The electric brush assembly connecting structure of motor that vacuum cleaner is used
Technical field of the present invention
The present invention relates to the motor that vacuum cleaner is used, particularly brush case and support are made of one, and the syndeton of motor brush assembly.
Technical background of the present invention
Generally speaking, the motor that vacuum cleaner is used, its rotating shaft is installed in the rotor, utilizes the impeller rotation that is connected with rotating shaft one end to produce suction, and inner air is arranged to the outside, simultaneously utilized air pressure inside to be lower than the principle of external pressure again, the air that periphery is contained dust and foul sucks in, and simultaneously, by the control of dust cleaner foul is carried out control of dust, clean air is discharged to the outside, finishes the contaminated space of cleaning.
The motor that the conventional vacuum cleaners of finishing this work is used is illustrated in conjunction with the accompanying drawings below.
The motor brush assembly partial sectional view that Fig. 1 uses for traditional vacuum cleaner.The motor brush assembly that Fig. 2 uses for traditional vacuum cleaner connects side view.The motor brush components side view that Fig. 3 uses for traditional vacuum cleaner.
As shown in Fig. 1 to Fig. 3, the motor that conventional cleaners is used is produced rotating mechanism, is connected with rotating mechanism by power supply, and the several sections such as vacuum mechanism that produce suction because of its rotation are formed.
Rotating mechanism is made up of rotating shaft (5), stator (6), support (8) and brush assembly of electric.Upper bearing (metal) (1), commutator (2), rotor (3) and lower bearing (4) are installed on the rotating shaft (5).Stator (6) is installed in the outer peripheral face of rotor.Top chock (7) being installed on the support (8), upper bearing (metal) (1) is installed in it, is stator below.Brush assembly of electric then in the both sides of commutator (2) respectively with commutator sliding-contact, supply power, and be connected with the both sides of screw with support (8).
The vacuum generating mechanism is made up of impeller chimney (9), impeller (10), fixture (11) and bearing (13).Impeller (10) is connected with rotating shaft (5), in the impeller inner rotation, produces suction.Fixture (11) is fixed on impeller chimney (9), impeller (10) on the rotating shaft respectively, and bearing (13) has step (12), connects rotating shaft (5) rotation for inserting lower bearing (4).
Between bearing (13) and support (8), stator (6) is installed, and is respectively equipped with spliced eye (14a, 14b, 14c), can use connecting bolt (14) to pass, above-mentioned support (8), stator (6) and bearing (13) are fused.On the support that is provided with spliced eye (14a) (8) two sides, be provided with spliced eye (15a), connecting bolt (15) connects brush assembly of electric.
Brush assembly of electric is made up of brush (16), brush carrier (17) and brush case (19).Brush carrier (17) center brush (16) one ends and commutator (2) sliding-contact, the other end is by spring-loaded.In brush case (19) two sides, be provided with bearing spliced eye (15b), so that above-mentioned brush carrier (17) is connected on the above-mentioned support (8) with set bolt (15).
The motor that adopts the conventional vacuum cleaners of above-mentioned composition mode to use, bearing (1), commutator (2) are installed in top, are rotor (3) and lower bearing below the commutator (2).The bottom is fixed on the inner impeller of impeller chimney (9) on the bearing (13) that passes rotating shaft (5) connection with fixture (11), rotor (3), be positioned at the stator (6) of rotor (3) outer peripheral face and the support (8) on top, place successively, and connected with bracket fixing bolt (14).
