自动车库门开闭装置有着良好的智能判定功能和可靠性能,是车库门系统中的自动控制设备。开闭机是由减速机和离合器组成的,且由限位器连接开闭机。减速机中的电机轴与蜗杆由弹性销轴连接且由蜗杆与蜗轮相啮合的。
The automatic garage door opening and closing device has good intelligent judgment function and reliable performance, which is the automatic control equipment in the garage door system. The opening and closing machine is composed of a reducer and a clutch, and is connected with the opening and closing machine by a limiter. The motor shaft and worm in reducer are connected by elastic pin shaft and meshed by worm and worm gear.
蜗轮、传动套、弹簧、止退垫、螺帽及链轮安装在输出轴上。蜗杆与蜗轮设置在壳体内部,在上壳体的外侧安装微动开关,蜗轮与下壳体之间在配置耐磨套。蜗轮的下部轴套制成m=1的直齿轮,与安装在下壳体下部的限位器齿轮相啮合,随螺杆的转动而产生上下位移。
The worm gear, transmission sleeve, spring, backing pad, nut and sprocket are installed on the output shaft. The worm and worm gear are arranged inside the shell, a micro switch is arranged outside the upper shell, and a wear-resistant sleeve is arranged between the worm gear and the lower shell. The lower shaft sleeve of the worm gear is made into a straight gear of M = 1, which is meshed with the gear of the limiter installed at the lower part of the lower housing, and produces up and down displacement with the rotation of the screw.
开闭机内设计有3-5分钟照明延时;控制系统与减速机装在底板上密封在外壳内既美观大方,又安装方便;装置上的机械式离合器可供在停电时使用,使车库门在停电时能够顺利的用手动开启。离合器壳体内配置离合器拉杆与离合杆,连杆通过销轴与离合器壳体相连接,限位器的上下限位块通过调节杆装在限位器架内,上下触点、触舌安装在上下限位块之间并固定于线路板上。
3-5 minutes lighting delay is designed in the switching machine; The control system and reducer are installed on the bottom plate and sealed in the shell, which is beautiful and easy to install; The mechanical clutch on the device can be used in case of power failure, so that the garage door can be opened manually smoothly in case of power failure. A clutch pull rod and a clutch rod are arranged in the clutch housing, the connecting rod is connected with the clutch housing through a pin shaft, the upper and lower limit blocks of the limiter are installed in the limiter frame through the adjusting rod, and the upper and lower contacts and contact tongue are installed between the upper and lower limit blocks and fixed on the circuit board.
车库门开闭机以及与之相匹配的限位器和控制系统,开闭机体积小,限位器限位精度高重量轻,传动平稳且力矩大,调节容易,系统中增加了过载保护及遇障碍自动回车功能,可很好的确保人车出入平安。
Garage door opener and its matching limiter and control system, the opener is small, the limiter has high precision, light weight, stable transmission and large torque, easy to adjust, and the overload protection and automatic return function are added in the system, which can ensure the safety of people and vehicles.
