电动伸缩门的构成
Composition of electric telescopic door
1、伸缩门体
1. Telescopic door body
电动伸缩门的门体是由门体大框、交叉撑、轴(定轴、滑轴)及门体轮等主要部件组成。门体整体为金属结构，按材质又分为不锈钢门体、铝合金门体、压铸铝门体。
The door body of the electric telescopic door is composed of the door frame, cross brace, shaft (fixed shaft, sliding shaft), door wheel and other main components. The door body is a metal structure as a whole, which can be divided into stainless steel door body, aluminum alloy door body and die-casting aluminum door body according to the material.
2、机头
2. Handpiece
机头是由驱动器和电气部分组成，它固定在门体的一端，带动门体伸缩运动，与门体配套使用。
The machine head is composed of a driver and an electrical part. It is fixed at one end of the door body to drive the expansion and contraction movement of the door body. It is used together with the door body.
驱动器(电机)采用涡轮蜗杆电机链条或齿轮传动方式，链条传动为科学常规的设计结构，电动伸缩门的动行平衡使用寿命长，易于养护，故障率低固为市场上绝大部分企业采用的技术形式，齿轮传动方式多为钢板锻造底盘，底盘重量较轻，因此牵引槽型托辊 吸水树脂 天津水处理设备 邯郸断桥铝门窗 唐山防水 检查井模具 沟盖板模具力较弱；齿轮传动需要在油浸封闭的状态下方能发挥使用效力，否则日后维修保养成本较高。
The drive (motor) adopts the worm and worm motor chain or gear transmission mode. The chain transmission is a scientific and conventional design structure. The dynamic balance of the electric telescopic door has a long service life, is easy to maintain, and has a low failure rate. It is the technical form adopted by most enterprises in the market. The gear transmission mode is mostly steel plate forging chassis, which is light in weight, so the traction is weak; Gear transmission needs to be in an oil immersed closed state to play its role, otherwise the maintenance cost will be high in the future
