Could someone help Please?
I am trying to mount a driveshaft to an electric motor for a Segway project and determine the required bolt size to prevent failure. The Segway must be able to carry 120kg and is powered by two electric motors.
The drive shaft has a diameter of ø12mm and is 91.6mm long and a section on the end ø45 by 5mm thick with 4 holes on a 30mm PCD for mounting.
the electric motor; 500w
450RPM
26.7A
24v (DC)
1.9n/m (max rated torque)
I have calculated that with a factor of safety of 2, that I would require at least M4 bolts for the required loading of the person.
However, I am unsure on how to calculate the stresses caused by the electric motor and then combine them with the 120kg to calculate the required bolt sizes. any help would be greatly appreciated
