Brief Tutorial on Misalignment
The function of a coupling is to connect driving and driven equipment. In addition, a coupling serves to protect costly equipment from the effects of misalignment, shock loads, vibration and shaft end float. Of these factors, the most common is misalignment and end float (also known as axial misalignment).
Misalignment is a condition created by two shafts whose axes are not in the same straight line. There are three forms of misalignment: parallel, angular, or the combination of the two. End float is the relative motion of two shaft ends.

Parallel misalignment occurs when the axes of the connected shafts are parallel, but not in the same straight line.


Angular misalignment occurs when the axes of the shafts intersect at the center point of the coupling.



End float (and Axial Misalignment) occurs when one shaft moves along it’s axis relative to the other shaft.



Misalignment can result from a combination of manufacturing tolerances, poor installation practices, thermal growth or shrinkage, foundation movement, and/or component wear. The combination of angular and parallel misalignment within a system may be more detrimental to the coupling and equipment than either of the individual misalignment.



Axial misalignment- result of either thrust loads, reaction loads, or heat generated movement - compounds the problem. Understanding the amount of misalignment that the coupling must handle or installing a coupling where it exceeds a maximum rated misalignment can result in premature coupling failure and/or significant equipment damage.

Misalignment and Coupling Failure
The life expectancy of a coupling is affected by the degree of misalignment. The larger the misalignment, the shorter the life of the coupling. Misalignment may cause heat generation, fatigue, and an increase in wear in bearings of the drive and driven components

I'm not sure on why you qouted me? From my experience the coupler failer that the OP showed is from misalignment. Lovejoy can say what they want. Some of the most pouros material made.

I quoted you because you were refuting what Lovejoy claims.

I agree, it was probably misalignment. But Lovejoy specifically says they are designed to be used where there is not 100% alignment.

What that point is, the OP found.

 

There are only three spurs on a love joy, so only three of those spider fingers can wear out. The other three spider fingers are behind the coupler spurs. these would wear out if you could run the engine backwards...or forward and backwards...

 

TurboDiesel the quote you referred to was talking about the nylon bushing between the lovejoys
Here's a pic. New replacement is on right

 

yes,
thats exactly how mine looked yesterday when i took it apart. three spurs were completely gone on one half of the coupler also.
at one time the engine bolts came loose and it got really noisy. i didn't realize what was going on till i tried to start the engine and saw it move a little. i tightened the engine bolts and it quited back down. i suspect that's what damaged the coupler.

 

kinda common on the cheap vertical shaft speeco splitters, we see half a dozen or more per year with the ears sheared off completely. they come with L075 series couplers, we swap them out for the larger L095 series as the 75 series is only rated for 3-4 hp depending on how you calculate the load and which brand of coupler your using.

 

Thats exactly what I did.
