Tire Coupling

Tire coupling tire body is one of the necessary spare parts of tire coupling, correspondingly divided into UL, LA, LB tire bodies. Tire couplings are divided into two types: convex type and concave type. The convex type is divided into three types: integral type with frame, 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.

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.
