LB type tire coupling two forms

LB type tire coupling designed by various manufacturers is mainly divided into convex type and concave type two categories, the convex type of the coupling is divided into skeleton integral tire coupling, boneless integral tire coupling and radial incision type tire coupling three. The inside of the tire ring is bonded with the steel skeleton by vulcanization method, and the bolt holes on the skeleton are welded with nuts.

LB type tire coupling in the process of assembly with bolts and two half coupling flange connection, rely on tightening the bolt between the tire and flange end face generated friction to transfer torque, tire ring when working torsional shear deformation, so tire coupling has a high elasticity, compensation two axis relative displacement ability is large, and has good damping, And simple structure, no lubrication, assembly and disassembly and maintenance are more convenient. Its disadvantage is that the bearing capacity is not high, the overall size is large, with the increase of the relative torsion Angle of the two axles to make the tire shape torsion, axial size is slightly reduced, will produce a larger additional axial force on the two axles, the bearing load increase and reduce the life.

LB type tire coupling in the process of high-speed operation, the operator will find that the coupling parts of the tire outer edge of the centrifugal force to expand outward, will further increase the additional axial force. Therefore, measures should be taken when installing LB type tire coupling, so that the direction of stress in the tire is opposite to the direction of stress generated during work, in order to offset part of the additional axial force, to improve the coupling and two bearing conditions.
