What do you know about Gear Coupling Shree Shakti
Know things about Gear Coupling A coupling is a device used to connect two shafts Their ends are connected to transmit power The primary usage of coupling is to join two rotating pieces with a degree of misalignment to allow movement at both ends. Coupling falls into two categories namely Mechanical and Material Flexing.

How vibration analysis can detect alignment problems
For parallel misalignment we look for abnormally high 2X vibration in the plane of rotation on both sides of the coupling Again there may be a combination of axial 1X and/or 2X vibration This type of evidence generally indicates a problem the severity of which depends on absolute amplitudes margins above baseline values and trending.

MisalignmentPrecision Couplings Air Motors
Misalignment or the variance between the intended position and attitude of two shafts is normally the result of manufacturing tolerances and quantifying misalignment is crucial when seeking to specify the correct coupling As the misalignment increases the transmissible torque and life expectancy of the coupling reduce exponentially.
