Interference fits for Gears on Knurled shafts 1

[littlefolk]

Does anyone know of any standards I could source for the required interference/knurl fit for transmitting a specified torque through a gear/shaft assembly?

 

[Tmoose]

I think the torque capacity of a steel to steel non-knurled interference is higher and more reliable than a knurled fit.

What size is the shaft? Several manufacturers make tapered bushings to lock hubs to shafts. Ringfedder comes to mind.

Thank you, Tmoose,for the reply. It's decided to use a knurl fit for our application. I just need design it. The shaft is 24mm in diameter. I need find the furmula to do the calculations. Can you help?
