品牌：RETZ/我们一直致力于机械设备和测控领域的持续创新，始于2005……进口蛇形弹性联轴器用来连接两轴以传递运动和扭矩的装置，只有在机器停止运转后才能接合或分离。由于制造和安装误差、加载后的变形以及温度变化的影响，蛇形弹簧联轴器连接的两轴不能保证严格对中，但存在一定程度的相对位移。这就要求在设计联轴器时，应采取各种结构措施，使其适应一定范围的相对位移。

进口蛇形弹性联轴器产品用途 Product use

弹性蛇簧联轴器以蛇形弹 轴向嵌入两半联轴节的齿槽内，来实现主动轴与从动轴的联接。运转时，是靠原动端齿面对 的周向作用力带动从动端，来传递权矩，如此在很大程度上避免了共振现象发生，且简片在传递扫矩时所产生的弹性变形，使机械系统能获得较好的减振效果，其平均减振率达36%以上。蛇形弹 采用弹簧钢制造，经严格的加工处理、具有良好的机械性能，使联轴器的使用寿命比非金属弹性元件联轴器大为增长。The elastic serpentinespring coupling is embedded in the tooth slots of the two coupling halvesaxially with serpentine springs to achieve the connection of the driving shaftand the driven shaft. During operation, the driven end is driven by thecircumferential force exerted by the teeth of the primary end against thespring to transmit the weight moment, which largely avoids resonance. Moreover,the elastic deformation generated by the simple piece during transmission ofthe sweeping moment enables the mechanical system to achieve better vibrationreduction effects, with an average vibration reduction rate of over 36%. Theserpentine spring piece is made of high-quality spring steel and has undergonestrict processing and excellent mechanical properties, which greatly increasesthe service life of the coupling compared to non-metallic elastic elementcouplings
