UL tire coupling detailed parameters

 

The UL type tire coupling is vulcanized and bonded together with a rubber element (tire body) and a metal pressure plate, and the two halves of the coupling are directly connected with bolts during assembly.The working temperature is -20~80℃, and the nominal torque is 10-25000N.m.
Features of tire coupling:
1. Simple structure, no lubrication, easy disassembly and maintenance, no need to move the coupling axially when changing the tire body.
2. It has high elasticity, low torsional stiffness, strong vibration damping ability, and great ability to compensate the relative displacement of the two shafts.
3. It has good damping and low noise, but the load-bearing capacity is not high, the radial dimension is large, and a large axial additional load is generated when overloaded.
4. It is suitable for two-axis connection with frequent starting, changeable forward and reverse rotation, and large shock and vibration. It can work under dust and moisture conditions.
 
UL tire coupling is a kind of highly elastic coupling. In addition to its excellent cushioning and shock absorption performance, it has excellent compensation performance for axial, radial and angular deviations, which can effectively reduce the equipment during operation. The current peak value is reduced by 50% compared with other couplings.Through the special rubber process design, in addition to no lubrication and maintenance-free, it is especially suitable for humid and dusty working environments.
The standard half-coupling structure is type K, which can no longer be marked in the display.
