Abstract

An electric powered rolling door transmission device comprises a motor, a reduction mechanism, an output mechanism and a work mechanism, which is characterized in that the reduction mechanism is a first-level reduction small-gear-teeth difference reducer consisting of an concentric shaft integrated with the motor shaft as a whole, a planetary gear bearing arranged on the concentric shaft, a planetary gear and an inner gear ring that is fixed on the end cover of the motor; two or more ball link levers used for transferring the power are arranged between the planetary gear and an output ring fixed on the output shaft, which simplifies the structure transferring the power from the concentric shaft to the central output shaft. In addition, an electromagnetic iron and the power source-a battery of the electromagnetic iron is enclosed on the output shaft, which can utilize the electromagnetic force to separate the clutch so as to enable the manpower to open and close the rolling door. The device has simple structure, reliable work and low cost.

Description

A kind of electric rolling door transmission device

Technical field.The utility model relates to the electronic and dual-use manual transmission device of a kind of rolling door transmission device, particularly rolling door.

Background technology.Existing rolling door transmission mechanism generally adopts multi-stage speed-reducing mechanism, and the output mechanism after the deceleration is also complicated, so just makes whole transmission device seem numerous and jumbled, and body weighs greatly, and manufacturing and matching requirements are higher, and cost increases.

Summary of the invention.The purpose of this utility model provides that a kind of structure is fairly simple, reliable operation, cost are lower, can manually operated electric rolling door transmission device when having a power failure.

The utility model is so to realize: a kind of electric rolling door transmission device comprises motor, reducing gear, output mechanism, operating mechanism and each fastening keeper, output mechanism is by output shaft and bearing thereof, be installed in output ring and bearing thereof on the output shaft, clutch, goring push spring and form with the minor sprocket that is set on the output shaft copper sheathing that quiet of clutch is fixedly connected, operating mechanism comprises hinge wheel, curtain rolling shaft, be installed on the curtain rolling shaft and the roller shutter dish of fixedlying connected with rolling door upper end curtain plate, by the control stroke gear that is loaded on the output shaft copper sheathing and is fixedly connected with quiet of clutch, screw rod with control stroke gear meshed transmission gear, the travel control device that migration is formed in order to the nut of control run switch on screw rod, it is characterized in that reducing gear is by affixed with the motor shaft extension or make the eccentric shaft of one, the planetary gear supporting, planetary gear, be installed in the little tooth difference speed reducer of the one-level deceleration of the ring gear composition on the electric motor end cap, it is circumferentially uniform in order to the ball head connecting rod of transferring power and the spherical shell and the spherical shell detent mechanism of the other end thereof that two or more are housed between planetary gear and output ring, when having a power failure, utilize electromagnetic attraction to overcome spring thrust being with one on the output shaft of clutch motion block one side, make clutch separation so that manpower opens and closes electromagnet and power supply thereof---the battery of rolling door.

Above-mentioned reducing gear and output mechanism are combined into " a kind of little tooth difference speed reducer ", and I propose Chinese patent application on the same day with the utility model application.According to the supporting capacity that rolling door opens and closes, the utility model adopts this reducer, can make this simplified, and manufacturing and installation are all easier, and practicality is reliable, cost is lower.

Description of drawings.Accompanying drawing is a cross-sectional schematic of the present utility model.

Illustrate: 1, minor sprocket 2, copper sheathing 3, quiet 4 on clutch, clutch motion block 5, goring push spring 6, electromagnet 7, back-up ring 8, output shaft 9, key 10, spherical shell 11, output ring 12, ring gear 13, ball head connecting rod 14, planetary gear 15, planetary gear supporting 16, eccentric shaft 17, motor shaft extension 18, jump ring 19, motor bearings 20, electric motor end cap 21, rubber pad 22, jump ring 23, bearing 24, clutch tooth portion 25, spline 26, clutch outer member 27, control stroke gear 28, spacer 29, clutch outer member cover plate 30, bearing 31 bearing covers.

Embodiment.A kind of electric rolling door transmission device comprises motor, reducing gear, output mechanism, operating mechanism and screw, fastening keeper such as jump ring, output mechanism is by output shaft 8 and bearing 30 thereof, the output ring 11 and the bearing 23 thereof that are set on the output shaft 8 and connect with key 9 with it, jaw clutch, goring push spring 5 and form with the minor sprocket 1 that is set on output shaft 8 copper sheathings 2 that quiet 3 on clutch is fixedly connected, operating mechanism comprises hinge wheel, curtain rolling shaft, be installed on the curtain rolling shaft and the roller shutter dish of fixedlying connected with the rolling door curtain plate, by the control stroke gear 27 that is loaded on output shaft 8 copper sheathings 2 and is fixedly connected with quiet 3 on clutch, screw rod with control stroke gear 27 meshed transmission gear, the travel control device that migration is formed in order to the nut of control run switch on screw rod, it is characterized in that reducing gear is by making the eccentric shaft 16 of one with motor shaft extension 17, planetary gear supporting 15, planetary gear 14, be installed in the little tooth difference speed reducer that one-level that the ring gear 12 on the electric motor end cap 20 forms is slowed down, planetary gear 14 and output encircle be equipped with between 11 two circumferential uniform in order to the ball head connecting rod 13 of transferring power and the spherical shell 10 and the jump ring 22 of the other end thereof.Between planetary gear 14 and output ring 11, also be provided with the rubber pad 21 that can reduce to vibrate, reduce noise, utilize electromagnetic attraction to overcome spring 5 thrusts when on the output shaft of clutch motion block 4 one sides, being with a power failure and make jaw clutch motion block 4 slide disengaging quiet 3 (as shown in drawings) so that manpower opens and closes electromagnet 6 and power supply thereof---the battery of rolling door along spline 25.

During work, remote-controlled receiver receives that remote controller signal is promptly by the electric appliance control box starting motor, be loaded on the planetary gear 14 in 16 supportings 15 of motor shaft extension eccentric shaft, in the rotation that when ring gear 12 revolves round the sun fast, has obtained low speed, and by ball head connecting rod 13, through output ring 11, make output shaft 8 obtain the needed slow-speed of revolution, at this moment jaw clutch carries out the switching work of rolling door in pushing tow lower tooth portion 24 engagements of spring 5 so minor sprocket 1 drives hinge wheel driving curtain rolling shaft by chain.If just transfer to open, then be reversed to and close.By the screw rod that is loaded on the control stroke gear 27 gears engaged rotation on the output shaft 8 and the nut control run switch of migration on screw rod, when initial point is gone up in rolling door unlatching arrival, touch travel switch, make it to open circuit the motor stall.Otherwise, close when arriving lower dead center when rolling door, touch another travel switch and make it to open circuit, the motor stall reaches the purpose of automatic spacing.

During power failure, remote-controlled receiver is received remote controller signal promptly by electric appliance control box, and electromagnet 6 coils and battery are connected, and overcomes the jacking force of spring 5 with magnetic attraction, makes clutch break away from engagement, so just can manual mode switching rolling door.
