XINLAN analyzes that the roller chain coupling can take a smaller number of sprocket forces.

Roller chainCoupling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.
    The double-row roller chain coupling has superior performance and has been formulated as a national standard; the radial runout of the outer circle of the hub of the half coupling is in accordance with the 1184-level tolerance value in GB/T 8; the lubrication of the coupling The performance has a significant impact. Grease should be applied regardless of whether there is a casing or not. The half coupling and the cover are not allowed to have cracks, slag inclusions and other defects that affect the strength; the performance is better than other structural types of couplings, which are domestic and foreign Widely adopted, our country has also formulated as a national standard.
    Roller chain couplings have certain compensation performance, but they cannot dampen vibrations, so they are not suitable for shafting transmissions with shocks and vibrations. Roller chain couplings are a type of flexible couplings with no elastic elements. No elasticity Element flexible couplings include: slider couplings, chain couplings, gear couplings, universal couplings, spherical roller couplings, ball couplings, steel ball couplings, etc. The coupling uses a double-row roller chain to mesh with two identical side-by-side sprockets at the same time to realize the connection of two half couplings. The main difference between different structure types of chain couplings is that they use different chains, which are common There are double-row roller chain couplings, single-row roller chain couplings, toothed chain couplings, nylon chain couplings, etc.
