The universal coupling is used to couple two shafts (master and driven shafts) in different mechanisms to rotate together to transfer torque to mechanical parts. In the high-speed heavy-duty power transmission, some couplings also have the role of cushioning, damping and improving the dynamic performance of the shaft. The coupling consists of two halves, which are connected to the drive shaft and the slave shaft, respectively. General power machine mostly by means of coupling and working machine connected. The choice of coupling mainly consider the level of the required transmission shaft speed, the size of the load, the installation accuracy of the two parts connected, the smoothness of the rotation, the price, etc., refer to the characteristics of various couplings, choose a combination of Coupling type.

    Universal coupling of the transmission that can be used sliding drive, you can also use the rolling drive. When using the sliding drive, in order to buffer and vibration, in the arm and force arm mounted on the polymer buffer sleeve. When the use of rolling transmission, then the arm and the arm on the original set of the buffer sleeve 3 was converted to rolling parts, while the ball and the cup between the original will also be replaced by a rolling pad to match Rigid drive needs.
