Dynamic connection, is installed with one-level little gear and two level gear wheel, the one-level little gear and one-level gear wheel are meshed thereon；It is described
Secondary gear wheel shaft both ends connect with housing into rotation, are installed with two level little gear and cone gear, the two level little gear thereon
It is meshed with two level gear wheel；The output shaft connects with housing into rotation, and its one end stretches out hull outside, and the other end is located at housing
Inside, the end end are installed with cone pinion, and the cone pinion and cone gear are meshed.
Further, the input shaft, one-stage gear axle, secondary gear wheel shaft and output shaft are connected by bearing and housing into rotation
Connect.
Further, the gearbox side be provided be used for control rolling screen door open the door and at closing time position set in advance from
The dynamic limiter stopped, the limiter connect with gearbox transmission, and controller electrical connection.
The beneficial effects of the utility model are：Gearbox by one-level gear wheel and one-level little gear, two level gear wheel and
The engaged transmission of two level little gear, cone gear and cone pinion, the rotating speed of output shaft can be reduced；Pass through cone gear
With the engaged transmission of cone pinion, thus it is possible to vary transmission direction, be easy to output shaft during use by power transmission shaft and be located at reel
On conical gear group drive connection, drive spool turns, traditional chain transmission mode can be changed, overcome chain drive easy
The problem of falling chain or chain rupture, eliminates safe hidden trouble.
Brief description of the drawings
