Abstract
The utility model discloses an automatic door brushless direct-current (DC) gear motor comprising a DC brushless motor, wherein the DC brushless motor is fixed at one side of a box body, an automatic door driving rotating shaft is installed at the other side of the box body, a driving gear is fixed on a rotating shaft of the DC brushless motor, a wedge belt is tensioned on the driving gear and a driven gear, a bevel gear is fixed on a shaft of the driven gear and meshed with a reduction gear, the shaft of the reduction gear penetrates through a preset hole in a box cover to be fixedly connected with the automatic door driving rotating shaft together, and the box cover is fixed on the box body. As the driving gear is adopted for directly driving the reduction gear to rotate through the wedge belt, the automatic door brushless DC gear motor is low in energy consumption and noise, and simpler in structure, and can work normally in cold areas.
Description
Technical field:
The utility model relates to technical field of motors, more specifically to controlling the brushless direct-current reducing motor that automatically-controlled door is used.
Background technology:
The automatically-controlled door reducing motor generally is made up of motor, worm gear and worm screw, under automatic door control system and other auxiliary supporting device effect, reaches reducing motor and relies on synchronizing wheel to drag the action that a body is realized open and close.Its weak point is: the domestic general use tin bronze of worm gear and worm screw material is manufactured and formed, and is easy to wear, noise is big, transmission efficiency is low.
Granted publication CN201409044Y, patent No. ZL200920120125.2 disclose a kind of automatically-controlled door brushless direct-current reducing motor, and it uses one-level gear and secondary gear to carry out transmission.Its weak point is: 1, the design gear case extremely bothers, and gear box is big in course of work energy loss, and noise is also big.2, the oily easy freezing in the cold district gear box, causing product can't operate as normal.
The utility model content:
The purpose of this utility model is exactly the deficiency at prior art, and a kind of automatically-controlled door brushless direct-current reducing motor is provided, and it adopts by driven wheel and directly drives the reduction gearing rotation by the wedge band, it is little that energy is economized consumption, noise is little, and structure is more simple, can operate as normal at cold district.
Technology solution of the present utility model is as follows:
A kind of automatically-controlled door brushless direct-current reducing motor, comprise the DC brushless motor, box body is fixed with the DC brushless motor on one side, another side is equipped with automatically-controlled door and drives rotating shaft, is fixed with driven wheel in the rotating shaft of DC brushless motor, and the wedge band is stretched on driven wheel and the driven gear, be fixed with helical gear on the axle of driven gear, helical gear is meshed with reduction gearing, and default hole and automatically-controlled door driving rotating shaft that the reduction gearing axle passes on the lid are fixed together, and lid is fixed on the box body.
Described helical gear is 20 teeth, and reduction gearing is 50 teeth.
Be fixed with the inner ring of bearing on the described reduction gearing axle, be fixed with the inner ring of bearing on the axle of driven gear, the outer ring of bearing is fixed on the lid.
Form fixedly ear on the described box body.
The beneficial effects of the utility model are:
1, it does not adopt secondary gear crossing in gear box, the transmission efficiency height, energy consumption is little, and is compared with prior art energy-conservation about half, noiselessness simultaneously, do not exist yet product cold district can't operate as normal phenomenon.
2, its helical gear is meshed with reduction gearing, and reduction gearing adopts nylon gear, allows engaging piece does not have the gap as far as possible between helical gear and reduction gearing, the infringement of torsion in the time of reducing the DC brushless motor like this and reverse.
Description of drawings:
Fig. 1 is a perspective exploded view of the present utility model
Fig. 2 is a structural representation of the present utility model
Fig. 3 is a schematic perspective view of the present utility model
Among the figure: 1, DC brushless motor; 2, automatically-controlled door drives rotating shaft; 3, box body; 31, solid ear; 4, driven wheel; 5, driven gear; 6, helical gear; 7, reduction gearing; 8, bearing; 9, lid; 10, wedge band; 71, reduction gearing axle; 91, default hole.
Embodiment:
Embodiment: see shown in Fig. 1 to 3, a kind of automatically-controlled door brushless direct-current reducing motor, comprise DC brushless motor 1, box body 3 is fixed with DC brushless motor 1 on one side, another side is equipped with automatically-controlled door and drives rotating shaft 2, be fixed with driven wheel 4 in the rotating shaft of DC brushless motor 1, wedge band 10 is stretched on driven wheel 4 and the driven gear 5, be fixed with helical gear 6 on the axle of driven gear 5, helical gear 6 is meshed with reduction gearing 7, the default hole 91 that reduction gearing axle 71 passes on the lid 9 is fixed together with automatically-controlled door driving rotating shaft 2, and lid 9 is by being bolted on the box body 3.
Described helical gear 6 is 20 teeth, and reduction gearing 7 is 50 teeth.
Be fixed with the inner ring of bearing 8 on the described reduction gearing axle 71, be fixed with the inner ring of bearing 8 on the axle of driven gear 5, the outer ring of bearing 8 is fixed on the lid 9.
Form fixedly ear 31 on the described box body 3.
Operation principle: the utility model adopts driven wheel 4 to drive reduction gearing 5 by wedge band 6 and rotates, and does not adopt gearbox drive, and structure is more simple, more power saving.
Described helical gear 6 is meshed with reduction gearing 7, reduction gearing 7 adopts nylon gear, and described helical gear 6 is 20 teeth, and reduction gearing 7 is 50 teeth, allow 7 engaging pieces of helical gear 6 and reduction gearing not have the gap, the infringement of torsion in the time of reducing the counter-rotating of DC brushless motor so as far as possible.Because very close of the interlock of gear is even also can use DC brushless motor 1 normally in the area of cold.Do not exist yet product cold district can't operate as normal phenomenon.
