Shock absorbing buffer Avoid resonance Torsion Shaft Coupling for various excavators
Due to the instability of the driving torque of the power machine and the load torque 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 (periodic variable load and It will affect the service life and performance of machinery, destroy the normal working conditions of instruments and meters, and cause additional dynamic stress to shafting parts. When the total stress or alternating stress are respectively When the allowable limit is exceeded, the part will be damaged or fatigued. When designing or selecting couplings for transmitting torque and motion, torsional vibration analysis and calculation should be carried out. Additional loads and stresses arising from systems and transmissions. If you need Torsion Shaft Coupling, St. Regis can provide you with torsional vibration calculation services.
