I can't figure out how to select variable speed belt for our variable speed drive design with the following specifications of our BAJA vehicle: 1.) BHP= 10HP 2.) Max. Belt velocity = 35 m/sec 3.) Max. Engine RPM = 3700

We are designing this variable speed drive for our CVT. Any help regarding the description of selection process will be greatly appreciated.

Thanks in advance!

So, simple analysis is:

max belt speed <= engine speed * gear circumference

Throwing in the numbers and solving for the diameter at the maximum point:

Edit based on a unit error...

D = 35 / ((3700/60) * 3.14159)

which gives 0.18 metres ie 18cm.

That should enable you to work out what you want to use for a final drive ratio..
