Fig. 1 is the part sectional drawing of monophase machine in the past, and Fig. 2 is the exploded view of monophase machine shown in Figure 1, and as shown in the figure, monophase machine in the past includes the inboard of casing 1 of the inner space of opening and fixing stator 2; The inboard of stator 2 is provided with the inner peripheral surface of stator 2 and is keeping certain distance, the rotor 3 that can be rotated; The central part of its rotor 3 is inserted with rotating shaft 4; Bearing 11 is being set on the both side ends of rotating shaft 4, and its bearing is fixing by casing 1 and guiding fan sheet 8, makes rotating shaft 4 be rotated.
Being provided with the AC current conversion that will supply with at the upside of rotor 3 is the commutator-rectifier 5 of DC electric current; The both sides of commutator-rectifier 5 are provided with the outside of commutator-rectifier 5 is flexible and contact, give commutator-rectifier 5 provide power supply and and a pair of carbon brush 6 of rotating shaft 4 vertical direction formation; Carbon brush 6 comprises carbon-point 12, carbon-point frame 13, carbon brush holder 14, spring 15.
The downside of the casing 1 of motor is being fixed the bearing 11 that guiding fan sheet 8 fixes supporting rotating shaft 4, is fixedly installing the fan 9 of introducing air on the rotating shaft 4 below guiding fan sheet 8, and fan 9 below in conjunction with fan cover 10.
Carbon brush for electric machine 6 in the past is made of carbon-point 12, carbon brush holder 13, carbon brush holder 14, spring 15, and carbon brush holder 13 and carbon brush holder 14 independent formation assemble again, and the material of carbon brush holder 13 is copper materials, therefore, and the complex manufacturing technology of carbon brush 6, cost height
Summary of the invention
The present invention provides a kind of commutator-rectifier both sides that are arranged on, carbon-point frame, the integrally formed carbon brush structure of carbon brush holder for solving the technical problem that exists in the above-mentioned technology.
The technical scheme that the present invention takes for the technical problem that exists in the above-mentioned technology of solution is:
A kind of carbon brush structure among the present invention comprises the carbon-point with the commutator-rectifier Elastic Contact; The carbon-point frame that contains carbon-point; Be fixed on the carbon brush holder on the casing; Be arranged on the spring of carbon-point frame blind end inside; The integrally formed carbon-point supporting construction of carbon-point frame and carbon brush holder; Be formed with the multiple tracks radiating groove on the carbon-point supporting construction; The carbon-point supporting construction adopts hard plastic injection molding integrally formed.
Advantage and good effect that the present invention has are: a kind of carbon brush structure of the present invention, integrally formed carbon-point supporting construction, the carbon-point frame adopts the rigid plastics identical with carbon brush holder, and integrated through injection molding forms, reduced component costs, simplify manufacture craft, on the carbon brush supporting construction, be formed with the multiple tracks radiating groove, improved the thermal diffusivity of carbon brush.
