  ULTire typeCouplingIs a highFlexible coupling, It has good shock absorption and buffering and better performance of offset compensation between axles. Operating temperature is -20~80 degrees Celsius, transmission torque is 10~20000N.M, suitable for humidity, dust, shock, vibration, forward and reverse. Variable and frequent working conditions, and easy to disassemble, because the elastic element is a whole tire body, it is convenient to disassemble and maintain, does not need lubrication, and is durable and reliable.
Tyre couplingIt is divided into two types: convex type and concave type. The convex type is divided into three types: integral type with skeleton, integral type without bone and radial cut type.The inner side of the tire ring is bonded to the steel frame by a vulcanization method, and the bolt holes on the frame are welded with nuts.When assembling, bolts are used to connect the flanges of the two halves of the coupling, and the torque is transmitted by the friction generated between the tire and the flange end surface by tightening the bolts. The torsional shear deformation of the tire ring occurs when the tire ring is working, so the tire coupling It has high elasticity, has a large ability to compensate the relative displacement of the two shafts, and has good damping, and the structure is simple, does not need lubrication, and is relatively convenient for assembly and disassembly and maintenance.The disadvantage is that the bearing capacity is not high and the overall size is large. As the relative torsion angle of the two shafts increases, the tire shape is twisted, and the axial size is slightly reduced, which will generate a large additional axial force on the two shafts. Increase the bearing load and reduce the life.
When the tire coupling is running at high speed, the centrifugal force of the outer edge of the tire expands outward, which will further increase the additional axial force.For this reason, measures should be taken when installing the coupling to make the direction of stress in the tire opposite to the direction of stress generated during work to offset part of the additional axial force and improve the working conditions of the coupling and the two bearings.
