Online bearing calculation software gains linear moduleSchaeffler is launching a new linear module for its online bearing calculation software BEARINX. This software enables Schaeffler's distributors and customers to analyse rolling bearing arrangements in detail, from single bearings to complex shaft or linear guidance systems.

With BEARINX online linear calculations, users can now determine actual stresses while taking into consideration various loads, as well as the deflection behaviour of the linear bearing, guideway and carriage. Exact calculations for the internal load distribution in the bearing are performed, including contact pressure with the actual rolling element profile and various preload classes. This helps to minimise development times for new machine builds.

Other bearing calculation tools currently on the market normally use more simplified calculation methods. Displacement, tilting and the consideration of rigid or elastic guideways and carriages are often ignored. Furthermore, the internal load distribution in the bearing - which is important for fatigue life - is often simply estimated by the software.

Calculations and data entry can be performed at the desktop via BEARINX’s easy-to-use Java-based interface. Data and geometry for Schaeffler linear bearings is accessed easily from an integrated database. All calculations are performed by servers at Schaeffler, therefore local hardware requirements are low.

3D user interface

The linear module is modelled in an interactive 3D user interface, which helps to freely rotate, move and zoom the calculation model in the display. Linear axes can be designed individually.

Calculations can be performed on a combination of linear recirculating bearing and guideway assemblies based on rollers or balls with track rollers and yoke type track rollers. Calculation of linear bearings on multi-axis machine tools is also possible.

Forces and moments can be entered and acceleration of masses is also taken into account, via several axes if necessary. Working points can also be set to output deformation of the linear system at any location. Compensation for production or assembly errors by means of initial displacement is also possible.

A one-off fee covers registration and a day of training.
