The importance of universal coupling in work

　　The flexible element of the coupling should not be used for axial adjustment.The gasket set on the high-performance coupling is used to deal with length errors during installation.Couplings with a diameter less than 6 inches (152 mm) usually allow a length error of +062 inches (+1.58 mm), while a coupling with a diameter greater than 6 inches (152 mm) allows a length error of +0.125 inches (+3.2 mm) ).The gasket should be evenly distributed on both ends to maintain the integrity of the flange guide rod.In fact, one of the reasons for the difference between the actual wheelbase and the designed wheelbase is the machine installation tolerance.Another reason is the installation tolerance of the conical shaft hub.

　　The universal coupling is an important component that connects the prime mover and the working machine. Its damage will cause the motor to stop working and even affect the entire running circuit. Therefore, the reliability of the joint is very high.However, the conditions of common couplings often have certain limitations.For example, in the transmission of a rolling mill, due to the restriction of the diameter of the roll connected to the coupling, the rotation diameter of the coupling is also restricted, and the rotation diameter of the coupling is also restricted accordingly. For example, in the transmission of a rolling mill, the coupling The rotating diameter of the device is correspondingly limited.The actual torque during the rolling process is usually close to the fatigue torque of the coupling, even if it is not appropriate, it will be exceeded.If this overload phenomenon occurs frequently, it will greatly reduce the fatigue life, resulting in fatigue failure or damage.

　　In addition, the geometric position of the universal joint is also required.If there is any incorrect situation, additional torque will be produced, which will also shorten its life and affect its transmission efficiency.For large couplings, due to insufficient maintenance technology and improper adjustment of the balance system, the additional load equivalent to the torque level is either large or even destroyed.Therefore, for such core equipment, there must be comprehensive technical control to ensure its life.The universal joint has the advantages of large conveying inclination, high efficiency, smooth transmission, low noise, small gap impact, and large transmission torque.Especially under the correct technical control conditions, a long service life can be obtained, so more and more machines are adopted.For example, the current adoption rate of domestic rolling mills has reached about 70%, the number of large turns is 1200mm, and the transmission torque is 3200kN.m.
