Abstract
An electrical curtain transmission device comprises a box body, two transmission gears in which respectively engage into corresponding racks. The device is characterized in that the two transmission gears engage into each other; one of the transmission gears engages into a spur gear; output shaft of a worm wheel or umbrella gear or helical gear mounted on the motor shaft is coaxial to the spur gear. The electrical curtain transmission device has simple structure, smooth and steady transmission as well as regulated appearance.
Description
Technical field
The utility model relates to a kind of electrically driven curtain transmission device of two-way folding.
Background technique
Existing two-way folding electrically driven curtain, its two-way mobile tooth bar is driven by two driving gears, one of them driving gear and power input gear engagement, and another driving gear is by idle wheel and power input gear engagement, utilize idle wheel to realize bidirectional-movement, this complex structure.Owing to the input gear that is used as power with spur gear is connected with motor, make putting perpendicular to the curtain slideway of motor in addition, not attractive in appearance, the soundness of installation is poor.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and rational electrically driven curtain transmission device is installed.
The technical solution of the utility model is: a kind of electrically driven curtain transmission device, has box body, two driving gears that are contained in the box body are connected with a joggle with corresponding tooth bar respectively, it is characterized in that: two driving gears are meshed, the engagement of one of them driving gear and spur gear, it is coaxial with spur gear to be contained in the one kind of output shaft of worm and gear on the motor shaft or umbrella gear or spiral gear.
Because two driving gears directly are connected with a joggle, one of them driving gear is connected with motor shaft by spur gear and worm and gear thereof or umbrella gear or spiral gear, two purposes that the tooth bar movement direction is opposite have just been realized, omitted idle wheel, make designs simplification reasonable, saved the space, and stable drive is smooth and easy, three kinds of forms of worm and gear or umbrella gear or spiral gear, all can change the direction of power input shaft, therefore motor just can with curtain slideway laid parallel, not only outward appearance put regular, better than vertical disposing way installation soundness.
