This Ball Screw calculation (Version 10/2018) calculates the load distribution and the reference rating life according to ISO/TS 16281 (DIN 26281).
The inner geometry of the ball screws must be provided by the user. The operating clearance can be specified. The loading can be specified as force/moment or displacement/rotation independently for each of the five degrees of freedom. Bearing sets can be defined by using a configuration with multiple rows.
The following results can be found in the report:
•Reference rating life according ISO/TS 16281
•Load distribution between rolling elements
•Reaction forces/moments and displacements/rotations
•Contact pressure for each contact
•Static safety factor
In addition to the report, the results are shown in several graphics. Report and user interface are both available in metric or US customary units. Supported languages for user interface and report are English, German, French, Spanish, Korean and Chinese.
