Description
Technical Field
The utility model belongs to the technical field of the industry transmission, concretely relates to drive arrangement for be used for door curtain.
Background
At present, a quick rolling door is a barrier-free isolation door capable of being lifted quickly, and the quick rolling door is a door which is formed by connecting PVC door sheets in series and rotates up and down by taking a scroll above the door as a center in a fixed door frame. And the door curtain is rolled up and need be followed the cylinder and is rolled up, and the drive drum rotation needs the motor to accomplish the drive, and traditional motor drive cylinder is placed and is come the drive drum rotation in the cylinder outside, and the operational environment who is used for quick rolling slats door is not all good always, and when meetting the weather of strong wind and heavy rain, often can take place the motor and get into the rainwater and break down and can't drive the cylinder operation, perhaps the external moist environment can influence the life of motor.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model aims to solve the technical problem that a simple structure is provided, simple to operate, operation are reliable, maintain portably for drive arrangement on the door curtain especially places the mode that sets up of cylinder in the motor in, both can reduce the space of installation, protection motor that again can be better.
The utility model discloses frame construction's technical scheme as follows: a driving device for a door curtain comprises a roller for winding the door curtain, wherein a motor is arranged in the roller and is parallel to the roller; an external gear is arranged on a motor shaft of the motor, a through hole is formed in the end face of the front end of the roller, an internal tooth structure is arranged on the inner wall of the through hole, and the internal tooth structure is meshed with the external gear; the tail end of the motor is fixed on the flange plate, a bearing is embedded in the flange plate, and the bearing is matched with the curved wall at the rear end of the roller.
The optimized structure is that one side of the flange plate is provided with an end plate, the end plate and the flange plate are respectively provided with a plurality of matched threaded holes, and the threaded holes realize the fixed connection of the end plate and the flange plate in a bolt mode.
Preferably, the body of the motor does not contact with the inner wall of the drum.
Preferably, the through hole is located on the axis of the drum.
The beneficial effects of the utility model are that the utility model discloses a drive arrangement, overall structure reasonable in design, the operation is reliable and stable, places the drum-type design in the motor, both can reduce the space of installation, protection motor that again can be better.

Detailed Description
The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
1-2, a driving device for door curtain, comprising a roller 2 for winding the door curtain, wherein the door curtain is wound on the roller 2 during the ascending process, the rolling of the roller 2 needs the driving of a motor 1, the space inside the roller 2 is utilized for better reducing the installation space, and the motor 1 is arranged inside the roller 2, so that the space occupied area can be reduced by the built-in arrangement of the motor 1, the function of ascending and descending the door curtain is completed by the way that the roller 2 rotates around the axis, therefore, the motor 1 and the roller 2 need to be arranged in parallel, and the purpose is that the motor shaft of the motor 1 is also parallel to the roller 2.
Above-mentioned motor 1's motor shaft needs to drive the rotation of cylinder 2, and motor 1's motor shaft and cylinder 2's transmission mode are equipped with outer gear 3 on motor 1's motor shaft, and the terminal surface department of 2 front ends of cylinder is equipped with a through-hole, and the inner wall of through-hole is equipped with the internal tooth structure, the internal tooth structure with 3 intermeshing of outer gear, consequently under motor 1's drive, the motor shaft drives 3 rotations of outer gear, and outer gear 3 and internal tooth structure's through-hole intermeshing to realize cylinder 2's rotation, and the position of through-hole is located cylinder 2's axis, thereby satisfy cylinder 2's rotation around cylinder 2's axis rotation.
Under satisfying above-mentioned cylinder 2's drive, need consider motor 1's fixed and the rotatory stability of cylinder 2, motor 1's tail end is through fixing on ring flange 4, and the fixed mode adopts bolted connection mode to installation and dismantlement, the last bearing 6 that still embeds of ring flange 4, bearing 6 with the curved wall of cylinder 2 rear end is mutually supported, and bearing 6 can reduce the friction that cylinder 2 brought at rotatory in-process, improves sensitivity, guarantees rotatory stability.
One side of the flange plate 4 is provided with an end plate, the end plate and the flange plate 4 are respectively provided with a plurality of threaded holes matched with each other, and the threaded holes are used for realizing the fixed connection of the end plate and the flange plate 4 in a bolt mode.
The body of the motor 1 is not in contact with the inner wall of the roller 2, so as to better protect the service life of the motor 1.
The preferred embodiments and examples of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the embodiments and examples, and various changes can be made without departing from the concept of the present invention within the knowledge of those skilled in the art.
