Description
Technical field
It the utility model is related to rolling screen door, more particularly to a kind of rolling screen door drive device.
Background technology
In the conventional technology, most rolling screen door are all the type of drive using alternating current generator, i.e., motor is using exchange rolling door
Motor, the rolling screen door of this structure are that have alternating current generator to carry out speed change and increasing by the gear in gearbox and other driven gears
Strong moment of torsion, spool and rolling door action are driven, this type of drive is disadvantageous in that the pulling force of alternating current generator is inadequate, and all
The component such as electric capacity it is more, it is difficult to meet the requirement of the high-torque needed for rolling screen door product.The electricity of also another rolling screen door
Machine is to use DC brush permanent magnetism rolling door motor, but it is also required to a set of speed change gear and drives spool and rolling door, overall structure school
Position is complicated.
In order to overcome above mentioned problem, one kind has been proposed in the prior art can use brshless DC motor as power
The drive device that source is driven, this mode overcome the deficiency of conventional art, have moment of torsion is big, motor output power is big,
The advantages that rotating speed is slow and uses electric current small, the dresses such as gear in transmission transmission mechanism can be removed using brshless DC motor
Put, production cost can be reduced；But there is also an issue, i.e., the height that rolling screen door is opened can not be controlled accurately, rolling screen door
The speed of service can only be adjusted within the specific limits by gear, main cause is because the transmission of motor and spool is to utilize
The drive of chain, and the security of chain drive is relatively low, if chain fractures due to wear or overloading, rolling screen door can be because
Accident is caused for deadweight whereabouts, therefore this mode need to be improved.
The content of the invention
In order to overcome above mentioned problem, this is new to provide a kind of rolling screen door that can accurately control rolling screen door operation precision and uses
Drive device.
To achieve the above object, the technical scheme of this new offer is：
A kind of rolling screen door drive device, including spool, motor and installing plate composition；The output of described spool and motor
Axle is each attached on installing plate, and linkage is provided between the spool and motor output shaft；Described linkage bag
Include one-stage gear, idler gear and secondary gear；Described one-stage gear is fixed on the output shaft of motor, and one-stage gear is set
Between motor and installing plate；One end of described spool passes through installing plate, and spool passes through and is provided with two on one end of installing plate
Level gear, idler gear is arranged between one-stage gear and secondary gear, idler gear simultaneously with one-stage gear and secondary gear
Engagement.
The axis of described one-stage gear and the axis of idler gear are located in same level, the axis of one-stage gear with
The axis of secondary gear is not in same level.
The one-stage gear, idler gear, secondary gear three's structure are identical, and described one-stage gear includes tooth, tooth
Tooth and mounting hole, teeth are evenly distributed on the circumference of tooth, mounting hole site in the center of circle of tooth, the mounting hole of one-stage gear with
Motor output shaft is fixedly connected；Tooth gap, guide and compression piece are provided with the tooth；Described tooth gap is uniformly opened in tooth
On the circumference of part, it is spaced apart with teeth；Described guide is located at the both sides of tooth circumference, and compression piece is enclosed in tooth, embedding
Between guide；Guide groove is provided with the compression piece, guide groove is recessed in tooth gap, is corresponded with tooth gap.
Above-mentioned technical proposal is beneficial in that：
Originally it is new to provide a kind of rolling screen door drive device, because motor is directly to drive two level by idler gear
Pinion rotation, the rotation of spool is driven with this, the mode of this gear engagement can realize that motor stops, and spool stops, motor
The then dynamic purpose of spool, compared with prior art, this is new can accurately control roller shutter rise or fall position；And due to three
Intermeshing between individual travelling gear, pitch wheel can form auto-lock function, can prevent in the prior art because
Chain fractures and causes the situation of the uncontrolled whereabouts of rolling screen door to occur.
It is clearly and completely described below in conjunction with the accompanying drawing technical scheme new to this, it is clear that described implementation
Example is this new part of the embodiment, rather than whole embodiments.Embodiment based on this in new, ordinary skill
The every other embodiment that personnel are obtained under the premise of creative work is not made, belong to this novel protected scope.
Brief description of the drawings
Fig. 1 is the structural representation of this new embodiment 1；
Fig. 2 is the front view of the one-stage gear of this new embodiment 1.
Embodiment
Embodiment 1
A kind of rolling screen door drive device, including spool 1, motor 2 and installing plate 3 form；Described spool 1 and motor 2
Output shaft be each attached on installing plate 3, be provided with linkage 4 between the spool 1 and the output shaft of motor 2；Described
Linkage 4 includes one-stage gear 41, idler gear 40 and secondary gear 42；Described one-stage gear 41 is fixed on motor 2
On output shaft, one-stage gear 41 is arranged between motor 2 and installing plate 3；One end of described spool 1 passes through installing plate 3, spool
1 through being provided with secondary gear 42 on one end of installing plate 3, idler gear 40 be arranged on one-stage gear 41 and secondary gear 42 it
Between, idler gear 40 engages with one-stage gear 41 and secondary gear 42 simultaneously；By such setting, because motor is directly logical
Cross idler gear and drive secondary gear to rotate, the rotation of spool is driven with this, the mode of this gear engagement can be realized
Motor stops, and spool stops, the motor purpose that then spool moves, compared with prior art, this new rising that can accurately control roller shutter
Or down position；And due to intermeshing between three travelling gears, pitch wheel can form auto-lock function,
It can prevent from causing the situation of the uncontrolled whereabouts of rolling screen door to occur because chain fractures in the prior art.
Preferably, the axis of the axis of described one-stage gear 41 and idler gear 40 is located in same level, one-level
The axis of gear 41 is with the axis of secondary gear 42 not in same level；By such setting, one-level tooth can be improved
Driving torque between wheel, idler gear, secondary gear three, reduces the resistance of motor, while also allows for changing idler gear
To reach the purpose of adjustment transmission speed ratio.
Described motor 2 includes brshless DC motor.
Specifically, the one-level tooth that the one-stage gear 41, idler gear 40, the three's structure of secondary gear 42 are identical, described
Wheel 41 includes tooth 410, teeth 411 and mounting hole 412, and teeth 411 are evenly distributed on the circumference of tooth 410, mounting hole 412
Positioned at the center of circle of tooth 410, the mounting hole 412 of one-stage gear is fixedly connected with the output shaft of motor 2；Set in the tooth 410
There are tooth gap 413, guide 414 and compression piece 415；Described tooth gap 413 is uniformly opened on the circumference of tooth 410, with teeth
411 are spaced apart；Described guide 414 is located at the both sides of the circumference of tooth 410, and compression piece 415 is enclosed in tooth 410, is embedded in
Between guide 414；Guide groove 416 is provided with the compression piece 415, guide groove 416 is recessed in tooth gap 413, with tooth gap
413 correspond；By such setting, at work, compression piece by guide nests on the circumference of tooth, compression piece
On guide groove be recessed in tooth gap, corresponded with tooth gap, during rotation, gear first contacts with compression piece, in drawing for guide groove
Lead it is lower carry out elastic extruding, be gradually inserted in tooth gap, and then realize at a fully engaged with tooth, the tooth of three gears can be improved
Contact compactness between tooth, slitless connection is realized, improve transmission stability, prevent teeth from skidding occur because of abrasion.
More specifically, described compression piece 415 includes elastic ring.
