German NU2226E coupling NU2226E model NU2226E price

NU2226E couplings are divided into two main categories: convex and concave. The convex type is further divided into three types: integral with skeleton, integral without skeleton, and radial slit. The inner side of the tire ring is bonded to the steel skeleton by vulcanization, and nuts are welded at the bolt holes on the skeleton. During assembly, bolts are used to connect the flanges of the two halves of the coupling. Torque is transmitted by the friction generated between the tire and the flange end faces when the bolts are tightened. The tire ring undergoes torsional shear deformation during operation, so the tire coupling has high elasticity, a large ability to compensate for relative displacement of the two shafts, and good damping. Moreover,
