(1) technical field:
The utility model relates to transmission mechanism, is specially a kind of device that improves the transmission of three wings automatic door.
(2) background technology:
In current existing three wings automatic door, its kind of drive is mainly belt and chain drive.
Chinese patent application manual (the patent No.: 200720090258) point out belt and chain drive, can effectively transmit between centers motion separated by a distance.But because their elongation and belt easily skids, relaxes, wear phenomenon, chain and belt are placed in three, four wing doors and are not suitable for, also dangerous.
Chain transmission requires center to center distance longer, illustrates that chain and sprocket can not seal, and long term exposure outside, must be polluted by dust storm, occurs noise, and during apply oil, there will be leakage of oil situation.
For belt, the easy relaxation problem of chain, although Chinese patent application manual (patent No. 02268778) is pointed out V belt and is adopted the method for regulating wheel tension adjusting, can solve band, chain relaxation problem, but rotating speed is fast, duration is long, when transmission pressure is large, can cause the friction loss that regulating wheel internal bearings is larger, also make belt, service life of chain reduce, impact runs well; And added after regulating wheel, cost is higher, process, debug more loaded down with trivial details.
(3) utility model content:
For the deficiency of traditional kind of drive, the utility model proposes a kind of device that improves the transmission of three wings automatic door, its object is to guarantee the security of operation, stable and reliable of three wings automatic door.
The utility model improves the device of three wings automatic door transmission, comprise driving mechanism and transmission mechanism, difference is that described transmission mechanism is gear drive, comprise and be located at driver pinion and the driven gear wheel being meshed in gear-box, the described driver pinion gearbox input shaft that is coaxially connected, the described driven gear wheel gearbox output shaft that is coaxially connected, described gearbox output shaft connects the door-hinge of three wings automatic door; Described driving mechanism comprises brushless DC electric machine, and described brushless DC electric machine connects gearbox input shaft by reducing gear.
Conventional design, described gearbox output shaft is installed by the bearings at both ends of being located in gear-box.
For effectively improving smooth running, reduce the stressing conditions of bearing, described bearings at both ends spacing is made as 40mm～50mm.
Described driver pinion is made as external gear, and described driven gear wheel is made as internal gear, by driver pinion being engaged in to the mode of driven gear wheel inside, reduces the volume of gear-box.
The design feature vertically arranging according to the door-hinge of three wings automatic door, described gearbox input shaft upwards arranges, described gearbox output shaft arranges downwards, for reducing vertical height, described brushless DC electric machine horizontally set, described reducing gear adopts can realize horizontal direction---the bevel gear reducing mechanism of vertical direction transmission.
Advantage of the present utility model:
1, it is large that the device that the utility model improves the transmission of three wings automatic door has speed reducing ratio, and efficiency is high, easy for installation, and noise is low, long service life, the advantage such as volume is little.
2, the utility model is also applicable to four wing spin revolving doors.
