Ball spline for linear to rotary motion
Ball spline for linear to rotary motion
(OP)
Does anyone know if there is a manufacturer of 'extremely course ball screws'? Perhaps the device might be considered as a ball spline with twist.
Operationally - Linear motion of the shaft causes the 'block' to rotate. The desire is that 2" of travel will result in 30-degrees of rotation. It should be a precission device and handle a thrust of approximately 500 lbs.
Thanks.

If you think about it - most people test the smoothness of a ballscrew driven actuator by pushing the top table of the actuator long - which is exactly what you are talking about - linear to rotary. You push the table and it spins the shaft.
