ML plum blossom elastic coupling development direction

At present, the ML plum blossom elastic coupling is actually because the coupling parts have radial size and small moment of inertia, no clearance, vibration reduction, buffering effect is good, axial, radial and angular compensation ability is strong, is widely used in metallurgy, petroleum, chemical, hoisting and other industries, especially with frequent starting, positive and negative rotation of the middle and high speed conditions. Although the ML plum elastic coupling has good compensation ability of misalignment, the misalignment of the coupling will still produce additional forces and torque to the rotor and bearing system, and these additional forces often bring serious consequences.

The radial deviation and angular error of ML plum blossom elastic coupling are two aspects of the coaxiality of the two connecting axes. The control of radial deviation and angular error is a big difficulty in the coupling assembly process and also an important aspect affecting the mechanical operation. For quincunx elastic coupling, the allowable range of radial deviation and angular error is related to the diameter of the coupling. In order to improve the assembly accuracy of the coupling, it is a way to improve the flatness accuracy of the motor and reducer assembly surface connected with the coupling. In addition, by measuring and determining the center height of the motor output shaft and the reducer input shaft, The use of mechanical dial gauges to assist measurement can make the efficiency of assembly greatly improved.

At present, with the continuous progress of mechanical industry technology, ML plum blossom elastic coupling system fairy has gradually developed towards the direction of high speed and heavy load, people have realized the seriousness of the coupling misalignment problem, many scholars carry out relevant theoretical and experimental research, for the plum blossom elastic coupling misalignment research also first seen in all kinds of standard design.
