Description
Technical field
The utility model relates to a kind of rapid door motor, belongs to field of motor manufacturing.
Background technology
Common rapid door generally utilizes motor driving work in the market, makes the door curtain cloth scrolling of rapid door by the power transmission shaft of motor with movable reel rotation, reaches the object of switching door.Traditional rapid door often directly adopts high-speed electric expreess locomotive to drive door curtain, often controls comparatively fuzzyly, causes the lifting noise of door curtain large, collides comparatively strongly, and application life is not long.
Patent No. CN 203499540 discloses a kind of rapid door electric motor mounting structure, by parallel with reel the motor installation of rapid door, then drives reel work by chain gear transmission, has expanded to greatest extent the area of rapid door, has improved the protection effect in safety.But this structure is still and uses motor direct-drive door curtain, impacts larger to door curtain.And conventional planetary gear structure deceleration device volume is large, the holding capacity of high pulling torque ground starting is lower.And the rapid door that adopts pure motor switch needs large measuring mechanism to ensure supply of electric power.
Utility model content
The utility model, for solving prior art problem, provides the rapid door that a kind of noise is little, volume is little motor.
The technical solution of the utility model is: a kind of rapid door motor, comprise casing, be arranged at the motor in described casing, the reducer that is connected in the rotating shaft of described motor and is connected with output shaft, and be connected in the hand gear of the rotating shaft of described motor simultaneously.
As preferably, described reducer comprises and the rotating shaft of described motor be directly fixed with some quantity be even number and adjacent between the eccentric bushing of mutual dislocation, on described eccentric bushing, be provided with roller bearing; Described reducer also comprises the escapement that two axis are parallel to each other, and the connecting line mid point at two escapement centers is positioned on the central axis of described roller bearing; Described reducer also comprises that an inner surface arranges the output casing that is arranged with pin tooth along even circumferential, and described pin tooth is meshed with described escapement, and described output casing is fixedly connected with the output shaft of described reducer.
As preferably, the quantity of described eccentric bushing is any one in two, four, six or eight.
As preferably, described hand gear comprises an extension rod being fixedly connected with described motor rotary shaft, can with the intermeshing transiting rod of described extension rod, and the hand lever of the handle that can be connected.
As preferably, described transiting rod is meshed with described extension rod by expansion link.
As preferably, described expansion link comprises some along the equally distributed elastic foldable bar of described transiting rod cross-sectional periphery, and the elasticity direction of described elastic foldable bar is for making described transiting rod away from described extension rod.
As preferably, described transiting rod is mutually vertical with described hand lever, and the contact site of described transiting rod and described hand lever is provided with respectively intermeshing and axial orthogonal angular wheel.
The utility model adds hand gear, in the time that supply of electric power cannot ensure, adopts manual mode to open door curtain.And motor of the present utility model has added reducer, and the reducer of the utility model structure is in the time that the rotating shaft of motor is rotated with eccentric bushing, due to the feature of tooth curve on escapement and be subject to the restriction of pin wheel housing upper pin gear pin therefore, the motion of escapement becomes the plane motion that has revolution to have again rotation, in the time that the rotating shaft of motor is just being circled, eccentric bushing also rotates one week, thereby escapement turns over poor a deceleration of tooth in rightabout, relend and help output mechanism, the low speed autorotation of escapement is passed through to bearing pin, pass to output shaft, thereby obtain lower output speed.Rapid door, in switching process, need to accelerate to flank speed by door curtain with great moment of torsion when startup, in the time that door curtain will arrive stroke, needs again to be oppositely decelerated to and approaches staticly, therefore needs door curtain and motor rotary shaft needs are shock-resistant, inertia is little.And that this reductor has speed reducing ratio is large, transmission efficiency is high, and volume is little, lightweight, fault is few, and the life-span is long, smooth running is reliable, and noise is little, easy accessibility, easily maintenance, simple in structure, the overload capacity that most importantly this reductor has is strong, shock-resistant, the features such as moment of inertia is little, are extremely applicable to rapid door and use.
Hand gear is connected with motor rotary shaft by telescopic transiting rod, and in the time of electric motor normal working, by the tension force of expansion link, hand gear is thrown off; In the time that motor cannot be worked, by compressing expansion link, make transiting rod and extension rod engagement, hand gear can be controlled output shaft rotation.
In sum, the utlity model has following advantage:
1, this electromotor overload ability is strong, shock-resistant, and moment of inertia is little;
2, simple in structure, low cost of manufacture.
