Advantage
When assembling, bolts are used to connect the flanges of the two coupling halves. 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, great ability to compensate the relative displacement of the two shafts, good damping, simple structure, no lubrication, easy assembly, disassembly and maintenance.
Shortcoming
The disadvantage is that the bearing capacity is not high and the overall size is large. With the increase of the relative torsion angle of the two axles, the outer shape of the tire is twisted, and the axial size is slightly reduced, which will produce a large additional axial force on the two axles. Increase the bearing load and reduce the life. When the tire coupling is running at high speed, the outer edge of the tire expands outward due to the centrifugal force, 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.
