HI I don't know what kind of chain drive you have. Chain wear is based on 3% of 12.000 inches,that is .360" per foot,(12.360")after this the chain will ride up on the sprocket and jump off. The maximum life of a chain drive is about 15,000 hours if you follow mfgs installation and lubrication instructions. Therefore if you divide 15,000 hours by .360 you will get the wear per hour. Based on theory only. George

I think your question is not obvious to me, as I am not aware of a reliable way to calculate chain wear.  In general, this information is determined by the chain manufacturer and is normally determined by experiment and simulation. As far as chain wear goes, poor lubrication is probably the biggest contributor to excessive chain wear. Most chain manufacturers provide guidelines for SAE-rated lubricant viscosity depending on chain size, application method, and operating temperature. Determining the frequency of maintenance application of lubrication depends largely on the operation, chain speed, and environment. Maintenance folks should have a plan on how often  to lubricate to prevent excessive chain wear

I agree, ... additional factors that weigh heavy are alignment of the sprockets and load. .... so many variables. -randy- The worst suggestion of your lifetime may be the catalyst to the grandest idea of the century, never let suggestions go unsaid nor fail to listen to them.
