GWJ Technology GmbH, a manufacturer of calculation software for machine elements and gears, recently launched a new version of its system calculation for gearboxes. SystemManager enables the user to determine complete systems and is a system add-on to GWJ´s software applications eAssistant and TBK2014.

 

SystemManager supports axially parallel shaft systems for multistage cylindrical gears with or without power split transmission, manual gearboxes, planetary gear trains as well as perpendicular transmission systems. The progress of the nominal tooth force along the facewidth has already been calculated and displayed graphically for single tooth meshes of gear pairs within the system. This load distribution along the facewidth will be considered in the calculation of the load capacity by means of the face coefficient Khß. It is possible now to consider flank line corrections such as lead crowning, end relief or helix angle

corrections in the calculation of the load distribution along the facewidth. Different modifications for the respective gear mesh can be easily checked and graphically displayed. It makes it very easy to find an optimal correction. The new version includes bevel gear stages with shaft angle unequal 90°.

 

In addition, new force elements for worms and worm wheels were added and the new calculation module for worms was connected to SystemManager. A whole series of additional innovations are also featured in this new version. For example, the definition of a stiffness matrix for housing stiffnesses, three-dimensional representation of the load.
