Description
Technical field
The utility model relates to the field of variable speed drive, particularly the speed reducer of electric rolling gate door usefulness.
Background technique
In the shutter door balanced power device, generally comprise the motor and the speed reduction gearing of paired configuration, in order to promote or to put down the volume brake lining.Traditional reducing gear adopts worm gear, worm speed-down driving mechanism more, but application for many years shows that such reduction gearing mechanism has obvious defects: when 1, the motor outputting torsion is excessive, or cause the worm screw fracture easily, or the worm gear wearing and tearing; 2, the self-lock force deficiency of worm gear, worm screw, especially more serious after the wearing and tearing, shutter door is pushed open easily by force, Security is relatively poor; 3, the torsion of output shaft is less, and volume lock lifting force deficiency often causes burning motor easily.
The model utility content
The purpose of this utility model is the deficiency that overcomes conventional art, proposes that a kind of volume is small and exquisite, self-locking property good, the shutter door of stable work in work balance motor transmission decelerating device.
The technical solution of the utility model is: shutter door balance motor transmission decelerating device, include direct current generator, be subjected to motor-driven reducing gear, output shaft and shell, constituting of reducing gear: the front end edge motor shaft of motor is to being fixed with an internal tooth block set, at least one group switching centre drive plate is housed in the internal tooth block set, symmetric arrangement has the planetary reduction gear tooth on this center drive plate, 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, and mesh with this center driving cog again simultaneously each planetary reduction gear tooth inboard.Further, the center drive plate that is loaded in the internal tooth block set has three groups, their annexations side by side are: the first center driving cog engagement of first group of planetary reduction gear tooth on the first center drive plate and motor shaft end, on the protruding axle of drive plate back, first center second center driving cog is housed, the second center driving cog engagement on second group of protruding axle of planetary reduction gear tooth and the place ahead on the second center drive plate, on the protruding axle in the back of the second center drive plate the 3rd center driving cog is housed, the 3rd group of planetary reduction gear tooth on the 3rd center drive plate and the place ahead the 3rd center driving cog engagement, the back of the 3rd center drive plate is an output shaft.And the planetary reduction gear tooth on each center drive plate is three gears, and they are symmetrically distributed on the same disk, and all rotate with the internal tooth engagement of internal tooth block set in the outside.It is the DC micromotor of 8000-30000r/min that motor adopts rotating speed.
This structure, by center drive plate, center driving cog, planetary reduction gear tooth with the output of high-speed electric expreess locomotive be converted into big torsion, the slow-speed of revolution is exported from output shaft, advantage such as have the mounting structure compactness, volume is small and exquisite, self-locking property good, outputting torsion is big.And this structure can reduce production costs greatly with one group of traditional two groups of device arranged in pairs of device replacement.

Embodiment
Referring to Fig. 1-Fig. 4, the transmission decelerating device of present embodiment is mainly used on the shutter door, and main body includes shell 1, is packaged in direct current generator 2 and reducing gear in the shell 1, base 3, output shaft 4.Special design is reducing gear, and its internal tooth block set 5 barrel-shaped by a fixed hollow, that have internal tooth is loaded on three group switching centre drive plates in the internal tooth block set 5, three groups of totally nine planetray reducers, and three center driving cogs are formed by connecting side by side.The axle head of motor 2 is equipped with the first center driving cog 6, first group of planetary reduction gear tooth 8 (three gears of symmetrical distribution) on it and the first center drive plate 7 meshes simultaneously, meanwhile, the outside of first group of planetary reduction gear tooth 8 also with the engagement of the internal tooth of internal tooth block set 5, because internal tooth block set 5 maintains static, when motor 2 rotates, the first center driving cog 6 will drive first group of planetary reduction gear tooth 8 and rotate along the deceleration of internal tooth block set 5 inwalls, and drive 7 rotations of the first center drive plate; On the protruding axle in the back of the first center drive plate 7 the second center driving cog 6 ' is housed, three gears of second group of planetary reduction gear tooth 8 ' on it and the adjacent second center drive plate 7 ' mesh simultaneously, equally, second group of planetary reduction gear 8 ' all with the tooth engagement of internal tooth block set 5, when the second center driving cog 6 ' rotates, the gearing down mode of the second center drive plate 7 ' and above-mentioned first group roughly the same, on the protruding axle in the back of the second center drive plate 7 ', the 3rd center driving cog 6 is housed "; it and the 3rd center drive plate 7 " on the 3rd group of planetary reduction gear tooth 8 " engagement simultaneously; the 3rd group of planetary reduction gear tooth 8 " also with the tooth engagement of internal tooth block set 5, the gearing down mode is also same with second category.Like this, 4 form the third-level planetary gear reduction from motor 2 to output shaft, and the reduction speed ratio of each grade gear train is about 5～10: 1.And direct current generator 2 adopts the high-speed electric expreess locomotive of 8000-30000r/min, and the back of slowing down can obtain the slow-revving output of big torsion of 30-100r/min at output shaft 4.Owing to adopt three grades of decelerations side by side, whole self-locking property is fabulous, and shutter door can't be reversed and push open.And every group of equal symmetric arrangement of planetary reduction gear tooth, stable work in work, the space compactness makes volume small and exquisite, is convenient to mounting arrangements.
Certainly, only enumerated a kind of preferred implementation here, the quantity of the quantity of center drive plate, planetary reduction gear tooth etc. all can change according to the design needs, and the protection domain that other is equal to, structure roughly the same all should belong to this patent repeats no more here.
