The performance of an Electric Vehicle Power Unit is directly connected with critical tolerances. Tolerances drive opportunities for performance enhancement with cost reduction. The tests normally used to determine and validate tolerances are both expensive and time consuming with prototype parts. By replacing the initial tests with Digital Twin simulations, results can be obtained quickly, and at a much lower cost. This article discusses one of these tests and the results. 

GWJ Technology GmbH has extended the output option of tooth forms of involute gears. GWJ has extended the output of tooth forms in 2D DXF format in its calculation modules single cylindrical gears, cylindrical gear pairs, planetary gear trains, three- and four-gear train systems, gear racks and involute splines as part of the new versions of its calculation solutions eAssistant and TBK.

With the help of KISSsoft, the user can now estimate the influence of manufacturing deviation on the resulting transmission error and excitation force.
