Consideration of Elastic Gear Bodies and Bearing Rings in Gearbox System

Braunschweig, 27.02.2019 (PresseBox) – GWJ Technology, Germany, a manufacturer and provider of calculation software for mechanical engineering and gear manufacturing, recently introduced a new version of its system calculation.
A major extension is the possibility to consider gear bodies of cylindrical gears as 3D elastic and meshed parts. This functionality of 3D elastic parts (meshed FE parts) for housings and planet carrier, which has been around for years, was further extended. By means of 3D elastic gear bodies, the gear body stiffness can be considered in a better way, especially when it comes to the dimensioning of flank modifications. 3D geometries of gear bodies can be defined using either a polygon or the direct import via 3D STEP / IGES. It is thereby possible to define forces and bearings directly on 3D elastic parts. The extended rolling bearing calculation allows the use of elastic bearing rings for even more detailed analyses. There are several more improvements in the software like the addition of the REXS format, which is developed by FVA (German Research Institute for Drive Technology) for gearbox systems or additional result tables in XLS and XLSX format. Needle bearings type HK and BK are now available. The bearing database from SKF was updated to the latest data and a bearing database from Schaeffler with FAG and INA bearings was added. For documentation points on the shafts, a stiffness matrix can be determined. A new option for supporting positions was integrated too. GWJ provides an outlook on its ongoing activities in software development at this years´ Hannover Messe and shows the latest version of system calculation „SystemManager“ for eAssistant and TBK in Hall 25, Stand A23.
