Interference fits for Gears on Knurled shafts
Interference fits for Gears on Knurled shafts
(OP)
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?





RE: Interference fits for Gears on Knurled shafts
Calculate the pressure created in the interference fit, multiply by the surface area of the fitted area, then multiply by the radius of the shaft and then by the friction coefficient to get the torque.
To be on the safe side assume friction coefficient of say 0.2 (if the area is dry or 0.1 if wet). The resulted torque should be few times larger then the designed transmitted torque.

What I could really do with is a standard or something for knurled fits and the torque transfering capabilites thereof, any ideas?
