Design Calculators
Getting Started
To use the following calculators, you need to have a rough idea of what the subsystem or mechanism will be. These calculators will not solve the design problems for you, however they will ensure you are using the parts properly.
Using the calculators is an iterative process meaning that you have to make tradeoffs between the perfect distance that you need in the mechanism and what is physically possible with the parts and pieces we use.
Chain Sprocket Spacing
ReCalc has a straight forward chain calculator that can be used to determine the desired sprocket center to center distance based on the ideal distance and sprockets being used.
We have standardized on using #25 chain for most applications. If higher load capacity is needed, #35 chain can be used.
Belt Pulley Spacing
All the theory behind calculating belt spacing and visualizations can be read on WCP's documentation page here:
ReCalc has a belt calculator created for easily determining:
What belt length to use based on ideal center to center distance and pulley diameters
What center to center distance to use based on selecting a specific belt and set of pulleys
Care must be taken to ensure you are using the calculator for belts that we have in stock or can easily acquire. We have standardized on HTD belts which have a 5mm pitch.
Mechanism Calculators
Linear (Elevator) Mechanism
Rotary (Arm) Mechanism
Flywheel (Shooter) Mechanism
Gear Ratio Finder
Once you have found the ideal gear ratio with a mechanism calculator, you can use this gear ratio finder to help identify sets of gears that will acheive the ideal reduction.
This finder can work within the constraints of your subsystem or mechanism with the overall space availble.
