The tradition electric drill uses brush direct current motor, and its carbon brush has certain length, and fixedly wear extent is arranged, life time is limited, generally is about 30 hours, and dc brushless motor of the present utility model does not have the carbon brush restriction life-span, electrical machinery life can reach 20,000 hours, reduces environmental pollution.
Dc brushless motor can freely be realized the both forward and reverse directions rotation, and the reliability height is avoided technological damage.
A kind of rechargeable non-carbonate electric drill comprises drill chuck, speed regulator, gear reduction box, motor, casing, positive and negative change-over switch, gauge tap, driving governor, battery, and motor adopts dc brushless motor.
Rechargeable non-carbonate electric drill constitutes the pistol type profile.
Described drill chuck, speed regulator, gear reduction box connect and compose the front portion of the rechargeable brushless electric drill of pistol type successively.
Described dc brushless motor adopts the XB36-3712-01NN model.
Described drill chuck, speed regulator, gear reduction box, the XB36-3712-01NN dc brushless motor is installed in the front end of casing in order, drill chuck is positioned at foremost, and speed regulator is after drill chuck, and gear reduction box is after speed regulator, dc brushless motor is after gear reduction box, and dc brushless motor is packed in the casing.
Described positive and negative change-over switch, gauge tap, driving governor, battery is in the lower handle part of casing, positive and negative change-over switch, gauge tap, driving governor, battery are arranged downwards in order, positive and negative change-over switch is topmost, gauge tap is below positive and negative change-over switch, and driving governor is below gauge tap, and battery is positioned at foot.
Described battery adopts TunePower or dry cell.
Described battery connects dc brushless motor and positive and negative change-over switch with electric wire or contact pin.
Beneficial effect
Rechargeable non-carbonate electric drill of the present utility model reaches the purpose of improvement with dc brushless motor and Drive and Control Circuit thereof.The efficient of dc brushless motor has 80%, has only 20% electric energy loss, saves battery electric quantity greatly, and battery can prolong 4 times towards saturated back service time, reaches 1 hour, saves electric energy.Rechargeable non-carbonate electric drill of the present utility model can be widely used in the electric drill field of power tools.
Description of drawings
Fig. 1 is the assembly structure figure of the brushless electric drill of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the concrete enforcement example of the brushless electric drill of the utility model is described in further detail.
Fig. 1 is the assembly structure figure of the brushless electric drill of the utility model
As shown in the figure, the drill chuck 1 of the rechargeable brushless electric drill of the utility model, speed regulator 2, gear reduction box 3, XB36-3712-01NN dc brushless motor 4, casing 5, positive and negative change-over switch 6, gauge tap 7, driving governor 8, battery 9.
Rechargeable brushless electric drill comprises drill chuck 1, speed regulator 2, gear reduction box 3, motor 4, casing 5, positive and negative change-over switch 6, gauge tap 7, driving governor 8, battery 9.Motor 4 adopts dc brushless motor, and model is XB36-3712-01NN.
Rechargeable brushless electric drill constitutes the pistol type profile.
Speed regulator 2, gear reduction box 3, motor 4 adopt usual manner to connect.
Drill chuck 1, speed regulator 2, gear reduction box 3, XB36-3712-01NN dc brushless motor 4 is installed in the front end of casing 5 in order, drill chuck 1 is positioned at foremost, and speed regulator 2 is after drill chuck 1, and gear reduction box 3 is after speed regulator 2, dc brushless motor 4 is after gear reduction box 3, and dc brushless motor 4 is packed in the casing 5.Drill chuck 1, speed regulator 2, gear reduction box 3 connect and compose the front portion of the rechargeable brushless electric drill of pistol type successively.
Positive and negative change-over switch 6, gauge tap 7, driving governor 8, battery 9 is in the lower handle part of casing 5.Positive and negative change-over switch 6, gauge tap 7, driving governor 8, battery 9 are arranged downwards in order.Positive and negative change-over switch 6 is topmost, and gauge tap 7 is below positive and negative change-over switch 6, and driving governor 8 is below gauge tap 7, and battery 9 is positioned at foot.Positive and negative change-over switch 6, gauge tap 7 adopt usual manner control.
Battery 9 adopts TunePower.Battery 9 usefulness electric wires or contact pin connect dc brushless motor 4 and positive and negative change-over switch 6.
Substitute original brush direct current motor with energy-efficient XB36-3712-01NN dc brushless motor, volume is identical, about efficient doubles, guarantee 3 times of saves energy, extended to 36 minute by original 8 minutes the service time of once charging of battery, the user uses convenient, and saves a large amount of electric energy.
Motor is limited by gear-box intensity, bearing mainly service life service life, normal service life was at 20,000 hours, and the brush direct current motor of former use is determined by carbon brush service life, have only half service life about 30 hours, cause a large amount of electric drills under the intact situation of main components, to be scrapped, consumed a large amount of metal and chemical materials.
