DESIGN AID
If the characteristic load data and the dynamic base load “C” of the ball spindle are known, the calculation can be done using the following formulas:
- Nominal life duration in number of rotations:
[turnaround] where:
Fm = average axial load [N]
C = dynamic base load [N]
- Nominal life duration in hours:
[Nm] where:
nm = average RPM [min-1]
With the variable speed and variable axial load force that characterise the use of a ball screw, the operating cycle of the ball screw must be broken down into a few typical working phases. The values nm and Fm of the above formulas must be calculated from the speeds and axial forces characteristic of the typical working phases
- Average RPM:
where:
qi = time rate of the i-th phase [%]
- Average axial load:
[N]
where:
F i = axial load of the i-th phase [N]
n i = RPM of the i-th phase [min-1]
n m = average RPM [min-1]
q i = time rate of the i-th phase [%]
[N] where:
(Fm; n m values according to the formulas above)
- Driving torque – for conversion of rotary motion into linear motion
[Nm] where:
P = pitch [mm]
η = efficiency (~0,9)
- Drive performance
[kW] where:
n = RPM [min -1]
USER GUIDE
Ball screws require precise and rigid installation. Both the parallelism deviation between the spindle and the guide rail and the deviation of the nut mounting inclination must be kept within minimum tolerances.
The ball screw endings are designed according to drawings provided by customers. The ISO 3408 EU standard shall be used as a guide for the specification of tolerances on shape and positioning corresponding to the accuracy class.
Ball screws can be lubricated with basically the same lubricants as rolling bearings, but the lubricant consumption is higher. The lubricant can be oil or grease. Oil lubrication allows higher speed because the it heats up less, than grease lubrication.
For grease lubrication, re-lubrication every 6 months or so after the running-in cycle is sufficient.
