Online Software Calculates Bearing Stresses
Schaeffler has released a linear module for its Bearinx online bearing calculation software. Bearinx enables distributors and customers of Schaeffler linear products to analyse rolling bearing arrangements in detail, from single bearings to complex shaft or linear guidance systems. With Bearinx Online Linear Calculation, users can now determine actual stresses, while taking various loads, as well as the deflection behaviour of the linear bearing, guideway and carriage, into consideration.
Exact calculations for the internal load distribution in the bearing are performed, including contact pressure with the actual rolling element profile and various pre-load classes.This enables users to minimise development times for new machine builds.Other bearing calculation tools normally use more simplified calculation methods.
Displacement, tilting and the consideration of rigid or elastic guideways and carriages are often ignored.The internal load distribution in the bearing is often simply estimated by the software.
With Bearinx Online Linear Calculation, users can perform calculations and data entry at their desktop via the software's Java-based interface.Data and geometry for Schaeffler (INA) linear bearings is accessed from an integrated database.
All calculations are performed by servers at Schaeffler, therefore local hardware requirements are low.The linear module is modelled in an interactive 3D user interface, enabling the user 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 multiaxis machine tools is also possible.
Forces and moments can be entered and acceleration of masses are also taken into account, via several axes if necessary.Working points can also be set, enabling users to output deformation of the linear system at any location.Compensation of production or assembly errors by means of initial displacement is possible.
