Description
Technical field
The present invention relates to a kind of gear-box of convertible clockwise and anticlockwise.
Background technique
Existing fire resistance rolling shutter door mostly is the rectilinear rolling shutter door of a driven by motor, because it needs larger installing space, need to cause its restricted application by pre-buried conductor on body of wall.And some door opening spans greatly, continuously without column or non-directional occasion, the difficulty that rectilinear rolling shutter door is installed is very large, therefore has minority occasion that side formula rolling shutter door has been installed.Existing side formula rolling shutter door, drives because it needs two motors, has the nonsynchronous problem of motor, thereby causes slave motor to initiatively clicking and cause load, has not only taken electricity but also has reduced the utilization ratio of motor.
Summary of the invention
The object of the present invention is to provide a kind of gear-box of convertible clockwise and anticlockwise, can overcome above-mentioned defect, by the gear-box of convertible clockwise and anticlockwise is set, both saved the cost of a motor, avoided again interfering with each other between gear, convenient installation, has extended again working life of motor.
The present invention is achieved through the following technical solutions:
A kind of gear-box of convertible clockwise and anticlockwise, comprise active splined shaft and be movably connected in the sliding gear on active splined shaft, also comprise transmission shaft A, transmission shaft B, on described transmission shaft A, be provided with the driving gear A that can be meshed with sliding gear, on described transmission shaft B, be provided with the driving gear B that can be meshed with sliding gear, when described active splined shaft forward, described sliding gear is meshed with driving gear A, when described active splined shaft reversion, described sliding gear is meshed with drive wheel B.
Described active splined shaft is connected with motor output shaft, in the time of motor forward rotation, sliding gear slides into the initiatively lower end of splined shaft and is meshed with driving gear A, thereby drive transmission shaft A to rotate, transmission shaft A drives the spool of coupled rolling shutter door to rotate, thereby rolling shutter door is closed, and now, described transmission shaft B does driven rotation under the drive of rolling door axle; In the time that motor rotates backward, sliding gear upwards slides with driving gear A and separates along active splined shaft under centrifugal action, while arriving driving gear B position, be meshed with driving gear B, band nutating gear B rotates, and then driving transmission shaft B to rotate by driving gear B, transmission shaft B drives the spool of coupled rolling shutter door to rotate, thereby rolling shutter door can be opened, now, transmission shaft A does driven rotation under spool drives.So just can adopt a motor to realize two actions of opening the door, closing the door, save a motor, make total more reasonable, improve the working life of rolling shutter door.
Further, for realizing better the present invention, on described active splined shaft, be provided with taper key, on described sliding gear, be provided with the keyway matching with this taper key.Because taper key is mainly by overall viewing range and axial force, main by along the tangential mutual power transmission that compresses of axle, can be used in heavy duty and connect.
Further, for realizing better the present invention, described sliding gear and active splined shaft Spielpassung.Cause part easily to damage impact using, therefore adopt the mode of Spielpassung, can facilitate better sliding gear to slide because frictional force is excessive in order to prevent from using for a long time, avoiding rubbing excessively causes motion to be obstructed.
Further, for realizing better the present invention, on described transmission shaft A and transmission shaft B, be provided with gear, described transmission shaft A is all connected with door curtain spool by the chain engaging with gear with transmission shaft B.By adopting gear to be connected the mode of rolling door axle with chain, can effectively drive spool to rotate, thereby drive door curtain motion, realize the action of opening the door, close the door.
Further, for realizing better the present invention, on described transmission shaft A and transmission shaft B, be provided with belt pulley, described transmission shaft A is all connected with door curtain spool by the belt being arranged on belt pulley with transmission shaft B.By adopting belt pulley to drive door curtain spool to rotate, can effectively drive door curtain motion, realize door curtain switching motion.
Further, for realizing better the present invention, also comprise casing, described transmission shaft A and transmission shaft B two ends are automatically connected in casing by bearing rotary respectively.By casing is set, can prevent transmission shaft A, transmission shaft B and driving gear A, the driving gear B situation such as get rusty of making moist, and then the working life of improving equipment, by the mode that adopts bearing rotary to be dynamically connected, can reduce rotatingshaft A, the suffered frictional force of transmission shaft B as far as possible, reduce energy loss, and then improve the utilization efficiency of motor.
The present invention compared with prior art, there is following beneficial effect: the present invention is by arranging the gear-box of convertible clockwise and anticlockwise, when clockwise and anticlockwise, drive respectively two transmission shafts to rotate, realize respectively the action of opening the door and closing the door by a motor, can save motor, improve the utilization ratio of motor, two gear mutual noninterferences simultaneously, thereby the working life that can improve motor.
