Abstract
The utility model discloses a balanced-force electric motor transmission decelerating device used for the rolling shutter which comprises an electric motor, a decelerating mechanism and an output shaft. The decelerating mechanism comprises a worm wheel, a worm, a transmission disc as well as a planetary transmission gear arranged on the transmission disc. The output shaft is fixed on the transmission disc. The outside of the planetary transmission on the transmission disc and the gear inside the shell are meshed. The inside of the planetary transmission and the central gear of the worm wheel are meshed. The worm wheel is driven by the worm. The worm and the electric motor shaft are coupled. The utility model has the advantages of small volume, good self-locking performance, small noise and stable working performance.
Description
Technical field
The utility model relates to a kind of variable speed drive, particularly a kind of shutter door equilibrant electric-motor-driving speed reducer.
Background technique
Existing two kinds of shutter doors equilibrant electric-motor-driving speed reducer, first kind is to use worm gear and worm screw as reduction gearing mechanism, yet such reduction gearing mechanism has obvious defects: when the first, the motor outputting torsion is excessive, cause the worm screw fracture easily, or the worm gear wearing and tearing; The second, the self-lock force deficiency of worm gear, worm screw, especially more serious after the wearing and tearing, the volume lock is pushed open easily by force, Security is relatively poor; Three, the torsion of output shaft is less equally, and volume lock lifting force deficiency is often burnt motor easily.Second kind of shutter door comprises the internal tooth block set with the reducing gear of equilibrant electric-motor-driving speed reducer, some group switching centre drive plates are housed in the internal tooth block set, symmetric arrangement has the planetary reduction gear tooth on the drive plate of center, and the tooth engagement of each planetary reduction gear tooth outside and internal tooth block set, and motor shaft end is equipped with a center driving cog, the planetary reduction gear tooth inner mesh on center driving cog and one of them the center drive plate.Yet, the motor shaft of above-mentioned transmission decelerating device and output shaft are almost on same straight line, the almost parallel distribution of some group switching centre drive plates and each group planetary reduction gear tooth has caused the length of above-mentioned transmission decelerating device long, volume is excessive, is installed on the shutter door cumbersome like this; And its self-lock ability deficiency, the volume lock is pushed open equally easily by force; The noise of Chan Shenging is excessive in the course of the work, and the torsion of output shaft is less equally, and volume lock lifting force deficiency is burnt motor equally easily.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provide that a kind of volume is little, self-locking property good, noise is little and the shutter door of stable work in work with equilibrant electric-motor-driving speed reducer.
The technological scheme that its technical problem that solves the utility model adopts is: shutter door equilibrant electric-motor-driving speed reducer, comprise motor, reducing gear and output shaft, it is characterized in that: described reducing gear comprises worm gear, worm screw, drive plate and is installed in Gear Planet Transmission tooth on the drive plate, output shaft is fixed on the drive plate, mesh with the tooth in the shell in the Gear Planet Transmission tooth outside on the drive plate, the Gear Planet Transmission tooth is inboard to be meshed with the worm gear centre tooth, worm gear is driven by worm screw, and worm screw connects with motor shaft.
Wherein, the end of described worm screw is provided with groove vertically, cell body run through worm screw the surface, the motor shaft end is provided with the projection that matches with groove, projection is absorbed in the draw-in groove and realizes that worm screw connects with motor shaft.
Wherein, described drive plate is one, and the Gear Planet Transmission tooth that is installed on the drive plate is one group three, and three Gear Planet Transmission teeth are symmetrically distributed.
Wherein, described motor adopts the 7000-25000r/min DC micromotor, and the rotating speed of output shaft is 30-100r/min.
The beneficial effects of the utility model are: because motor is passed to output shaft by worm screw, worm gear, Gear Planet Transmission tooth and drive plate with power, thereby effectively reduce the noise that the Gear Planet Transmission tooth produces because of high speed rotating; And output shaft and motor shaft be almost vertical distribution, so just can effectively reduce length of the present utility model, dwindles its volume, is convenient to the utility model with this and is installed on the shutter door.In addition, the rotating speed of output shaft of the present utility model is 30-100r/min, thereby guarantees to the utlity model has bigger torsion and self-locking property, guarantees that it reliablely and stablely works.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the decomposition texture schematic representation of the utility model preferred embodiment;
Fig. 2 is the plan view of the utility model preferred embodiment;
Fig. 3 is that the A of drive plate shown in Fig. 1 and Gear Planet Transmission tooth is to view.
Embodiment
Referring to figs. 1 through Fig. 3, shutter door equilibrant electric-motor-driving speed reducer, comprise motor 1, reducing gear and output shaft 2, described reducing gear comprises worm gear 3, worm screw 4, drive plate 5 and is installed in Gear Planet Transmission tooth 6 on the drive plate 5, output shaft 2 is fixed on the drive plate 5, tooth 8 engagements in Gear Planet Transmission tooth 6 outsides on the drive plate 5 and the shell 7,6 inboard and worm gear 3 centre tooth 9 engagements of Gear Planet Transmission tooth, worm gear 3 is driven by worm screw 4, and worm screw 4 connects with motor shaft 10.Motor is passed to output shaft by worm screw, worm gear, Gear Planet Transmission tooth and drive plate with power, thereby effectively reduces the noise that the Gear Planet Transmission tooth produces because of high speed rotating; And output shaft and motor shaft be almost vertical distribution, so just can effectively reduce length of the present utility model, dwindles its volume, is convenient to the utility model with this and is installed on the shutter door.In addition, the rotating speed of output shaft of the present utility model is 30-100r/min, thereby guarantees to the utlity model has bigger torsion and self-locking property, guarantees that it reliablely and stablely works.
Wherein, the end of described worm screw 4 is provided with groove 11 vertically, cell body run through worm screw 4 the surface, motor shaft 10 ends are provided with the projection 12 that matches with groove, projection 12 is absorbed in the draw-in groove 11 and realizes that worm screw 4 connects with motor shaft 10.This connecting mode can guarantee that the central axis of motor shaft 10 and worm screw 4 can reliablely and stablely not work yet on same axis.
