Does anyone knows about gear ratio of Ball-Screw?
When I'm modeling the motor & transmission dynamics, there I must calculate effective mass of motor and there is ball-screw in transmission.
'motor' - gear(1:4) - 'ball-screw'
To know about the effective mass, I must know the gear ratio of ball screw. But through ball-screw, torque is converted into force which tansformation I can not calculate gear ratio.
Is it the (rev/m)? or (ball-screw diameter/lead)?
I wish somebody can help me.
