the present utility model;
Fig. 4 is the stereogram of rotator seat of the present utility model.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Embodiment
Embodiment.A kind of rotor, shown in accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, include rotor block 1 and the permanent magnet 8 that is arranged on the rotor block, the bottom land of described rotor block 1 is provided with rotator seat 2 and the supporter 3 of being close to rotor block 1 madial wall, the shape of rotator seat 2 is as shown in Figure 4 attached, and rotator seat 2 centers offer axis hole 5, and axis hole 5 is less than rotor block axis hole 7, rotator seat 2 has four lobate sheet metals, and sheet metal is provided with bolt hole; The shape of rotator seat 2 also can be to have the annulus sheet metal of axis hole or have the rectangular metal sheet of axis hole.The rotating shaft of rotor is located on the rotor block 1 by axis hole 5, and rotator seat 2 and supporter 3 tops are provided with reinforced seat 4, and shown in accompanying drawing 2 and accompanying drawing 3, reinforced seat 4 comprises to be strengthened the bottom surface and be fixed on the ribs of strengthening the bottom surface; Rotor block 1, rotator seat 2, supporter 3 and reinforced seat 4 be from bottom to up to setting gradually, and adopt the mode of casting plastic-steel to be fixed together, and also can adopt bolt; Have gap 6 between rotator seat 2 and the supporter 3,, have when rotor block under the situation of electricity, guaranteed the insulation of rotating shaft greater than the gap of its creepage distance because there are the gap in rotator seat and rotor block; Gap 6 is of a size of 5mm, and when in the scope of gap 6 at 4～8mm, it can guarantee the stable operation of rotor, can make again to the utlity model has desirable insulation effect.
Execution mode of the present utility model is not limited to the foregoing description, all belongs within the protection range of the present utility model in the various variations of making under the prerequisite that does not break away from the utility model aim.
