   The tire coupling uses a tire-like rubber element to connect the two halves of the coupling with bolts.The structure type of tire coupling is divided into frame type, open type, integral type, split type and so on.
    Compared with the other two types, the framed structure has the advantages of large carrying capacity, long service life, and convenient assembly and disassembly. Therefore, the framed tire coupling is selected as the national standard.The tire-type coupling has high singleness, small torsional rigidity, strong damping ability, large ability to compensate the relative displacement of the two shafts, good damping, simple structure, no lubrication, easy assembly, disassembly and maintenance, and low noise , But the carrying capacity is not high, the radial dimension is large, and a large axial additional load will be generated when overloaded.It is suitable for the two-axis connection with frequent starting, changeable forward and reverse rotation, and large shock and vibration. It can work under dust and moisture conditions. The working temperature is -20~80℃.
Due to various reasons, the center of mass or inertial principal axis of the tire coupling does not coincide with the axis of rotation, and the phenomenon of unbalanced centrifugal inertia, centrifugal inertia couple and dynamic deflection (vibration shape) will occur during operation, which is called the phenomenon of rotor Unbalance phenomenon, this kind of unbalance phenomenon will inevitably cause the vibration of the shaft system, thereby affecting the normal operation and service life of the machine, so it must be paid attention to.
In order to correct or minimize the unbalance of the tire coupling, the appropriate balance level should be selected according to the needs, and after the product is manufactured and installed on the machine, it is on the balance (correction) plane designated by the coupling , By increasing or decreasing the appropriate quality to achieve the balance level requirements, this process is called balance correction, or balance for short.
