Abstract
The utility model discloses an electromotor rotor comprising a rotor shell, a rotating shaft, a rotor punching sheet and magnetic tiles, wherein the magnetic tiles are uniformly distributed on an outer periphery of the rotor punching sheet, each spring sheet is arranged between two neighboring magnetic tiles, a sleeve cylinder which is not magnetically conductive is arranged between the rotating shaft and the magnetic tiles, and the magnetic tiles are fixedly connected onto the sleeve cylinder through screws. The electromotor rotor provided by the utility model is characterized in that the sleeve cylinder which is not magnetically conductive is arranged between the magnetic tiles and the rotating shaft, magnetic leakage phenomena can be reduced, the magnetic tiles are fixedly connected onto the sleeve cylinder through the screws, the magnetic tiles can be firmly combined with the sleeve cylinder, and dismounting convenience is realized.
Description
Technical field
The utility model relates to a kind of rotor, particularly a kind of permanent magnet machine rotor.
Background technology
The iron core of existing generator amature is to be overrided to form with rotor punching, again magnetic shoe is fixed on the iron core surface with adhesive glue, dismounting inconvenience.The patent No. provides a kind of rotor for 201120346041.8 Chinese utility model, and its magnetic shoe is arranged on the outer wall of iron core, though the position-limiting action of spring leaf is arranged, magnetic shoe is still stable inadequately in fast rotational, causes generator failure easily.In addition, rotor core and rotating shaft are magnetic conductor, are easy to generate leakage field.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of rotor is provided, and has solved the problem that rotor of the prior art is easy to generate leakage field at work.
For achieving the above object, the technical solution of the utility model is: a kind of rotor, comprise rotor case, rotating shaft, rotor punching and be distributed on magnetic shoe on the rotor punching excircle, be provided with spring leaf between adjacent two magnetic shoes, be provided with non-magnetic sleeve between rotating shaft and the magnetic shoe, magnetic shoe is fixedly connected on the sleeve by screw.
The beneficial effects of the utility model are: non-magnetic sleeve is set between magnetic shoe and rotating shaft, can reduces the leakage field phenomenon, magnetic shoe is fixedly connected on the sleeve by screw, and magnetic shoe is combined with sleeve more securely, dismantles convenient.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is front view of the present utility model.
Among the figure: rotor case 1, rotating shaft 2, rotor punching 3, magnetic shoe 4, spring leaf 5, screw 6, sleeve 7.
Embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.
Embodiment:
As shown in Figure 1 and Figure 2, a kind of rotor, comprise rotor case 1, rotating shaft 2, rotor punching 3 and be distributed on magnetic shoe 4 on rotor punching 3 excircles, be provided with spring leaf 5 between adjacent two magnetic shoes 4, be provided with non-magnetic sleeve 7 between rotating shaft 2 and the magnetic shoe 4, magnetic shoe 4 is fixedly connected on the sleeve 7 by screw 6.
The rotor that the utility model provides arranges non-magnetic sleeve 7 between magnetic shoe 4 and rotating shaft 2, can reduce the leakage field phenomenon, and magnetic shoe 4 is fixedly connected on the sleeve 7 by screw 6, make magnetic shoe 4 more securely with sleeve 7 combinations, dismantle convenient.
