Henan sprocket coupling

Sprocket couplingIt uses a common chain to mesh with two parallel sprockets with the same number of teeth. Chain couplings of different structure types are used. The main difference is the use of different chains. Common ones are double-row roller chain couplings and single-row roller chains. Couplings, toothed chain couplings, nylon chain couplings, etc.The performance of double-row roller chain couplings is better than that of other structural types of couplings. It is widely used and our country has also formulated it as a standard.

The sprocket coupling has a simple structure (composed of four pieces), convenient assembly and disassembly, no need to move the connected two shafts when disassembling, compact size, light weight, compensation ability, low requirements for installation accuracy, stable work, and longevity Longer, lower cost and other advantages.

It can be used in the shaft transmission of textile, agricultural machinery, lifting and transportation, engineering, mining, light industry, chemical industry and other machinery. It is suitable for high temperature, humidity and dusty working conditions. It is not suitable for high speed, severe impact load and transmission of axial force. The chain coupling should work under the condition of good lubrication and protective cover.

链轮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。双排滚子链联轴器性能优越，现已制订为标准；半联轴器的轮毂的外园的径向圆跳动按照GB/T 1184中的8级公差值。

The sprocket coupling is connected with the outer sleeve through spherical rollers distributed along the circumference. The spherical rollers are embedded in the hole between the half coupling and the outer sleeve to transmit torque and bear radial force, which can compensate the reducer. The angular displacement between the output shaft and the axis of the reel is similar to the elastic pin gear coupling.When in use, the half coupling is sleeved on the deceleration reduction output shaft, the outer sleeve is connected with the steel wire rope drum by bolts, and the torque and radial load are transmitted between the half coupling and the outer sleeve through spherical rollers.The spherical roller coupling has the performance of compensating the relative displacement of the two shafts, with compact structure, light weight and convenient installation. It is used for the connection of the mechanism on the crane trolley.
