Introduction to XINLAN's Analysis of the Dynamics of Universal Couplings

XINLAN coupling analysis is choosingUniversal couplingAccording to the actual situation and requirements of the users, the above-mentioned factors should be considered comprehensively, and the coupling variety, type and specification that best suits your needs should be selected from the existing standard couplings.
When choosing a universal coupling, you should consider the various factors mentioned above in accordance with the actual conditions and requirements of the users, and select the best coupling varieties, types and specifications that suit your needs from the existing standard couplings.Under normal circumstances, the existing standard coupling can basically meet the needs of different working conditions.
　　Due to the unstable driving torque of the power machine and the load moment of the working machine, as well as the impact caused by the manufacturing error of the transmission parts and the dynamic load caused by the unbalanced centrifugal inertia force of the parts, the transmission shaft system is under variable load (periodically variable load and Non-periodic impact load) will produce mechanical vibration, which will affect the service life and performance of the machine, destroy the normal working conditions of instruments and meters, and cause additional dynamic stress to the shafting parts. When the total stress or the alternating stress are respectively When the allowable limit is exceeded, the universal coupling will cause damage or fatigue damage to the parts.When designing or selecting couplings for transmitting torque and motion, torsional vibration analysis and calculation should be carried out. The purpose is to find the natural frequency of the shaft system to determine the critical speed of the power machine, so as to calculate the torsional vibration of the shaft. Additional loads and stresses generated by the system and the transmission device.When necessary, use vibration damping and buffering measures. The basic principle is to reasonably match the quality, stiffness, damping, and interference force size and frequency of the system, so that the transmission device does not operate within the speed range of the resonance zone, or does not appear within the operating speed range. Strong resonance phenomenon.Another effective method is to use high-flexibility elastic couplings in the shafting system, referred to as high-elasticity couplings, to reduce the natural frequency of the shafting system and use its damping characteristics to reduce the torsional vibration amplitude. .
