Dynamic Rigidity (Rigidity of the Rolling Element Set)
The rolling element set with infinitely rigid surroundings and screw connection is calculated here. The calculated values serve only as a cross-comparison between the different rolling bearing types and do not indicate the expected rigidity of the axis. If the machine manufacturer models or calculates himself, myonic can provide these on request.
Static Rigidity (Rigidity of the Bearing Position)
This is a frequently used calculation procedure that takes into account the deformation of the rings and screw connections. The results are only directly comparable in case of application of exactly the same measuring points.
myonic Calculation Procedure
The myonic calculation procedure takes the following into account:
- Adjacent constructions and screw connections according to the standards of the information in the product sections
- Standard preload
- Operating loads applied during calculation
All product groups are based on the same FEM calculation method with exactly defined parameters. This means that all the stated rigidity values of the individual product groups (AXRY/AXDR/AXCR) can be directly compared.
Undersized or poorly executed adjacent constructions substantially reduce the rigidity of the axis. On the other hand, better bearing support structures can also increase rigidity.
In the AXRY series, the axial rigidity and tilting rigidity in the corresponding direction can be increased through whole-surface support of L-section rings. Depending on the thickness of the supporting ring, tilting rigidity can be increased by up to 20%. You can find more detailed information about this in our product sections.
