What is the tiredness torque of the cardan shaft (universal joint shaft-industrial drive shaft)
摘要:What is the tiredness torque of the cardan shaft (universal joint shaft-industrial drive shaft)
Cross cardan shaft- universal joint shaft has a big transmission Angle, high efficiency, smooth transmission, low noise, small clearance impact, transmission torque, and many other advantages, especially under the condition of the correct technical control can also get a long service life, so it is more and more has been adopted by all kinds of machinery.Such as: the current domestic mill adoption rate has amounted to about 70%, maximum turning diameter of 1200 mm, the transmission torque of 3200 kn. M.Coupling is an important part of a machine join prime mover and work, it will cause damage to the machine pause, and even spread to the whole production line, so the high reliability requirement.But the cross cardan shaft universal coupling of the conditions and is often very demanding, such as: in the rolling mill drive, due to the connection of the diameter of the roll have certain limitations, thus turning diameter of coupling 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 cross shaft - universal joint shaft coupling space geometric position request also is higher, if there is improper, there will be additional torque, these additional torque would also reduce the transmission efficiency and influence their life.For large coupling, due to improper maintenance technology does not reach the designated position adjustment and balance system, also can bring the equivalent of torque levels of the additional load or larger, some even make the cross shaft broken.So, for such a core equipment, want to have a comprehensive technical control, to ensure its longevity.
