Shaft Coupling

20th century 25 years, reversing the vibration on the primitive equipment is unobservable, because the drive shaft vibration and stability of the distortion of the average rotation rate is overlap. Has served as MIT (Massachusetts Institute of Technology) Mechanical Engineering Department led by Professor Edward Miller conducted an observation and found to reverse the destructive shear vibration. In the diesel engine-driven pump in the original trial, he mentioned to connect the engine and the pump shaft until the complete failure to start shooting "cherry red" color of light. Amount of destructive energy, the phenomenon of torsional vibration is only the consequences of the time, until the failure occurs, torsional vibration can only be real and tangible.

     Engineering knowledge has been greatly moved forward, since that time, the torsional vibration is no longer as mysterious as before. Each engine manufacturer can provide detailed information on torsional resonance, design engineers can ensure that the system of torsional vibration levels in the permitted range. The new solution is to be installed between the diesel engine and a flexible shaft flexible coupling or reverse, the engine and system isolation and its harmonics. Commonly used for this purpose, there are two types of flexible couplings, one is compressed rubber coupling, and the other one is inside the cut rubber coupling.
