When changing sprockets you can adjust chain links to maintain nearest to current sprocket centers eg.
Roller chain length formula.
If chain length is fractional round off to the nearest whole number of pitches.
The number of teeth on each sprocket is known.
Chain length in pitches cl 2c a 2 t c note.
Confusion doesn t rule the day when roller chain sizes are detailed in every dimension possible at usa roller chain.
When the distance between the driving and driven sprockets can be varied to suit the length of the chain this center distance for a tight chain may be determined by the following calculator and formula.
Use at your own risk.
Center distance inches links.
An even number of pitches is always preferable to an odd number which requires an offset section.
The algorithm to compute chain length uses sprockets pitch diameters.
For our flt h chain drive conversions we supply a 120 link o ring ek chain.
The chain drive trajectory is based on individual sprocket position and desired direction of motion.
If your centre distance is too short a minimum will be calculated.
Driven sprocket teeth.
Length inches reduction ratio.
The sliding sprocket position is adjusted accordingly.
Compare diameter width and thickness as you find drive chain sizes that move your machinery in the right direction.
We also have a sprocket diameter calculator that determines a sprockets diameter based on the pitch of the chain and the number of teeth.
