Powerful new calculation software for monorail guidance systems

Linear • EasySolution is the latest software module to be released by the Schaeffler Group for its popular rolling bearing calculation software Bearinx®. Linear • EasySolution calculates the basic rating life of a driven linear axis that is supported by rolling bearings. The software is easy-to-use with an intuitive menu system that provides clear instructions on how to input data.

The software contains the most commonly used linear axis combinations in pre-configured arrangements comprising a drive, guideway and carriage. There is also an option to freely select an axis combination using up to four guideways and 16 carriages.

“With Linear • EasySolution, we are offering rapid and direct support to our customers. We are therefore supplementing the personal advisory work carried out by our external sales function, which remains at the heart of our customer service,” said Ralf Moseberg, Head of International Sales at Schaeffler’s Linear Technology Division.
 
Linear • EasySolution enables designers to calculate and select the most appropriate linear guidance system at an early stage in their design process. The software simulates the actual stresses and loads on the guidance elements, taking contact angle displacement into account, as well as the non-linear deflection behaviour of the rolling element contacts and the elastic 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 pre-load classes. This enables users to minimise development times for new machine builds.

The calculation tool uses unique software algorithms in order to simulate linear rolling bearings. All the data inputs for calculations, such as axis arrangement, forces and load cases, can be saved for further processing and optimisation. The documented calculation result can then be output as a PDF file.

Other bearing calculation tools on the market typically 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 decisive for fatigue life, is often estimated by the software.
 
Excellent after-sales service and technical support have always been key strengths of the Schaeffler Group. As well as the development and manufacture of high quality, precision bearings, there is a strong focus within the company on rolling bearing design and engineering support. The Schaeffler Group itself has successfully used selection and calculation software programmes for more than 30 years. Examples include Bearinx® and medias®, the company’s electronic product catalogue.
 
Linear • EasySolution is available exclusively online and can be used free of charge without restrictions. After registration – which takes a short time – users can begin calculations straight away.

Linear • EasySolution can be used for calculations across the complete range of INA monorail guidance systems, including linear recirculating roller bearing and guideway assemblies (RUE-E); two-row linear recirculating ball bearing and guideway assemblies (KUE); four-row linear recirculating ball bearing and guideway assemblies (KUVE-B); six-row linear recirculating ball bearing and guideway assemblies (KUSE); two-row miniature linear recirculating ball bearing and guideway assemblies (KUEM); and four-row miniature linear recirculating ball bearing and guideway assemblies (KUME-C).
