GL roller chain couplingIt uses a common chain to mesh with two parallel sprockets with the same number of teeth at the same time. The main difference between different structure types of chain couplings is the use of different chains. Common ones include double-row roller chain couplings and single-row rollers. Chain couplings, toothed chain couplings, nylon chain couplings, etc.
GL型滚子链联轴器的维护方法：滚子链联轴器上链轮齿数一般取12～22范围内偶数齿，若取较少的链轮齿数，则链轮上的作用力增加；若取较多的链轮数，则联轴器补偿能力降低，半联轴器上链轮的分度圆直径dp=(12～13．5) 或dp=(2～3．2)d；罩壳外径DK=(1．15～1．2)dp；半联轴器外径D=(O.7～0.8)dp；半联轴器长度L=（1.9～2.8）d，大转矩时，取小的系数。
GL type roller chain coupling has the characteristics of convenient assembly and disassembly, simple maintenance and low cost.
