Advantages and installation methods of snake spring coupling

蛇簧联轴器又称滑块联轴器，由两个在端面上开有凹槽的半联轴器和一个两面带有凸牙的中间盘组成。因凸牙可在凹槽中滑动，故可补偿安装及运转时两轴间的相对位移。蛇簧联轴器以聚氨脂塑料为弹性元件与二半联轴器主体紧密组合，(组件图)主体以45#钢为多，也有不锈钢体的，根据客户要求定制。材质匀称，避免了因材质不匀称而造成的转动不均匀。表面发黑防锈处理。(主体对比图)中间聚氨脂塑料元件以独 有配方配制，具有高抗温性好韧性强，与一般普通塑胶件质量稳定(优劣对比图)。塑胶元件形状为星形。蛇簧联轴器广泛用于通用机械、水工机械、工程机械、冶金机械、矿山机械、化工机械等多种场合。

　一、蛇簧联轴器的优点
　　1. The main shaft sleeve is made of aluminum alloy, which is light and handy;
　　2. The middle cross slider is available in a variety of different colors;
　　3、安装方便、免维护、可抗油污和电气绝缘；
　　4、结构简单的高扭矩，高刚性，高灵敏度联轴器；
　　5. Allow large radial and axial deviations;
　　6. Absorb relatively high transmission torque;
　　7、寿命长，性能 ；
　　8、不适合高速传动场；
　　9、制作工艺：精车件，表面处理：本色氧 化处理膜片联轴器能补偿主动机与从动机之间由于制造误差、安装误差、承载变形以及温升变化的影响等所引起的轴向、径向和角向偏移。
　　二、正确的选用了蛇簧联轴器它的简单的安装方式是
　　1、紧固螺栓型：这种低成本类型是传统的固定方式。然而，螺栓的前端与端心直接接触，可能会造成轴心的损伤或拆卸困难。蛇簧联轴器
　　2. Clamping type: Use the tightening force of countersunk bolts to shrink the slit and clamp the shaft tightly.It is convenient to fix and disassemble, and will not damage the axis of Qiancheng.
　　3、分离型：分离型的特点是具有  分开的轴套，Snake spring coupling可以不用移动装置而达到固定，拆卸的目的。
　　4. Semi-separable type: One side of this type is a clamping type bushing, and the other side is a separate type bushing. First fix one side of the shaft to the clamping type shaft sleeve, and then install the shaft center at the device end. In the separable bushing.
　　5、键槽型：这种类型与紧固螺栓型一样，是  传统的固定方式，适合较高扭力矩的传动，为防止轴向移动，通常与紧固螺栓型，夹持型并用。
　　The temperature of the oil injection point of the serpentine spring coupling is ≥150℃, which can resist the action of centrifugal force. It has separation stability, no impurities, and does not corrode carbon steel and nitrile rubber. The lithium-based grease is better.Adequate grease is important for the work of the serpentine spring coupling, and it is recommended to check it once a year.Use a dry grease gun to inject grease until there is excess grease overflow in the hole.
　　Since the serpentine spring coupling is in point contact with the curved surface of the tooth, the coupling can obtain greater flexibility.It can be installed to work normally under conditions of radial, angular and axial deviations at the same time.The following methods are mainly followed during installation:
　　（1）两瓣联轴器间的间隙与角向偏差的找正，安装时，每隔90°测量两瓣凌斯蛇形弹簧联轴器间的间隙，其大值与小值之差不超过0.38mm.
　　(2) Correction of radial deviation.Put a ruler on the two-part coupling, measure it every 90°, and check with a ruler, the radial deviation does not exceed 0.38mm.
