Contact ratio is a very important parameter for spur gear designs. When all the parameters are calculated for mating spur gears, you need to be also sure about the contact ratio of mating spur gears are inside the acceptable range.
The minimum acceptable contact ratio that recommended by spur gear manufacturers is 1.2. In general applications, contact ratios of spur gear systems around 1.5.
You can use the calculator below to see the contact ratio of your spur gear mates.
As you see above, the use of contact ratio calculator is very simple. You need to have some information about your spur gear mate system;
Enter the required data above at contact ratio calculator, then click on ‘Calculate!’ button to see contact ratio.
Also you can use MB-Unit Converter tool to convert your units into another unit sets.
If you want to do another calculation, click on ‘Reset’ button then re-enter the values again.
This calculator can be very good companion of you to use it in the phase of spur gear system design.
All the responsibilities of calculations that done with these calculators is on the users.
