LA, RF tire coupling tire body

LA, RF tire couplingThe tire body is divided into two types: convex and concave. The convex is divided into three types: integral with skeleton, integral without bone and radial incision.Their common feature is that the tire ring is bolted to connect the two halves of the coupling to realize the connection of the two shafts.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 coupling halves. The friction force generated between the tire and the flange end faces by tightening the bolts is used to transmit torque. The torsional shear deformation of the tire ring occurs when the tire ring is working, so the tire coupling It has high elasticity, a large ability to compensate the relative displacement of the two shafts, and has good damping, and has a simple structure, does not require lubrication, and is relatively convenient for assembly and disassembly and maintenance.The disadvantage is that the load 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 achieve the working conditions of the coupling and the two bearings.
