The coupling consists of two halves which are respectively connected with the driving shaft and the driven shaft. A cross-shaft universal coupling is one of the most commonly used couplings. By utilizing the structural characteristics, the two shafts which are not in the same axis or have larger angle of refraction or larger axial movement can continuously rotate at equal angular speed, and the torque and the movement can be reliably transmitted. The torque transmission device can be widely applied to mechanical shafting in lifting, engineering transportation, mines, petroleum, ships, coal, rubber, papermaking machinery and other heavy machinery industries.
