Detailed parameters of LLA type non-framework tire coupling
  The tire coupling for LLA metallurgical equipment is a highly elastic coupling with good shock absorption and excellent performance of offset compensation between shafts. The operating temperature is -20 to 80 degrees Celsius, and the transmission torque is 10 to 20000N. M, suitable for wet, dusty, shock, vibration, variable forward and reverse and frequent starting working conditions, and it is easy to disassemble and assemble without lubrication, and is durable and reliable.
  Non-standard couplings are made according to special needs. When overloaded, the clamping flaps of the half couplings will work, and no malignant accidents will occur. Its structure is marked as M, and the standard half coupling structure is K type. Can no longer mark in the presentation.

The LLA type non-framework tire coupling is a coupling that is fixed by two half couplings and a tire body through a pressure plate and bolts. The torque transmission is completed by the extrusion and deformation of the tire body.The structure type of tire coupling is divided into frame type, open type, integral type and split type.
