Description
Technical field
The utility model relates to a kind of electric open-door mechanism.
Background technology
At present domestic also fewer to revolving electric door; Has plenty of the pure driven by motor of leaning on; Such method is bigger to the hazard ratio of motor, and can not realize well that door can both produce self-locking in any position, the technological deficiency of existence: motor short, no auto-lock function in application life.
Summary of the invention
The deficiency of, no auto-lock function short for the motor application life that overcomes existing electric open-door mechanism, the utility model provide a kind of electric rotary door-opening mechanism that prolongs motor application life, has the lock-bit function.
The utility model solves the technical scheme that its technical problem adopted:
A kind of electric rotary door-opening mechanism comprises that skin is shaken on a left side and skin is shaken on the right side, and a said left side is shaken skin and is fixedly mounted on the jackshaft; The said right side is shaken micromicro and is installed on the jackshaft rotationally; The said right side is shaken skin and is fixedly mounted on the body of wall, and a said left side is shaken skin and is fixedly mounted on the door, and said door-opening mechanism also comprises planet wheel decelerator and drive motors; The output shaft of said drive motors is connected with the power shaft of said planet wheel decelerator, and the output shaft of said planet wheel decelerator connects with said jackshaft.
Further; Said planet wheel decelerator comprises reduction box, sun gear, planetary gear, planetary carrier, outer ring Positioning Gear and outer ring travelling gear; The main shaft of said sun gear connects with the output shaft of drive motors; Said sun gear and planetary gear engagement, said planetary gear is installed on the planetary carrier, and said planetary gear meshes with outer ring Positioning Gear and external toothing travelling gear simultaneously; Said outer ring Positioning Gear is fixedly mounted in the said reduction box, and said outer ring gear is fixedly connected with the output shaft of planet wheel decelerator.
The technical conceive of the utility model is: in order to realize protecting motor; Prevent that driving door by external force rotates the counter-rotating of drive motor shaft and burn out motor; And the angle difference that can adapt to the folding of different local required doors; Designed a kind of planetary gear reducing gear, the sun gear that the rotation of motor drives in the planetary gear reduction box rotates, thereby the output shaft that drives planetary gear rotates; The planetary gear output shaft drives through key connecting and shakes the skin rotation; Thereby realize opening and closing of door, the angle of opening the door and speed are confirmed velocity of rotation and the rotational angle and the gearratio of motor according to demand in advance through programming, and come time that control gate is held open state to prevent to press from both sides the generation of an accident through sensor.In the lower end of door-hinge, adopt thrust ball bearing simultaneously, can well reduce the friction factor of door-hinge, improve transmission efficiency, go for the heavier safety door of quality.
The sun wheel shaft of motor shaft and planetary gear reduction box is an one; Make structure compact more like this; Driving coupling in the middle of reducing, with high transmission efficiency, what the planetary gear reduction box adopted is the pattern design of 3Z (II) type; The symmetric pattern of three planetary gears makes stress equalization, and planet wheel decelerator output shaft and the intermediate rotary shaft one of shaking skin are built through binding.The minimum suitable value of the gearratio of 3Z (II) type planetary gear is i=64, and promptly power can amplify 64 times, can be with the normal operation of the driven by motor door of smaller power.Motor is through rotating, can realize the folding of door, and also can recently realize the speed of switch door through the transmission that changes planetary gear, and the number of turns that motor changeed is drafted the angle after the unlatching.
Simultaneously, the auto-lock function of planetary gear reduction box also makes and can be fixed on certain angle and can freely not rotate through external force, has well realized gate inhibition's function, has higher security coefficient
The beneficial effect of the utility model mainly shows: prolong motor application life, have the lock-bit function.

Fig. 3 is that the A-A of Fig. 2 is to view.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1～Fig. 3; A kind of electric rotary door-opening mechanism comprises that skin is shaken on a left side and skin is shaken on the right side, and a said left side is shaken skin and is fixedly mounted on the jackshaft; The said right side is shaken micromicro and is installed on the jackshaft rotationally; The said right side is shaken skin and is fixedly mounted on the body of wall, and a said left side is shaken skin and is fixedly mounted on the door, and said door-opening mechanism also comprises planet wheel decelerator and drive motors; The output shaft of said drive motors is connected with the power shaft of said planet wheel decelerator, and the output shaft of said planet wheel decelerator connects with said jackshaft.
Said planet wheel decelerator comprises reduction box 5, sun gear 9, planetary gear 7, planetary carrier 14, outer ring Positioning Gear 10 and outer ring travelling gear 6; The main shaft of said sun gear 9 connects with the output shaft of drive motors; Said sun gear 9 and planetary gear 7 engagements; Said planetary gear 7 is installed on the planetary carrier 14; Said planetary gear 7 meshes with outer ring Positioning Gear 10 and external toothing travelling gear 6 simultaneously, and said outer ring Positioning Gear 10 is fixedly mounted in the said reduction box 5, and said outer ring travelling gear 6 is fixedly connected with the output shaft of planet wheel decelerator.
In the present embodiment, about shaking skin and dividing two, one through screw on body of wall; Other one is fixed on the door, and the jackshaft that shakes skin is the output shaft of planet wheel decelerator, through key; The left side shake skin and rotating shaft through key connecting, and with axle be interference fit, it is through matched in clearance with axle that skin is shaken on the right; It promptly is the motion mode of jackshaft that the rotation of door realizes, jackshaft and outer ring travelling gear 6 are one.The rotation that whole motion starting point is a drive motors 12 is sun gear 9 and rotates, and sun gear rotates and drives 7 rotations of three planetary gears, and planetary gear is supported by planet stent 14; Outer ring Positioning Gear 10 and the interior engagement of planetary gear, outer ring Positioning Gear 10 passes through screw on deceleration box, simultaneously; Planetary gear also meshes with outer ring travelling gear 6; Screw 2 is linked as integral body to deceleration box and motor, and deceleration box is through bolt shaking on the skin on the right, and then is fixed on the body of wall.
Consult accompanying drawing 5, adopt thrust ball bearing under the door-hinge, can reduce frictional force, improve the running efficiency of whole device, and then improve supporting capacity, reduced loss motor gear etc.
