Universal coupling has large transfer Angle, high efficiency and flat transmission

The universal coupling uses high-strength bolts and self-locking nuts to connect the flanges at both ends to other mechanical components, and the conveying moment is transmitted through the flange end key and the friction between flanges. Universal coupling has the advantages of large transfer Angle, high efficiency, smooth transmission, low noise, small gap impact, large transmission torque and so on. Especially in the correct technical control conditions can also obtain a very long service life, so has been more and more used by a variety of machinery. For example: at present, the adoption rate of domestic rolling mill has reached about 70%, the extra-large rotary diameter is 1200mm, the transmission torque is 3200kn.m.

Universal coupling is an important part of the connection between the prime mover and the working machine, its damage will lead to the pause of the machine, even affected to the whole line of work, so the reliability of its requirements are quite high. However, the conditions of universal coupling often have corresponding limitations, such as: In rolling mill drive, due to the connection of the diameter of the roll is relatively limited, and coupling turning diameter also restricted accordingly, during the process of rolling torque is often close to the fatigue of the coupling torque, slightly improper will exceed the overload phenomenon such as frequent, can significantly reduce the fatigue life, so that the premature failure or damage.

In addition, the geometric position of the universal coupling space requirements are also high, if improper, there will be additional torque, these additional torque will also reduce its life and affect its transmission efficiency. For large couplings, due to the maintenance technology is not in place and the balance system adjustment is not appropriate, will also bring the equivalent of torque level of additional load or greater, some even make the cross shaft broken. Therefore, for such a core equipment, there should be comprehensive technical control to ensure its life.
