What is the effect of coupling types on rotor vibration?
The coupling type and increase in shaft speed has a great influence on rotor vibration. Investigation of the factors influencing the rotor vibrations due to coupling type and increase in shaft speed will help to improve the design and control of a rotor dynamic system.
Who are the manufacturers of shock and vibration damping components?
A D V A N C E D A N TI V I B R A T I O N C O MPO N E N T S ii Designatronics, Inc., with its divisions and subsidiaries, has been involved since 1960 in the manu- facture and distribution of different mechanical and electronic components.
What is the function of a coupling type?
The basic function of a coupling is to transmit torque from the driver to the driven piece of rotating equipment. The coupling type and increase in shaft speed has a great influence on rotor vibration.
How does axial force and misalignment affect rotor vibration?
A.Askarian,S.M.R. Hashemi[4] studied effect of axial force, unbalance and coupling misalignment on vibration of rotor gas turbine. It is reported that for unbalance highest amplitude is at 1X of the shaft speed and for misalignment highest amplitude is at 2X of the shaft speed.
Is there vibration damping in elastomer insert couplings?
A customer sizing an elastomer insert coupling recently asked us if using a larger body size would provide better vibration damping. In a word, the answer was, yes. Vibrations in machine shafts come from a wide variety of sources. Machines that crush and shred materials can impart quite a bit of vibration into the drive line and prime mover.
Why do you need splined shaft clamping couplings?
A flexible tire on these couplings safeguards components on your shafts by reducing vibration and shock. For use with splined shafts, which are commonly found in gearboxes and pumps, these couplings are capable of transmitting more torque than couplings for round and keyed shafts. Connect splined shafts to keyed shafts.
Why do you use gear shaped misalignment couplings?
Couplings compensate for angular and parallel misalignment. Use these gear-shaped couplings for high-speed and high-torque applications. A flexible tire on these couplings safeguards components on your shafts by reducing vibration and shock.
What does a coupling do to an engine?
Along with excellent vibration dampening the coupling will offer protection to both the engine and driven equipment when higher inertias are present. The coupling acts as a mechanical fuse, in the event of an overload condition. The coupling is designed to fail through the rubber and shear.
